How to Wire a Subpanel

[@briandonovan6546]

The very fact that building codes vary depending on the municipality is why I avoid pulling permits on anything. If the inspectors cannot even agree from city to city, I will do it the way that I see working the best/safest and save the permit fees. And yeah, I am a licensed builder by trade haha

[@newday8172]

Why would you use a white( neutral) wire in combination with a black( hot) wire for a double pole breaker? Shouldn't it be 3 wire,red and black to double pole white to neutral and ground to ground?

[@TimWilborne]

Not all equipment requires a neutral. In many cases, only 2 legs of 120VAC and a ground are required.

[@newday8172]

@Tim Wilborne appreciate your answer. Just a quick question. When wiring a sub panel, it should not be wired were the ground and neutral are bonded? What type of panel is that. Does it come not bonded?

[@TimWilborne]

@@newday8172 That could vary depending on where you are located but for the most part they are only bonded at the main panel, they are separate at sub panels.

I appreciate your mention of the ground rod installation. I believe when my place was done, I may have had one of those vendors that cut the rod short. I'm running into bleed over issues with one circuit on a 100-amp panel and have a few suspicions.

[@ericwotton2046]

I'm curious what you mean by bleed over issues? Could you elaborate?

[@StoicThrower]

@@ericwotton2046 Voltage is being split between the neutral and the ground wire without tripping the breaker.

[@ericwotton2046]

@@StoicThrower Interesting, is it just one circuit causing the issue? Your panels are all networked properly with grounds and neutrals separated back to the main service panel (where they combine.) You might have a ground fault within that circuit either an appliance or improper wiring in the brach wiring. A ground rod really wouldnt effect this much unless multiple transformer are involved.

[@StoicThrower]

@@ericwotton2046 yep. One circuit. Checked it all. Replaced every receptacle. Wired correctly. Nothing was plugged in. Never did find a definitive reason for it. Ran a new 20 amp circuit with no drama.

[@seanvandermolen7287]

i don't think that grounding rod should have been installed in the first place. The grounding bond should only be at the mains panel. By adding another ground rod, you can potentially create another path back to source through earth that would cause the issue you're talking about. The bleed is current on ground where it should not be.

[@bsmith8564]

You exceeded code on a couple things, good for you. Ground rods only need 6 feet of separation and NMB needs strapping within 12 inches from the box not 6. I could not tell if the grounding electrode was continuous between ground rods as is required due to ground rod clamps are rated for one conductor only.

[@Sharpshooter44024]

I have a question. I installed a whole house ATS. Im connecting to the breaker which has just become a sub panel. I assume that i have to now install a seperate ground terminal bar in the old breaker on bother sides of the lines. Now I then take a wire from from both ground bars and run it into the ATS using two wires 3 AWG (copper) going to ATS ? I am to move the earth ground from the old breaker over to the ATS. The neutral is already connected through the transfer switch block over to the sub panel. The changes are only on the ground ? The breaker is 200 Amp in ATS and old main breaker.

[@TimWilborne]

Improper grounding not only can damage the generator, it can get you hurt. Time to call an electrician. It will be dollars well spent and some localities have different specifics on this so no one here can give you sound advice.

Great Great Great video man. seriously I watch a lot of videos on different topics. You nailed this one!

[@TimWilborne]

Awesome! Thank you!

[@aammiranda]

Great video. Why aren’t the neutral and ground bonded in a sub panel?

[@TimWilborne]

You need to check your local electrical codes but here, they can only be bonded in one place, the main panel.

[@usmarinekenny]

They aren’t bonded in a subpanel to eliminate a parallel path of current back to the panel on the ground and neutral. Since the white neutral is the return for current to flow back to the source, if you were to bond the ground to it, it would then share a path with the neutral and share the current flowing back and becomes a current carrying conductor which it was not meant to do. The ground is only suppose to carry current in a fault condition ie short circuit or ground fault. This is why they are separated. I hope that helps and was understandable.

So heres what we have going on. We have a main pole that has 200 amp service to it. We have a shed that is about 350 to 400 feet away and we'd like to install a sub panel to feed an A.C. and a fridge.

Does this sound like the right set up? Also would I need to worry about voltage drop or would this set up enable The A.C. and fridge to run without fault even with voltage drop. I have literally just started to learn about all this in the last week. Treat me like a toddler when answering please. haha

Okay, this was super helpful. We're running a sub panel into our shed to run an ice machine and a time clock, and this video helped with some of our questions, but everything inside the shed will be 120v, so do you have a video of how you connect this inside the main panel to feed the sub panel? Inside the shed will only be an ice machine, a time clock, and a couple outlets and 2 led ceiling lights. All 110, so we wouldn't need 240 coming into the shed. We'll have a separate breaker in the main panel for this shed, but how do we connect that breaker for 120v and 100 amps? The 100 amps is the bosses decision.

