A sub-panel connects to your home’s electrical wiring through a double-pole breaker on the main panel. The wire gauge you use to connect the two depends on the distance between them and the size of the breaker. Generally, it would be best if you had a 10-gauge wire to connect a 30 amp sub panel, 8-gauge to connect a 40 amp one, and 6-gauge ...

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.

The size of the wire required for a 100 amp sub panel depends on the length of the wire run and the type of wire you are using. Generally, a 100 amp sub panel will require 6-gauge wire, though larger gauge wire can be used depending on the length of the run. If the wire run is over 100 feet in length, then 4-gauge wire may be necessary.new jersey. Aug 16, 2013. #1.

Correction:. I meant to say #8 for the ground. Thanks all, I will go with #3 for neutral and #8 for my ground. In most cases the grounding electrode conductors (ground wires to ground rods etc.) are #6 copper to direct buried or driven rods and #4 copper to water pipe or concrete encased rods.

The ground wire size for 70 amp is 4AWG. You can use the same gauge for the hot, neutral, and ground wires. The ground wire is a defensive component that directs the current to the earth when a malfunction occurs. You can also use a larger ground wire than all the other wires because it has less resistance. This is a good goal to shoot for when sizing the conductors for an underground cable. The following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size (AWG) and circuit voltage. As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 ...Panel & Breaker Accessories. Raceway Support & Hanging, Box Positioning Products.
