I was taught , back in the 70’s, to always use pan head screws when mounting boxes to avoid sharp edges on the heads of other types of screws that could cut the insulation. Also to ALWAYS add the green insulated ground wire, especially in damp areas, because the conduit connectors could loosen, rust or corrode and cause a high impedance ground system. Also if the box cover screws are loosened or removed, the ground is lost! Better safe than sorry! Don’t cut corners! I guess I had a good teacher!

I agree w Bob, if that locking nut on the inside of the AC panel doesn't bite into the manufacture's finish on the panel, you would have a ground continuity issue. Green wire ground is best.

I saw some ''pro'' work where the guy had 'grounded' the EMT by running a 10' length of bare ground wire a few feet into the conduit. Folded it over to increase the contact area. Did that at each end of a 60' run. Only reason it got noticed was that people were getting bit.

[@pld8993]

There's no issue with properly installed EMT fittings and rust, corrosion, or just magically loosening. EMT is installed outdoors all the time so an indoor potentially damp area is of no concern. I learned to install EMT properly when I first started and to this day I don't run wire grounds unless there's a particular reason to do so. The NEC lists 14 types of grounding conductors; only 1 of the 14 is a wire type conductor.

Run the ground. You’re there already. If foregoing the ground wire, at the very least bond the receptacles to the 1900 boxes. The receptacles will be grounded once mounted, but bonding them to the box is a sure fire way to make sure the ground will never be a failure point. Just my 2 cents

[@Sembazuru]

I agree. I don't know NEC, but I used to plan wiring inside medical equipment and had to follow IEC-60601. One of the things that my engineers drilled into my head (so they didn't have to redo my ground path planning) was to never rely on a mechanical connection for grounding. Always intentionally supply a dedicated grounding path. OK... I expect that electrical standards for medical devices are a lot more stringent than housing codes. But for such a short and easy run, put in the dedicated grounding path just for good measure.

[@pld8993]

@@Sembazuru EMT is a dedicated grounding path. Isn't a ground screw also a mechanical connection?

[@Sembazuru]

@@pld8993 If the only thing a ground screw is doing is connecting a ground, that isn't considered a mechanical connection for what I was talking about because the ground screw's function isn't to hold mechanical things together. Mechanical connections would be things like PCB mounting screws and standoffs, screws holding panels onto boxes, outlet mounting screws, conduit set screws, etc. Basically anything that is expected to hold things together under mechanical load and/or vibration. A wire not under tension isn't enough load to be considered a mechanical load. Even conduit that is supported on a wall to regulations will be seeing mechanical stresses at the connection to the electrical boxes as the conduit stretches and contracts due to changing temperatures.

[@pld8993]

@@Sembazuru So changes in temperature or ambient vibration affect the conduit but not the ground screw connection within a box that's connected to that conduit? Assuming an equal amount of temperature change, copper and aluminum are subject to greater levels of expansion and contraction than steel. Using your own description of a mechanical connection, a ground screw absolutely falls into that category. FYI, electrical engineers aren't automatically electricians (though many believe that they are) and should not be trusted to know what they're talking about when it comes to the electrical trade unless they are ALSO electricians. Conduit systems, when installed properly, are more than sufficient as EGCs and while running a wire type EGC isn't wrong, it's usually unnecessarily redundant.

[@kookiedabear]

To be clear - While it is ideal to use individual conductors, it is NOT required by NEC. As long as there is enough room (per the NEC table) inside the conduit, you are allowed to use NM (sheathed) wire.

[@MrOpinionCantSignIn]

Admittedly I always believed it was not propper too but could not see changing back and fourth going to islands , so I ran oversized conduits and finally just looked it up , then asked an inspector if I missed something and they were just letting it slide ... nope, perfectly legal

[@thesmallterror]

