copper 1/0 thw

Does anybody know if you can use copper 1/0 thw for the service entrance from the disconnect to the main panel for a 200 amp service? It is rated for 600 volts and wrapped with a oil resistant insulation. My location is Columbus, GA.

no, 1/0 is only good for 175A, needs a minimum 2/0 copper or 4/0 Aluminum.

This is assuming single phase residence service.

Nope.

Residential you'll need 2/0cu.
Non-residential you'll need 3/0cu.

Thaanks guys, I had a neighbor give me about 50 feet of it. Guess I will strip it and scrap it.

If the lugs can handle it, namely listed for 2 conductors, 1/0 is the minimum size allowed to paralell conductors but it does have to meet the criteria spelled out in the NEC.
