3 phase service

[jph320]

I am going to put in a 200amp 3 phase service in a garage. Any tip on how to get my wire form A to B? I need to go along the roof line about 15 feet, enter the building through cinder block and down the wall 10 feet to the meter socket. I heard I could use SER cable from the weather head across the wall outside and enter the building then use 2in emt to protect it down to the meter. Is this true?

not without disconnection means. Meter on the inside?

 

[jph320]

yes meter on inside then nipple over to the panel.

I believe code states 4 feet of service entrance wire on the inside before a disconnect is needed. Better check that first before anything else. I live in Pittsburgh, and there shall be no metering on the interior of any structure.

i was gonna put th meter outside but it is there driveway for moving cars in and out so I thought inside would be the safest. I was thinking about using 4 conductor SER cable too since they don't make that in SEU. Is that legal? I can't find that anyware

Not THE code. "Nearest point of entrance" is as specific as it gets.

Thank you, sir.

Your POCO may not allow the meter on the inside of the building. Best to find out first.

Glad that someone pointed out that the "Mythical 4 Foot (or 5 foot as I was taught) Rule" doesn't really exist. I once put a panel in the next stud space over from the penetration and when questioned by the inspector, I told him it was well within the 5' rule. He told me to go to my code book and look that up while he inspected the rest of the house. I came back with my tail between my legs. He said "It isn't in there, is it?" Luckily, he was in a good mood and let me get by that time!:grin:

check out section article 511 in the 2008 nec code book, if this is a commercial
garage you may be required to run it in conduit .

Thank you for straightening me out. Would not have thought that next stud over would be a problem. Will keep that in mind in the future.
