WORKSHOP RENOVATION 16 : DIY Shop Electrical Basics w/ Conduit Bending

[@charlesemmer8856]

Another good practice is to label each of the receptacles with the circuit breaker number (from the panel schedule).

[@craftedworkshop]

Definitely planning to do that after painting! Good tip!

[@jaggederest]

Hospital standard is to label the outlet with the panel number and the circuit number. Especially when you have a bunch of panels it's a life saver (literally, in the case of life support equipment). I don't know if that's just an institutional thing but it made sense to me. P7C15 etc

I just did a quad box last week and found the tabs you break off of the face plate is actually a nut to be used with screws on the outlet, this was a great idea to me as i dont always have the correct nuts and screws on hand.

as a german electrician, american electric never cease to amaze me. this is so unusual for me i have to remind me that it's not neccessarily bad. also i love the tubes

[@EnigmaPSU]

Just a helpful FYI to save you some money. At about the 11:25 point in the video you show breaking off the small tabs on the metal faceplate and removing the screws from the GFCI outlets. Then using #8 screws and nuts to attach the outlet to the faceplate. Actually, those small tabs you broke off of the faceplate are tapped to act as nuts so that you can reuse the screws you removed from the outlet in order to attach the outlets to the faceplate.

[@craftedworkshop]

Thanks for that, will make adding the rest of the 120V outlets easier!

[@kraken509]

I do dual duplexes as well but put 2 circuits in each box. All left duplexes are one circuit and all right are another. One thing to consider next time is showing the deburring of the conduit after cutting it.

You guys are lucky to be able to do this work for yourself. Down here in Australia you need to be a fully qualified electrician to do any electrical work. We also have different power available to us, all domestic single-phase outlets are 240 volt & commercial 3 phase is 415 volts. Billy J... Queensland, Australia

An alternative to box offsets on EMT for those who are not comfortable with bending is to use back straps or spacers at the strap locations. This aligns the EMT with the KO’s in the 1900 boxes. Another benefit is les dust settles into the space where the EMT runs along the wall. Just another option.

[@TxStang]

They also sell offset fittings about 2" long that attach to the boxes and jog down to the EMT . For 2 bucks each they make it go fast and simple and keep the EMT close to the wall .

Looks great! Love the deeper boxes with two circuits each. Good call on the dedicated ground and separate colors. Strange that there would be 3-phase power into a sub panel, do you have true 3-phase coming into the building?

Looking forward to the next video

[@KevinCoop1]

Very well done and correct video! Congratulations. I’m not sure why you showed a dwelling unit rule in the NEC when discussing GFCI. They have been required a long time in non dwelling locations. You could have also wired all those box locations with two circuits at each. Left one and right two. Slightly more flexible.

[@kenr2412]

The gray neutral is for 277 volt circuit. You need to use white for 120 volt circuits. You could have used one neutral to share with both circuits. If you share a neutral with two circuits, you also need to have a two pool breaker or a handle tie to turn off both at the same time. Don't forget to get an electrical permit and have your work inspected. You'll make your insurance agent happy.

[@huntermccubbins8954]

In a commercial buildings it better for the ground on the outlet to be facing up incase something plugged is hanging out just a little. If something metal falls on it it will hit the ground instead of the hot and neutral. Most new construction commercial buildings spec it in the plans.

[@macxgeek]

I know this is true in hospitals but I would still do the way he did because I think it look upside down otherwise

[@chanceltw]

The code is not applied retroactively. Once the 2020 (or newer) NEC goes into effect in your area, you won't be required to add those GFCI breakers to your existing 240V circuits if you don't want to.

[@Meyerwoodworks]

I added a 125A sub-panel to my garage/shop. Two things I wish I did differently for anyone who is thinking about doing the same: 1) Go bigger on the conduit than you think. When doing 220, each outlet has to be a dedicated circuit, so you have a LOT of wires to pull. The conduit quickly fills up and it makes it difficult to pull. 2) I used 12awg THHN because I only needed 20A outlets, until I needed 30A.... now I wish I would have just ran all 10awg. If I would have ran all 10awg, I could have swapped one of the outlet 20A plugs for a 30A instead of having to run all new conduit/wire for ONE 30A tool.