The problem is the NEC table examines conductors by their diameter and the NM cable has to be treated as one giant conductor, because it is explicitly said as such in NFPA 70 Chapter 9, Paragraph #9, which reads: "A multi-conductor cable, optical fiber cable, or flexible cord of two or more conductors shall be treated as a single conductor for calculating percentage conduit or tubing fill area. For cables that have elliptical cross sections, the cross-sectional area calculation shall be based on using the major diameter of the ellipse as a circle diameter." As NM is an elliptical cable it gets classified as if it were a massive circular conductor, which means NM-b cable needs an unusually massive conduit. After working through Chapter 9 Article 358, the conduit size for single 14/2 gauge NM cables with ground, each 9mm across, needs to be 3/4 inches. 12/3 cable (12.5mm across) needs 1 inch conduit. The same 15 amp / 14 gague circuit in THNN conductors would fit 7 times in a 1/2" conduit (7 hots, 7 neutrals, and using the tube as ground for all 7 circuits), and the same multi-wire branch 20 amp circuit would fit three times in a 1/2 conduit (6 hots, 3 neutrals, tube as ground) for a total of 6 20-amp 120 volt circuits. One of the other common issues with NM-B inside conduit is you may be using conduit because of a wet location. NM-B isn't allowed here at all, but THNN is. Finally, stripping the cables out of the NM-B jacket is a bad idea because only the jacket has the "NM-B type" listing and Underwriters Laboratory certification printed on it. The cables inside have no type listing; your inspector will consider this "non-listed cable" even if its comparable to THNN type cable. Do I care? No. Does your inspector? Probably.

[@Satchmoeddie]

@@MrOpinionCantSignIn You do where I live. It used to be okay to use the conduit as a path to back ground, but not any more. NM cable in conduit is also no longer allowed anymore. That can vary from jurisdiction to jurisdiction, but we can't do it anymore. We also cannot strip back MC and go from MC to EMT and run the wire in the MC in EMT. The MC manufacturers no longer stamp the wires inside the MC with the type & ratings so that makes it illegal now. The wires have to have the 600VW rating, the type of insulation, etc. marked every 2 feet, or you can't use it. Back in the 20th century the wires inside MC cable were all marked like 600WV spool wire. NAFTA screwed that all up.

Tip for tapcons... I always have a spool of bare galvanized wire handy (18-16GA). Just before you put the tapcon in, take a piece twice the depth of the hole plus an extra inch and double it over. Insert it into the hole leaving about 1/2" exposed and bend over the extra, then drive the tapcon in. It helps make it bite even better and especially in loose holes or brittle concrete. I would also always run the green ground wire for any circuit in conduit. You never know if the conduit/connections/screws become loose over time and cause bad bonding.

Electrician here. While you said it was just best practice, there is nothing against code running NM cable in conduit like in your thumbnail. You do have to follow cable fill requirements in Chapter 9, however. The problem most people make is stripping the jacket off and just using the wires inside. Unlike MC or spooled wire, the conductors inside NM cable are not labled with their insulation class or any other required information, and not permitted to be run in conduit without the jacket. You used solid wire, so I hope you didnt strip the romex and use it for this reason. While it is true EMT is a permitted EGC in 250.122, you are relying on the set screws and locknuts being tight for that grounding and bonding purpose. They can loosen over time, so its not a bad idea to pull a wire type EGC. Also, code has NO prohibition for using a bare grounding conductor for this installation.

[@alryky30]

Totally agree. Best practice is to run grounding if you can. Trusting "BONDED" grounding is a dice roll at best as stated. Equipotential for all of your circuits is key, heaven forbid a child or anyone else plug something in on a loose "BONDED" box and then when finished noticed this and used their one hand to support the box and the other to remove the plug. The possibility of a fault that "EXPOSES" itself could be very dangerous.

