I'd use a 4/0-4/0-2/0-4 Mobile Home Feeder cable for this job. Given that you aren't going to be pushing a full 200A over the cable (which'd require 250kcmil Al, since the 83% reduction in 310.15(B)(7) doesn't apply to your situation), but need a 4-wire cable as your shed is getting powered by a feeder from your service disconnect at the pole, I'd …

The National Electric Code (NEC) requires “Distance from the subpanel due to voltage drop (NEC 310-16 Code),” and by using the factor you will find that a 100-amp service requires a maximum of #3 AWG ground wire. A wire with a diameter of 3 AWG can handle 100 amps. The NEC code specifies the distance between a sub-panel and the wiring.I am running 100 amp line from my service panel to my subpanel through 100' of underground PVC. I have to use copper per local code. I am going to use #3 Cu for my two hot wires. 1) What AWG size does my neutral wire have to be? I found this: Per NEC Sec. 220-22.

If this is a new installation, you should have an EGC (ground wire) running back to the main panel, in addition to the ground rod (4 wires total), with the neutral and ground remaining separate back to the main panel. If, however, you have 3-wire service to the garage, neutral and ground *must* be bonded in the subpanel.If you consult the KCMIL list above, you can see that the 350 KCMIL wire is perfect for 200 amp service 100 feet away. That’s because it has a 310A ampacity.

The wire size for the power conductors was determined by Table 310.16 in the National Electrical Code (NFPA 70) under the 75-degree column. I used the 75-degree column because the wire insulation was rated for at least 75 degrees Celsius, and so were the terminals on ...Equipment Grounding Conductor (EGC): Table 250.122 The EGC of a branch circuit bonds the noncurrent-carrying metal parts of a connected load back to the grounded metal parts of the electrical distribution panel where the circuit originates. This EGC can be a wire-type or it can be in another form such as an approved metal conduit.

The thought behind the junction box is to give extra room for bringing the wire/cable into the 2x4 wall before entering the service panel. The conduit will go around my shop to a 125A sub panel located in an attached carport that will support a welder, car lift, large compressor, plasma cutter, and lights/outlets.You need to know the size of the breaker for the sub panel, and the size/gauge of the feeder wires.

Running 2 - 100 amp sub-panels you should run #3 THHN wire to each panel with a 100 amp breaker to feed each one. The NEC recommends 3% voltage drop for either the feeder or the branch circuit and 5% total for both. This is only a recommendation and never appears in the text of the code so it not enforceable. However, it is a very good idea.

But 75 would be enough so it’s best to jump up to 90 or 100. 75a = 2 awg wire with 2.56% voltage drop this would also handle 90 amps to go up to 100 amp 1 awg wire would be needed. With older panels finding anything larger than is doubtful. With max loads listed #2 and a 90 amp breaker would give additional room. – Ed Beal.
