4/0 Al for a 200 amp service? Can you give me a code reference for this one. I know of the 5% rule but 4/O doesn't fall within 5%. I am sure your correct as you have probably done 10 times more residential services than I. I just want to know how we are allowed to use 4/O on a 200 amp service.
I guess this is what happens after 6 years when you leave construction and go work in the plants. You forget things! It is all coming back to me though!
Table 4 of your code book. See the double star ** beside the 185? See the footnote. You can also use 2 ot copper!