When it comes to bonding and equipment grounding conductors (egc's), the system should be designed such that a single point of failure does not degrade the integrity of the system. In order to ensure this, it must be understood that bonding and egc's are two different things. Bonding is intended to tie all metal surfaces together to guarantee that they are all at the same electrical potential in order to prevent a potential difference between adjacent metal surfaces that can cause a shock or an electrocution should someone inadvertently complete circuit between them. The egc is intended to provide a dedicated conductor to carry electrical fault current back to the source to complete the circuit and instantly trip the overcurrent protection to de-energize the circuit in order to reduce the risk of fire and electrocution. Tying the bonding system to the egc, ensures that an electrical fault on the bonding system will trip the overcurrent protection and de-energize the circuit. Relying on the bonding system to act as the egc significantly increases the risk that a high resistance connection will develop over time either through corrosion issues, loosening of bonding screws, or other potential ways that the bonding can degrade or fail. Having a dedicated egc ensures that the fault current path is not reliant on the state of repair of the bonding system. It further ensures that each metal box and fixture are independently bonded to each other at the main panel through their respective egc's. Even if the emt bonding screws come loose or individual bonding connections become compromised, each box and fixture will still remain bonded to all the other boxes and fixtures through their respective egc's. In addition, in the case of emt, even if one end has its bonding compromised, the other end can maintain the bond and keep the conduit at the same potential. Such a design ensures system reliability in the presence of a single point of failure. Of course, you can have bonding failures at both ends of the emt, but, that would be 2 points of failure, and attempting to design a system that remains reliable in the presence of any 2 points of failure is nearly impossible, and even if possible is so expensive that it becomes unaffordable. Also, in order for the emt whose bonding is compromised at both ends to become energized, the wires within would need to be compromised, which may happen if a wire was skinned during the pull, or during subsequent maintenance or repair activities, but that would be a 3rd point of failure. In the case of your installation, a single point of failure compromises the system to save the cost of a bit of wire. It's a very bad design.

However, if the situation were such that utlizing the provision results in a large cost savings on a much larger project, then appealing the decision may be the better way to go. Also, I agree that having a conversation with the inspector can be beneficial in most cases provided that you are knowlegeable about the code and have high quality workmanship. However, if the inspector knows that the homeowner is doing the work they are going to come to the site prepared for a disagreement and such a conversation may not go well. I've had inspectors express great relief that the work was done so well and that they had geared themselves up for an argument. An inspector in that state of mind dealing with a non-expert homeowner may not be the best combination. That being said, high quality workmanship goes a long way with inspectors. As far as us writing these long narratives, I think it's useful to have these conversations because people who don't understand why things are in the code have a chance to learn a little bit.

They don’t think twice about sliding conduit apart and leaving it that way which is another reason why I would never run conduit without a ground wire, you never know what kind of idiot is going to mess with it after you’re done.

Correct me if I'm wrong. I believe a grounding conductor that makes a bond to each metal box needs to be present to satisfy code in this particular arrangement. The set screw on the conduit connectors may loosen or go missing which results in poor continuity as an EGC over time. But of course, this is permissible by code. However, I believe having the conduit and boxes as an EGC is not enough. There needs to be bonding jumpers from those types of box cover plates to the inside of the 4x4 boxes. NEC 250.148 Continuity of Equipment Grounding Conductors and Attachment in Boxes.

The screw or locknut loosening over time could happen but I don't think that potential failure would make the grounding through conduit against code.

So nice to see conduit being used. As an old timer who grew up in Chicago, the sight of Romex being run through holes in studs and into plastic boxes has always left me a bit jarred.

That's correct. And every 10 feet for straight runs. If the box is 3 feet or less to the breaker it doesn't need to be supported as it's supported on the end but should still maintain that every 10 feet standard.

It would be interesting to see what the resistance of the conduit was at install and over time.

The GFCI does not give a pass on grounding requirements or integrity, it is a device and as such can be easily damaged or fail, resulting in loss of GF protection. While Code allows conduit to be used as a grounding conductor, it is in the REAL WORLD a bad practice. Any damage to fittings can cause a high resistance or lost grounding path, which is dangerous. And candidly, with such a short run there is absolutely NO EXCUSE for not using a separate grounding conductor, NONE.

On cutting conduit, if you are going to use a plumbers pipe cutter, use a reamer like a Klein 85191 to ensure that you have expanded the inside of the pipe to required dimension. The pipe cutter squeezes reduces the inner diameter and can catch wire. You did ream, but that does not confirm it's enough. For your install here, it's not going to matter, but for ones with some conduit bends, it can nick/strip wires. Preferred for cutting is a bandsaw (fast and square) or in a pinch a recip saw, but understand those not being standard DIY arsenal.

