[@relianceelectric8501]

great content short and sweet, to the point !

[@mathman0101]

So the reasoning behind all of this is to ensure a low impedance overcurrent ground fault loop path as structure being further from the house could add to impedance result in inefficient or ineffective operation of overcurrent or fault current protection devices (breakers/fuses). Measuring ground earth resistance using a 3-wire fall of potential method is a good way to ensure you get down to less than 25 ohms of resistance. Two ground rods usually gets you there to 25 ohms or less but soil conditions differ across the US. If your not testing your guessing. With a sub panel in a outbuilding there are additional issues to consider like selective coordination of protective devices at the sub panel and main panel. Good set of videos to raise this issue. If there was a metal water pipe connected between the two buildings that would also need to be bonded with the GES at the outbuilding.

Main merge/ Sub separate easiest way to remember

[@davidpatrick1813]

man oh man, this is clear and helpful. I am installing a Victron charger/inverter in the out building and didn't know to use a ground rod connection or not.. the "ground loop" fear in ignorance is the issue. When the AC power drops from the Victron input, it automatically connects the ground and neutral ... no ac only battery to inverter and then AC out...

[@Just_An_Idea_For_Consideration]

QUESTIONS: If instead of the pole transformer from the electric company grid as the source, we had a completely OFF GRID solar outbuilding as the originating source of power (say 500 feet from the main panel). 1) Do we treat the outbuilding as if it were the grid? 2) Do we create a neutral ground bond in the outbuilding - as the source of power is generated there? 3) Do we create a neutral ground bond at the Main Service Panel? 4) if there is a NG bond at the power producing outbuilding - and a NG bond at the Main Service Panel - if a short circuit occurs - a) WILL IT TRIP THE BREAKER in the Main Service Panel? b) will it trip the breaker in the outbuilding that feeds the main service panel? c) should each building have their own ground rods? Please advise. Your channel provides great knowledge. Thank you

[@cae2024]

Hello. Glad I found your KZbin channel. I am getting ready to run power to my new metal building from the meter on the back side of my house which is a 200 service. I have been told several things from different people. The total run underground in 1.5” pvc conduit will be 120’. I want to use a 100 amp breaker out there to feed everything. I do not need anything major because I am just running LED lights, a industrial ceiling fan and some outlets. Not running a big air compressor or anything like that. So do I have to run the 3 or 4 wire out to it? Also would it be a number 2 or 4 wire? Thanks for any input

[@donnymccaleb5135]

Do you still need to put a grounding rod at the attached garage outside?

[@karamwaisy1063]

thank you

[@SilverCymbal]

I have an older building that is fully detached, its about 20 years old. It has only 3 feeder wires and its own ground rod. Was the code different back then that would have made this ok? Thank you in advance

[@lukeroberts9944]

Why do we need to run a equipment grounding conductor? Couldn’t we just use the neutral as a ground? I know code requires but why does it?

[@ElectricalCodeCoach]

Great question, we must establish a grounding electrode system for surge and lightning purposes.

[@danielhass4812]

Can you explain why SER cable can’t be buried? I’ve read that it is because the equipment ground is not insulated, but I’m also pretty sure code allows uninsulated equipment ground to be buried.

[@kenfrederick8218]

Thank you for video! I have a question I hope you will answer. I ran triplex(4ga alum) in 1.25” conduit out to shed I’m building with 60 amp box. Didn’t know about required 4th ground wire, the 1.25” conduit isn’t huge so wondering what gauge the 4th grounding wire needs to be. Thanks much, Ken

Theres all kinds

[@vince6829]

Your video answered some big questions I had. Thank you. Here is another question- If a detached garage has a sub panel that is fed overhead by three wires (two hots and a neutral but no grounding wire) from the main panel, can a separate grounding wire be run underground from the main panel to the sub panel to satisfy the four wire requirement?

