service rating

[jnsh2]

I understand that 2/0 thw copper is no longer allowed for 200 amp. Is it 3/0 under new code? Also, 150 amp now requires 1/0 copper?

Absolutely correct and it never has been unless it is a dwelling unit in Table 310.15(B)(6).

I never thought those were allowed, anyway...it has always been the same to me since I owned my first NEC code book (1996). Unless I've missed something. Heck, I've only been in the trade for 5 years...