If this is a damp location you should pull THWN/THHN stranded wire in the conduit. Beyond this you have several options as to the installation that fall under workmanship and technically would not be a code violation depending on the state you live in of course and how the local codes are worded and who is doing the inspection. I would recommend the following: 1) Make the branch circuit 20Amp you are literally at the main breaker box there is no reason to run a 15Amp 120VAC branch circuit. Better yet for a square D breaker panel you can use a tandem 20Amp breaker, string two 20Amp branch circuits and alternate in each quad box, one GFCI #1, and the other GFCI #2 in the same box, then alternate the same in the next box. 2) Use THWN/THHN 12AWG stranded wire (will work for damp basement locations). For one circuit use Black, White, Green (don't rely on the conduit for ground fault protection or GFCI leakage detect always run a ground wire even if you run rigid conduit). For two branch circuits you could use Black (line), White, Green, Red (Line), Yellow (or White marked), Green with Yellow stripe (or Green Marked). You would be pulling 6 wires which would not violate the conduit fill or box fill. Stranded wire is much easier to use in creating a longer pigtail while folding into the box. It is always better to have a slightly longer pigtail for repair or future work. Use a dedicated box stranded 12AWG wire ground screw with captive spade lug to ground each receptacle to the box and the circuit ground. In the video you have the proper boxes in that they have the bulged ground connection for use against a flat masonry brick wall. 3) For 4 total duplex receptacles, use four GFCIs, I dislike ganging GFCIs because if you trip a GFCI you will lose all of the receptacles. 4) Use the industrial version of the GFCIs (local code may require tamper proof version). The quality is much higher, and the wire connection screws are larger and more robust. They also have versions that are prewired using stranded wire or solid wire but are not always in stock. 5) For stranded 12 AWG Wire I use ferrules at the breakers. I like the square style crimp it fits nicely under the breaker screw clamp and keeps its shape. Don't forget to torque the breaker screws to specification, for Square D it is listed on the breaker body. 6) I like using crimped captive spade terminals to the receptacle screws, if the receptacle will not accept spade terminals I use ferrules, but here I like a hex crimp style. To daisy chain you can use twin wire ferrules two wires into one ferrule. You could also use butt splices (some are even step up and step down to allow two wires in one side of the crimp) with high temp heat shrink. To pass inspection it is good to have branded terminals and ferrules used with the branded or approved crimping tools. For example you would use Weidmuller ferrules with Weidmuller ferrule crimpers. When you use a spade lug under a screw head, like you would see if you build industrial control panels, you have a flat connection under a flat screw head, and once this is torque properly (screw is stretched) it will not come loose. I don't like putting a solid round wire around a screw if I can help it, and I certainly don't like to put a stranded wire around a receptacle screw and I never use the back stab easy insertion connections. 7) Use offsets where so the conduit is flush with the wall. Always support conduit with at least one wall strap even if the boxes are close together. With EMT you can bend your own offsets, or you can also buy premade EMT offsets. Bending EMT is not all that difficult it just takes a little practice. If the premade offset is too large for the junction box chosen you can use the two 3/4 inch knockouts that are across from each other on the box so the conduit entry is angled up and exit angled down which look fine. 8) I never use WAGO splices on receptacle branch circuits, I only use them with ceiling lighting circuits. 9) When modifying the GFCIs to fit in the metal face plate use a vice to hold your work you will have to take the ears off and cut off the threaded mount. 10) Use an automatic wire stripper to strip the THWN/THHN. Proper automatic strippers will not nick the strands. 11) Also test new Receptacles and GFCI Receptacles after installation with a dedicated branch circuit tester like the IDEAL 61-164 SureTest Circuit Analyzer (it will fully test GFCIs for current trip and trip time). As you can see the "workmanship" approach depends on who is doing the wiring and who the client is. My approach, as described above, and the approach in the video have nothing in common other than they both should pass inspection. The only real thing that I would do the same as in the video is have the branch circuit conduit come straight out from the side of the breaker box. This way the conduit run will not block any additional runs that need to go parallel.

Great Video. Before we moved into our new house, I had an electrician buddy install outlets on (2) 20 amp circuits on all 4 walls. He installed 12 outlets--on 2 GFCI breakers.

Scott, your panel should have mounted your garage service on thin strips of wood so there is an air gap behind it so that moisture from the all will not compromise the integrity of the panel. The usual way is to mount a couple strips of wood and then mount a piece of plywood to them thus giving you a solid foundation to mount your panel.

[@seephor]

Don't quote me but I believe EMT doesn't pass as a ground even though it's attached to the panel here in California. I believe the reason is that the conduit connections can come lose and some weather resistant connectors/couplers have plastic mating surfaces which breaks the bonding.

