Hi,
What article allows 2/0 copper for a 200A service? This is a residential application. It is 310.15(B)(6) isnt it?

IS there a table for commercial service entrance ampacity?

Thanks for any replies.

-regards

Greg

No special table for other than dwelling units.

For a commercial service you will use 310.16 and the 75 C column.

Hi Greg: you are correct,Table 310.16(B)(6) is allowed to size the service conductors for a dwelling.