[@paultiefel515]

This is great stuff! Thank you. Questions: Can electric cable (#6/3) be run above the soffit, in the eave of a house, to a drop point and then through conduit buried to reach a separate structure? Would conduit have to be used in the eave run?

[@ElectricalCodeCoach]

Great question! You cannot use 6/3 NM outside at all.

[@andrewclark4369]

whats the difference between a 3 wire 220v outlet and a 4 wire outlet?

[@Holop88]

I'm guessing 3 wire is without neutral and 4 wire is with neutral

[@changingmatrix8687]

So this means you can't bury a triplex aluminum wire feed to a detached building subpanel (because its only 3 wires and not 4)?

[@ElectricalCodeCoach]

Correct

[@changingmatrix8687]

@@ElectricalCodeCoach I'm sorry. I'm female and trying really hard to figure this out. Should I then use 2-2-2-4 THHN copper from an outdoor main breaker in 2" conduit to a subpanel in a big shed? Its a 76' run. (I'm attaching a 100amp breaker panel in the shed with 2 ground rods, because I know I can't use a lug panel in a detached building). Thank you.

[@nynv94]

So install a grounding rod at structure and ground that to the physical sub-panel housing and then the ground wire from the main panel goes to an unbonded ground bar in the sub-panel and the neutrals go to an unbonded neutral bar in subpanel? Is that correct?

[@paulg7392]

hello I have a question. When I am running 3 wires to garage through over head mast on both sides. Then I install a grounding plate in the garage side, Do I have to bond together the neutral and the goung wire in the box installed in garage? Pleas let me know

[@bman6502]

Based on a lot of questions being asked here, I’m becoming a much stronger advocate of building inspections..

[@RedPillLife1966]

Does this also go for pre-existing detached Garage?. Its already wired 3 wire ( 2 hot and one braided Neutral ). It is attached to the external main breaker panel on the house by a double pole 50 amp breaker. Everything in the garage works just fine. Looking to replace the sub panel. It's pull switch type with paper fuses.

[@ElectricalCodeCoach]

Have you seen my video on When and Why to Separate Grounds and Neutrals kzbin.info/www/bejne/jXSap2yNicRmqrs

[@publicmedia7858]

why not create a new ground close to the new structure ?? why running long span of ground cable to the ground source. Ground is not single or 3 phase power that need to be synchronize with source main supply.

[@ElectricalCodeCoach]

That's a good question, that's just how the NEC has it set up*

[@thomasmarable6818]

Because of ground faults its to insure it goes back to source through your single bond point. The grounding electrode is more to get the lighten back to earth as quick as possible

[@Ringele5574]

My question: I'm putting in 50 amp service in my steel shop. I confused if I Ned a separate grounding rod for this subpanel. If so, does it connect to the structure, the can and the separate ground bar? I've spent several days trying to find this information on Google and KZbin without a clear answer.

[@crazysquirrel9425]

You presume that you are going from panel to panel. What about going from an existing outlet circuit in the house to the garage? Mine is a 3-wire for turning on/off the lights from either. Outlets in garage are tied in and grounded by their own existing ground rod. No ground wire between the house and garage. Works PERFECTLY with a GFCI. Needed the GFCI for a battery charger and once in a great while a drill. There was never a sub panel in the garage. Costs far too much to pay to upgrade the garage, wiring, and main service panel. All for ONE stinking outlet....

[@jrm97001]

When feeding 2 phases to the outbuilding sub panel, is a disconnect required? Does it have to be at the outbuilding or can it be at the main building? Would the breaker at the main panel that feeds the subpanel qualify as the disconnect?

[@ryananthony4840]

Main panel. Sub panels usually don't have main breakers however, it might be more convenient to have a main shutoff in the building

[@tedlahm5740]

Sub Panel treatment as usual nothing new here. MUST have grounding system rods etc. if installing a panel. Even though the green screw is REMOVED isolating the grounds and neutrals STILL MUST ground the can to the equipment ground and all the outlets in that building.