[@EverydayHomeRepairs]

I would agree that a local inspector, jurisdiction, or state could require a dedicated ground back to panel. Probably worth a call to see how the inspector is going to interpret code.

CA electrical code allows EMT as a grounding path. The raintight fittings have a plastic washer internally, but in no way do they disrupt the metal to metal contact between the conduit and the fitting. EMT fittings don't just magically come loose any more than ground screws magically come loose.

I always used a hammer drill for Tapcons. I don't believe it's the impact driver that strips them. I am sure they were already stripped. I met a low voltage guy. I have met many in my life but this guy is the best at what he does that I have ever seen. His advice was to stop using a hammer drill and use a regular drill with a masonry bit. He said since he stopped using a hammer drill he rarely has them strip. He also uses a regular drill for larger holes in masonry so he doesn't get the exit hole blow outs. We are in Florida so it's mostly block with stucco over it. The exit holes can make huge blowouts. I stripped many Tapcon holes in my life. Since not using the hammer drill I haven't had even one strip. If they do strip adding a stripped wire in the hole usually works to grab the Tapcon.

Some comments: First, gfci protection can be done at the breaker or receptacle. Pigtailing allows you to set up both receptacle locations like the one nearest the panel. This means my fat, lazy, behind can have them set up so there is a gfci at each receptacle location that functions on only that location. Should one be hidden or if the are further apart, the walk to reset is not far. As the pros know, section 90.4 allows your local building department (AHJ) to adjust or even ignore the nec rules. Section 334 nm cable, in 334. 10.(A). (1). restricts nm cables to dry locations. Basements may be dry or not depending on your ahj. There is information in the definitions section, but allows for some interpretation. 334.15 nm cable protection from physical damage. Has a section for basement installs. It calls for listed conduit with bushings. Conduit fill side note. Chapter 9 table 1 note 2 page 715 in the 2023 nec......if the conduit is for protection and not a completed conduit run, the fill requirements do not apply. (Not applicable here.) 358.30.(B). Emt supports. Requires a support within 3 ft of a box. Shown in this video between the 2 receptacle boxes, but not highlighted between the first box and the panel. Again, ahj may allow this. 250.118 still lists emt as an acceptable equipment grounding conductor. Fmc is also listed in this section with several restrictions. This indicates the metal boxes are grounded per. 314.4. 406.9(A). Receptacles in damp locations shall be weather-resistant type. Again, this is ahj on if the basement IS a damp location. 406.9(B). Metal face plates shall be grounded. 406.11. Connecting receptacle grounding terminal to box......see. 250.146. 250.146.(A).

I would not rely in the conduit set screws for adequate grounding since over time they will likely oxidize.

I thought it was okay to run only one piece of Romex inside a conduit but no more due to possible heat build up.

[@aurvaroy6670]

Well it's obviously easier to install a straight piece of conduit than to bend it several times. Also, no extra tools required. When it comes to NM cable, yes in some instances, depending on the jurisdiction of course, it is permissible to run a short section of NM inside a conduit to protect it from physical damage.

The thing I don't like is that the breaker panel is painted and your connector is creating an inconsistent grounding with the box depending on the hole size and if it is touching the metal properly. I'm no expert but I see that as a risk pretty substantial risk.

[@aurvaroy6670]

Well the GFI tripped so what's your point lol?

[@andydelle4509]

GFCI's don't need a ground to work. They sense an imbalance between the hot and neutral. If the imbalance exceeds 7-10ma, they trip as some of the supplied current is finding another return path, perhaps through you. That said I am not advocating not to use a ground wire and neither does the NEC except when replacing old two wire receptacles with a GFCI.

[@mabelisle]

For your argument to hold the GFCI would need to be before the conduit and not in it. Which means that the cables leading to the GFCI and the connection to it are not protected if the ground is not proper.

[@andydelle4509]

@@mabelisle I'm not following you here? The feed wires to any receptacle mounted GFCI are not GFCI protected. But they are still protected by the panel breaker. GFCIs are only required for certain receptacles in certain areas. Hard wired appliances such as air conditioner condensers and pool pumps do not require a GFCI as the are properly grounded with a permanent ground wire. Again, the ground terminal on a GFCI has nothing to do with it's GFCI functionality.