No. In my locality, sub panels that are in separate buildings must have both a ground from the main panel and a ground rod. You need to check your local laws and codes.

I remember being new at a place and how much time it took to mess around with the wiring and to make it look good, etc. The tasks per se weren't difficult even though I'd never set my foot there before let alone worked with those things in my life. Once you knew exactly what to do and how to do it right it was okay. The trickiest might've been reading the charts correctly, like connecting certain components on to the boards. Anyway, to cut a long story short, the job lasted for 2 months when I had to quit. I used too much time in someone's opinion. In MY opinion, kicking someone out after 2 months is ludicrous.

I'm not a controls guy, I worked as design engineer for contractors and consultant from 1983-2018. Since you mentioned it in your video, what is your perceived purpose for the one or two ground rods in the electrical system? Not all sub-panels get them as stated, only if in a different building. Respectfully, Kevin

[@TimWilborne]

Hi Kevin. As far as one vs two ground rods, NEC 250.56 requires a second ground rod if the ground has a resistance of 25 ohms or more. I don't want to get into the argument of whether all sub panels should have grounds or not.

[@KevinCoop1]

Tim Wilborne I totally agree with you on higher than 25 ohms requires second rod. In my code classes, it was suggested that it is cheaper to just drive two and forget it. Testing time would be higher cost than installing the second rod. What I meant by not all sub panels need ground rods, keeping this conversation in dwelling units, if you have a 200 amp main service panel in a dwelling, it is required to have all available grounding electrodes connected to it. Now put a 100 ampere sub panel in the middle of the dwelling next to the kitchen. No ground electrodes are required. Put another 60amp sub panel in a detached garage, a connection to grounding electrode is required. Note: this requirement of ground electrodes in separate buildings flip flopped back and forth several times between 1981 and 2005 NEC. Not looking for any arguments. Hope this clarifies my comment. Respectfully, Kevin

[@ericwotton2046]

@@KevinCoop1 I beleive the main purpose of the ground rods in a simple dwelling is for lighting protection. Thats why a sub-panel in an annex building needs a ground rod. It gives a bath for nuisance current to bleed off the system. It also helps the whole electrical system have a reference to work with, one common ground. This becomes important in large buildings with multiple tranformers and sensitive equipment.

Thank you for a very well done video. I’m putting in a sub panel for a basement apartment. It will have a dryer and an electric stove so I’m going to have a sub panel. My question is related to the ground rod. I initially was going to put my panel on an inside wall but that would mean I would need to run the ground right up through the ceiling and then down to the outside. Can I assume that’s not ideal and I should put the panel on an outside wall? Also, can ground rods be drilled through the concrete slab and into the ground underneath the slab? I’m thinking no but I thought I would check.

[@TimWilborne]

Definitely want to check with local codes on the ground rod. At least here you could have it one an inside wall and run the ground to the nearest outside wall. I have no idea on the concrete slab, never ran into that situation. I would consult a local electrician, you'll be dollars ahead.

[@RighttothePointDIY]

Tim Wilborne Thanks Tim. I will do that.

[@dannycalk8051]

When you're past your outside main you do not run a ground from the panel to the outside, if you do you're defeating your purpose of having a ground path back to the main panel where the power supply enters the residence, if you ask an electrician be sure and ask someone who knows the code and has experience with installing sub-panels.

Not all 240V arc welders are the same and not all 240V air compressors are the same.

I was going to tell you to stay in your lane, but you're already there. Looks like you've done this a time or two. :) I'm not saying that I'm an old electrician, but I still remember doing new installations using TW wire (and thank your lucky stars if you haven't had to pull that garbage into a conduit - however, it does do a great job of pointing out if you haven't reamed your conduit properly). I was taught to strip the sheathing off of the Romex cable prior to running it into the panel, and it does make for a little bit tidier of a job. But that's really just how my Journeyman beat it into me, rather than any personal preference (my personal preference being not to be beaten anymore than I had to be). Anymore, I would just go ahead and run the second ground rod and be done with it. Copper water lines into the house is a thing of the past. And to anyone who wants to do their own wiring, I would suggest visiting a construction site under the guise of being potential buyers and look around to see how the "AHJ" (Authority Having Jurisdiction) wants it done. But be fully prepared to have your job turned down even if you have done your wiring the exact same way as the pros. It's just a homeowner thing, and complaining to the AHJ is only going to make it worse. Oh, and: 1) Bring donuts and coffee. 2) Show up just before first break. 3) Keep a sharp eye out for the boss, and if he/she is not there, chat up one of the electricians to see if they would be interested in helping you out. Keep in mind that some shops treat "side work" as a firing offense, which is why you have to make sure that the boss is elsewhere. 4) Don't be a jerk. Pay in cash. And in slow times like these, the AHJ will turn down everyone's jobs pretty regularly to keep his inspector buddies from getting laid off. As an electrician, shop owner or otherwise, it is in your best interest to pay this bribe since what you don't want to see is your normal inspectors having to move on and then you have to break in a new one.

