What size neutral wire do I need for a 100 amp service?
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.
What wire do I use for a 100 amp sub panel?
#4 copper wires
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)
What size wire do I need for 100 amp service 100 feet away?
If you check the wire size chart (you have the link in the introduction), the #0 AWG wire (also known as 1/0 AWG wire) has 150 ampacity. That means that #0 AWG wire is the perfect size wire for 100 amp service 100 feet away.
What size ground wire do I need for 100 amp sub panel?
You are correct that for a 100A feeder, the associated ground wire needs to be an 8AWG copper or 6AWG aluminum wire.

What size wire do I need for a 100 amp underground 300 ft run?
for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit, …
What size wire do I need for a 100 amp underground 150 ft run?