[@GigsVT]

@@andydelle4509 I think they are saying that there's a real world risk. If the conduit ground is broken at the panel fitting, and the before-the-GFCI hot contacts the metal conduit, you have a hot chassis situation that will not trip the GFCI and could give you a bad shock. He should have just used a ground wire, I think the majority of people would have.

[@richardyates1033]

Your metal boxes should be mounted on a moisture barrier, i.e. piece of wood. This keeps the boxes from rusting from the moisture that comes through those cinder blocks. That wall shows signs of moisture penetration and efflorescence already. Additionally, although you may not technically have to run a grounding conductor through that conduit, it is a good practice to do so. Over time, the set screws in the connectors and conduit will loosen and/or corrode losing the bonding effect for the ground path. I believe that running Romex in conduit may cause a possible overheating situation due to the temperature rating of the Romex and it being enclosed in conduit.

Although it was a UK style 220V system, I did have an issue with some work benches in Hong Kong where the faceplate securing screws loosened and there was a non-existent ground return.

Actually, better still run a ground wire back to the distribution board and then you are covered for any loose or corroded joints in the future.

[@doug8718]

Several points: 1) Wire is cheap, compared to safety...always run a grounding (green or bare) wire through the conduit and to outlets/switches. Your metal ground through the boxes/conduit depends on tight screws, etc. Screws will work loose over time, which will destroy your grounding conductor system. This is dangerous situation that could occur and you'd never know it until disaster strikes. Having a separate grounding conductor provides redundancy. If someone later does work and fails to re-tighten screws, you won't be in trouble. 2) You stated this is a 20Amp circuit, and you correctly used 12 gauge wire, yet you used 15 Amp outlets. You no longer have a 20Amp circuit. 3) While you did say you turned off the power to your sub-panel, it's always a good practice to actually put a meter on it to ENSURE the power is off. Taking 30 seconds of extra effort provides extra safety. This rules out any hint of something not going as planned when turning a breaker off (if it happens to be the wrong breaker). 4) I think you'll find that unless you're in a wet environment, using NM type cable (Romex) is perfectly fine inside a conduit, provided you follow any derating required by code.

[@jfowler702910]

I believe that you still need the ground wire pigtail from the grounding terminal on the device to a ground bonding screw inside the box. Yes you can use the metal conduit and boxes as the grounding BUT as soon as you remove that outlet cover with the outlets from the box, the cover as well as the outlets are no longer grounded. A pigtail ground from the devices to the box needs to be in place for when the outlet cover is removed. This allows for troubleshooting on live electrical circuits where all safeguards (i.e. grounds) are still intact on all metal equipment.

[@EfficientRVer]

You're right about no ground. You're wrong about no GFCI. While here, there is no ground available at the outlet (of a removed cover) for a GFCI tester to use to create a fault to ground (which will trip the GFCI) the GFCI will still trip if the current in the hot and neutral are not equal. For instance if some of the current returns via neutral and some returns through your body to a grounded water pipe you are touching. Basically, you confused whether a GFCI tester will trip the GFCI, with whether or not an actual ground fault at the actual outlet will trip the GFCI. They are not the same thing, specifically when the ground prong of the outlet the tester is plugged into, isn't grounded, so the tester fails to create a ground fault to test.

The GFCI does not give a pass on grounding requirements or integrity, it is a device and as such can be easily damaged or fail, resulting in loss of GF protection.

[@EverydayHomeRepairs]

If a hot conductor was to short against the box that would provide a path back to ground and trip the breaker. Specifically in this instance since the circuit is GFCI protected the GFCI breaker would trip before the breaker as a small difference between the hot and neutral would be detected. If there was no GFCI, and no path back to the panel for ground, and the hot conductor shorted then the conduit could ground through you when you touched it.

NEC Code requires you to strap within 3-feet of any box, panel, or termination point for that conduit run. So looks like you may need 2 straps there guy.

The ground wire provides a path for fault currents to safely return to ground, helping to protect against electrical shock and fire hazards. It is an important safety feature in case a hot wire comes in contact with any part of the metal box or conduit or if for some reason the connections become loose or broken. The type of grounding your doing is only for Equipment Grounding.
