Conductor size for service drop

[102 Inspector]

Given a 200 amp overhead service drop, I read Table 310.16 (2008 Ed.) that 250 alum or 3/0 copper will be required. Using the 75 degree column I think this is the correct chart to use. This is for a fair booth that has commercial cooking equipment so I will not use the residential reduction chart. Just want to make sure there are no other exception I might be missing. They have not provided any load calculations yet.

It is somewhat rare that the rules in the NEC would apply to a service drop.

Agree, usually the utility supplies the drop which is their rules -- must have a lenghty riser

I have seen where the utility will not install a service run and it falls the the electrician and the NEC. You may want to look at 310.20 if you are running it on a messenger the ampacity of the conductors is higher.

It is amazing how the story changes when you finally get all the facts. The electrician and I were discussing 2 separate components and that is where we disagreed. Once we got our facts straight, we both agreed on wire size and installation method. Kinda like talking to the wife or kids.
