Question: what is the difference between #2 wire and 2/0?
Answer: Again I ask, Is this the correct wire size for 200 amp breaker and/or what is the difference between #2 and 2/0?? Thanks. 2/0 (two naught) pronounced “two not” is a larger wire and will carry the 200 amps by your codes. ... 2/0 (two naught) pronounced “two not” is a larger wire and will carry the 200 amps by your codes.
