American Wire Gauge. Measure the thickness of the cable.
It stands for American Wire Gauge and a designation like 10 AWG indicates the size. There are a number of other specifications which derive from the cross sectional area of the wire as designated by the gauge. One confusing aspect is as the number of the gauge gets smaller the current carrying capacity increases.
6 AWG wire
WIRE
AWG 10.
Size 12 in the American Wire Guage (AWG). It's a wire of about 1/10 inch diameter.
Using the AWG for wire sizes only goes up to 4/0. After that the increases use MCM to size the wire. So your 262 MCM wire size will be same in AWG. There is no 262 MCM in the North American market place. It goes in 50 MCM increments starting at 250 MCM , 300 MCM, 350 MCM, 400 MCM right up to 2000 MCM cable.
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
AWG # 6 copper or AWG # 4 aluminum
AWG # 10 wire.
The nearest wire size is #6 AWG which is .162023.
Use only AWG # 10 copper.