[@MrWaalkman]

@@TimWilborne LOL! The programming port was where my journeyman was going to put his boot if I whined about running the jackhammer. :) That really was the installation from heck. We had a heavy rain the day before it was to be inspected (so it was still open for inspection), and the ditch where we had our two 4" PVC runs got completely backfilled with sand. The conduits, being empty, naturally rose to the top of the ditch and were sticking out every fifty feet or so. So we had to hand dig the ditch again, this time being careful not to break our conduits. I was happy to see that run get finished. Pulling the wire wasn't too bad, we used a capstan puller, and each of us young bucks got to pull the wire off of one spool each. I've been involved in worse pulls... :) Another really bad ditch was one that fed a pad mount transformer and went down the center of an alley to the vault. It had eight "known" crossings. A combination of water, telephone, cable TV, power, as well as a sewage line below all of it. It also had one "unknown" crossing which the city neglected to locate for us, and we naturally found it, and removed it, for them. It was an abandoned water line that the city had simply capped off rather than removing. We ripped the unmarked line right out of its corporation (what the city water crew called the connection between the main and the smaller water line). Ever see how much water can come out of a 3/4" hole at 800 PSI? It's prodigious... The city tried to blame us, claiming that we were responsible for items that they had missed. Right. Our company wasn't having any of that nonsense, and the city got to fix and pay for the damage. It wouldn't have been as bad but the corporation was mounted at about twenty degrees from horizontal and the water pressure undercut a large portion of the parking lot to an attorney's office which collapsed into the ditch. Of course the ditch filled up in no time at all, and that little hole was now providing the center of Colorado Springs with a decent sized stream for the kids to play in. So there's always an upside. And this was also one of those runs that had to be encased in concrete, so we had that to deal with as well once the carnage got cleaned up. We also had to run a ditch for our power behind a strip mall that we were wiring. We had contracted a guy to cut the trench with his Ditch Witch. The only located line was a telephone line marked for us by Ma Bell. As the dutiful apprentice, I offered to hand dig that section out for him. He said "Don't bother, I can feel the cable with my stinger". Nonetheless I went to the truck to get a shovel, but by the time that I had gotten back the stinger on the Ditch Witch was wrapped up in an array of multicolor wires from the cable. Kinda reminded me of a Christmas tree... He had hit a one thousand pair cable that carried the long distance calls from Colorado Springs to Denver. As well as being used for communications to and from Norad. So yeah, not a good cable to have an accident with... Ma Bell (Mountain Bell) employees started popping up like popcorn all over the place. They were easy to spot, white shirts, black slacks, and all with unpleasant looks on their faces. The downtime was $1,000 a minute. The bonding company refused to cover the damage, citing "stupidity". That was the end of his company, and much of his personal possessions. My boss did a back door deal with him to buy his Ditch Witch so that he could have a bit of cash to live off of until he could sell his house to cover (a portion of) the damages. Ma Bell wasn't taking any prisoners on this one. He offered to help cut a new ditch, which had to go thirty or forty feet in both directions from the damaged spot (you have to remove a large section because the wire insulation gets ruined closer to the cut). The Ma Bell splicers said "Thanks, but you've done enough". The first thing that the splicers did when they had their new ditch dug, was to dig out "thrones" for themselves in the wall of the ditch to provide a place for them to sit while they made their splice. Pretty obvious to me that they were going to be there for awhile. It took them thirty hours to splice in a new section.

I have a sub panel in a garage, fed by 4 wires (2 hot, neutral, and ground). The neutral bar in the sub panel is not bonded to ground and I believe/read it should NEVER be bonded in a sub panel. I have 3 things attached to the sub panel- a three prong outlet for a compressor, an air conditioner (3 wire), and an electric garage heater (3 wire). All are 240v (or 220?). I do not have a separate grounding rod for the sub panel. The sub is 4 feet from the main panel and I added a grounding bar to the sub panel. *****The question is... should the ground for each of the 3 connections be connected to the ground bar or neutral bar in the sub panel? I cannot find the answer anywhere!!! Thanks!

[@TimWilborne]

Ground should always be connected to ground. Ground is a non current carrying conductor. Neutral is a current carrying conductor. Never mix them up.

Hello. I currently have a 40amp sub panel and need to accommodate an extra 60amps in it. In the 40amp sub panel there is a 15 amp and a 30amp. What size breaker do I need in the main?

