THHN/THWN THHN.The correct 40 amp wire size needed to operate with a 40-amp breaker safely is an 8-gauge wire. It is possible to install a 40-amp circuit breaker on a larger gauge wire, such as a 6-AWG wire, but installing it on a smaller gauge wire will violate the code. Using a smaller wire gauge for a 40-amp breaker violates the code and presents a safety ...YES you can use #4 Al as your ground. Your 1AWG Al is good for a 100 AMP feeder (actually 110). From NEC 250.122 this requires an #8 CU or #6 Al ground wire as a minimum (or 6CU and 4 Al if you are really running a 110Amp Feeder). As a reminder, your feeder will be 4 wires, the two hots and the neutral will be #1AL (unless you've de-rated the ...

A 100 A sub-panel requires a two-pole 100 A breaker - if you want 100 A. You can use #4 AWG 75 deg C or 90 Deg C copper wire in conduit for a 100 A breaker provided the breaker is labeled for use with 75 deg C wire. A #8 copper ground is adequate for a 100 A feeder If running NM cable or SE cable, you would need #2 copper, I believe.

In this case, instead of using a 2/0 copper wire, you should use 300 kcmil copper with only a 2.78% voltage drop. This suggested size wire for a 200 amp panel will work for both single-phase and three-phase installations. On the other hand, if you are tight on budget, you can use 500 kcmil aluminum.Wiring the Sub Panel. When mounting the sub panel, make sure it’s about 1 foot away from the main service panel and measure how far each wire will need to travel. Plan the routes for the ground, neutral and black and red hot wires. Strip enough wire sheathing to attach the wire; then remove a knockout slug and clamp the cable in place.