[@Jraksdhs]

No reason each outlet has to be dedicated unless you plan on running multiple machines at once. I recent built my shop with single and three phase via a large rotary. I have 4 50 amp welding outlets around my shop depending on what I’m doing. I’ll never be welding at more than one location and I’m the only person who will ever be working in there. Just plan accordingly and you’ll be fine.

[@Meyerwoodworks]

@@Jraksdhs I guess if you're by yourself you are fine, but I still wouldn't do it for the next person. I work with another person and often run the dust collector, CNC, vac table, laser and other tools all at the same time, maxing about 120A at one time (tool rated, not actual measured draw).

[@LilahLily87]

Wow, so I just had to have a whole bunch of electrical work done in my house. They didn’t have enough electricity coming into the house and so they had to redo my entire electrical. They had to bring in bigger wires off the road and they had to replace my breaker box in order to bring it up to code. Apparently in Knoxville Tennessee, not far away from you you have to have arc fault breakers to be in code and let me tell you those are expensive!

[@idontthinkso666]

Yes, the arc fault breakers are becoming required everywhere now. They had to install them in our new addition. I had them swapped out after the final inspection. Why? They are hyper-sensitive. If you use a tool with a high starting amperage (miter saw) they nuisance trip.

[@surferdude642]

I've seen a few videos now of non electricians doing similar work, usually it's easy to find mistakes due to ignorance or non ignorance, but just being cheap or lazy. Not here, you look like you know what you're doing, and imo the workmanship is top quality and very professional. I'm assuming that the THHN wires and the mc cable are 12AWG. I did something similar, albeit at a smaller scale in my garage just to increase lighting and receptacle location convenience. You said that every other box is on a different circuit, but the first one has both circuits, one GFCI for each, and I think that's fine, just wanted to clarify. I would prefer to use the formed or molded metal boxes with rounded corners instead of those sharp edged ones. Otherwise, great job.

[@IWasNoah]

it’s easy to find mistakes so many code violatiovs

[@EPortillo5000]

As always great video, just an observation, I usually see the installers put the conduit on the floor and put force on the handle of the bender, seems to be easier that way.

A note on grounding modern tools and equipment, particularly if it has electronics involved- electronic circuits can easily fault if they lose positive contact with a solid ground. Anything from a service interruption to an expensive tool repair can result.

I am a limited energy electrician here where I live when running conduit you are supposed to have a conduit strap within a foot of the box and one every 10 feet of pipe. Is that not a thing there ? It was NEC code last time I had to do code update class.

[@PLATTpanthers51]

It’s 3ft within a box/coupling and 10ft after that

[@stargazer7644]

I'm curious to see how long those GFCI's last before you rip them out. My inductive power tools trip them constantly.

[@ericfraser7543]

5:28 I believe it is code for you to share the neutral wire for those two 120V circuits so long as the circuits were on opposing phases. I.E. you would install a double breaker and wire the hots for each outlet on each side of the braker and the neutral is shared. Each circuit would then be ensured to be on an opposing phase which 180 degrees out of phase from each other. That would ensure that the common neutral wire could never be overloaded with the maximum 20A current at any moment in time, in fact if current were drawn on both circuits alternating current on the neutral would cancel each other because they are 180 deg out of phase with each other. I am not an electrician, so you might want to check with your local codes first but it might save you some wire.

[@kraken509]

This is correct but with short runs it’s just as easy to run 2. Box fill and conduit fill would be a main driver for me to share a neutral in a small install like this.

[@danediz]

its 3 phase, so can you do 2 pole mwbc? even if you do, you have to scrap the gfi right??