[@blackseabrew]

I'm and automation engineer who live on a farm. Been upgrading wiring and panels. The most recent of which was installed almost 50 years ago when I was three. One question...why does the ground rod need to be at least 6' from the panel? As in what's the real purpose of the distance? Not the NEC answer.

[@TimWilborne]

Where does it say that in NEC code? It is suppose to be a few feet from the structure, I assume so it is truly grounded and not up against the footers of the building and if you have two ground rods then they must be 6' apart, but I've never heard that they have to be 6' from the panel.

Hello Tim So I would like to know if it legal and not against the code to come out from a 200A 208y/120v 3phase panel to a 100A 208y/120 single phase?

[@TimWilborne]

Yes it is legal but reach out to a local Electrician so you can get the details right

[@mipuntodevista3988]

Question: Is it ok to add a subpanel to the main panel even so the main panel does not have a main breaker? Hope my question makes sense. Thanks in advance!

[@wiley0714]

Your main panel would have a main breaker. Then in your main panel you would install another breaker which would send power to your sub panel. If you put in a 200 amp panel you would have two 100 amp breakers. On one leg of that panel you could install let's say a 50 amp breaker and then run power from that into a subpanel.

[@robertknull456]

I need to add more circuits. I have a 100 amp fuse box and I would like to add a sub panel with about 16 to 24 circuits. Can I add a sub panel rated for 125 amps to a 100 amp main panel?

[@francoisdesmarquis8548]

Need an upgrade to 200 amp

[@jspeed51]

I liked the Napoleon Dynamite dancer in the last scene there.

[@masterroaster1109]

So I'm running a 12/2 to a 20 amp in my sub, do I connect white and black to the breaker screw and the ground bar?

[@masterroaster1109]

And the ground to the ground bar?

[@TimWilborne]

No. You should consult an electrician before proceeding. It will be a small price to make sure you don't burn anything up.

Don’t quit your day job there buddy…. Oh wait, nevermind. Jk lol. Enjoyed this, good information and well put together. Thanks for sharing! Btw that panel you flashed on the screen looked killer!!🤩

[@TimWilborne]

Haha, I know to stay in my lane. That panel that I showed was artwork and that takes many years of practice.

[@ozzmann3217]

What do I do if I have a full main breaker box and want to add a sub panel ? Is there a Way to grab one of my other breakers for the sub panel? I’m not going to use this as my only source just want to see if my project is even possible I basically have a full breaker and the original basement outlet and so many others outlets and lights are on one single 15 amp breaker so I wanted to add a circuit for basement for my workshop and sub panel seems the only choice i have

[@traceyfrink6574]

That bit is called an AUGER BIT

[@TimWilborne]

I can't recall, did I call it something different in the video?

[@pramodkarande9855]

What is gfci outlet

[@TimWilborne]

Gound Fault Circuit Interrupter... Depending on where you are located they may be referred to as a Residual Current Device.

[@LightWalker03]

Thank you much

[@TimWilborne]

You are very welcome

[@adamwagner7105]

Not bad, but still need to watch another video to pull the power and run the conduit. Not a full subpanel install video. Basic "wire any panel" with the exception of the ground bar being different in a sub panel.

[@x7warrior735]

Excelent Job ⭐⭐⭐⭐⭐

[@TimWilborne]

Many thanks

[@wiley0714]

Ya lost me. If I had a double pole breaker. That means I have one breaker that has two outputs. I would put my black wire into one of them. And then I would put my red wire into the other pole. Let's say I had 12 three wire. I would have a bear ground wire, a red wire and a black wire, and the white wire would be the neutral wire. I don't understand why you would put a white wire which is generally a neutral wire into your breaker?

[@TimWilborne]

Not all 220VAC requires a neutral. For example this is a common dryer plug that you would use a 2 w/ ground...black, white, ground. amzn.to/3SJ7GpD

[@classicv8dude268]

I’m using white wire for 20 amp breakers

[@Montanafield]

When running the feed from main panel to sub panel is the conduit required if inside wall?

[@bradleycoles8273]

what size subpanel are you using in the video?

[@marlpierre8985]

100

[@marlpierre8985]

100

[@Rico702Vegas]

So 120V + 120V = 220?? Man I need more math lessons lmfao. You are definitely not an electrician.

Just the basics, not the art of doing it like an everyday electrician :)

[@joro18d93]

You didn’t explain wiring the right side as you said you would.

[@TimWilborne]

Seems like I did, what parts was unclear?

[@jakearmstrong4563]

I don’t mean to be that guy I just would absolutely never use that bit it is just too comically large to even justify picking up instead of a paddle bit. Seriously a whole set of diablos is like $20

[@TimWilborne]

You mean spade bits? Nah, I can't agree with you on that one. An auger bit takes less effort. Let the rolls do the work. And I have shorter ones for tight spaces but this one is much easier on the body.