[@Nikolaos34]

Unfortunately 240V GFCI requirements are starting to catch up, garage circuits are first on the list - at least in my local jurisdiction. And 'garage' is fairly interchangeable with any interior space with a concrete floor. _You are the ground_ when standing on concrete. So you are correct to install GFCIs in your shop. And yea man they are not cheap. And that's not even scratching the surface of 2017+ NEC requirements. Between GFCI, AFCI, CAFCI, and dual function - manufacturers are raking it in right now. The real kicker, is that standard breakers have a recommended lifespan of 30-50 years. These new GFCI / AFCI breakers are only rated for about 15 years before replacement. Funny story, there's a lady who flips houses in a county next to us, all of the inspectors know about her. She passes the final inspection on a remodel, then rips all the AFCI breakers out and uses them on the next one. Replacing them with regular breakers once the inspection is clear. I honestly don't blame her, these new breakers are terribly sensitive despite being life saving devices.

Question: couldn’t you use the same white neutral wire for both circuits if the breakers were fed from opposite legs of the main? I’m thinking the return currents in the neutral would subtract from each other which would make separate neutrals unnecessary. Or am I missing something?

[@noahboyd2186]

It can be used in that orientation (for bending 90 degree bends or kicks usually) and used with the handle on the ground and the curved part (the shoe) in the air for other tasks where bending with the shoe on the ground is less convenient, like bending offsets. Personally (apprentice electrician here) I sometimes did my first bend in the air and my second bend on the ground so I could use a level to ensure the offset was even.

One of the nicest jobs I have seen from a non-electrician. You obviously did your research. Good job explaining the Delta-High-Leg Panel. I am one of those Electricians that always uses a ground wire in my conduit. The conduit after it ages and has been altered over the years, becomes very unreliable as an equipment grounding conductor, in my opinion. I have seen evidence of this many times in my career(loose fittings, corrosion, paint, grime, etc). P.s. those little tabs you broke off the metal cover plates are to be used as nuts to hold the devices. Thanks, Russ-Electrician from Oregon.

When did NEC change to start requiring a separate ground wire inside EMT rather than just bonding the EMT to use the conduit run as a ground path? Asking because I have a similar project I’m starting and I can’t find any references to a code change that disallows using the conduit as a ground path. Edit: This comment was in reference to the statements at 2:50 around the ground wire between the main and subpanels. I suppose it would make sense to treat that separately in code compared to the receptacle grounding you do address later in the video, and which is more applicable to my own projects. Would still love to have a reference.

[@GibClark]

Doesn't in between receptacles, codes a minimum, good quality work requires it. Conduit becomes corroded, gets beat around, comes loose over time. Good ground path is essential.

[@rusty_restorations36]

Dedicated ground is not required in my area either. However i experienced an energized conduit due to a piece of equipment that failed to ground. leakage voltage that would tickle but, nothing harmful. Still enough to make me run a dedicated ground whenever possible.

It's just good practice to have a dedicated ground. In some areas even a sub panel requires a dedicated grounding rod as well, not just a ground back to the main panel.

200A 😂 most places in Europe has 3 phase supply (even domestic) and 230/400V so we don’t need that many amps. And we don’t need so thick wires. A common house in Denmark has 25/35A main fuses typically 😁

[@JockeData]

@@johnowens178 You have a separate main service breaker and GFCI here. In older buildings where GFCI was first beeing used, you only had one GFCI for the whole breakerbox. So if it tripped, your whole house would go dark. Today you usually section them up, so lights go on one, and outlets on one. But id still say you dont have more then maybe four GFCIs for a standard house.

[@w2ttsy670]

Similar to Australia. You have two options: RCD + up to 3 same purpose MCBs for a block of circuits or RCBO (which is RCD and MCB in one) for each circuit. There is an option to get an outlet with an RCD attached if it’s not feasible to protect at the switch board. Also noteworthy is that we split lighting and general power onto different circuits rather than sharing the same wiring for both like in the US.
