Hello, I'd like to know what size wire I have to use coming from my breaker box to the meter. I have a 70' trailer in Vermont. Basically the electric company said put that in with the meter pedestal and they'll do the rest. I looked at the wire coming in the box, it says E 18679 (U/L) with AWG 10 ground 600 volts. The trailer was moved from up north and that is what was in it before it was cut. My neighbor is supposed to be doing most of it but I need to buy the wire. (He's currently away at his daughters wedding) What wire exactly would I buy. The pole is on my land and is about 15' from my house? Any feedback would be greatly appreciated. Have a great day.

The key information that we need is the amperage of the master breaker in the electrical box for this trailer. Please look in the box for that, and report it here.

OK, then you need a minimum of #4 copper (or #2 aluminum). For this short a run, those will work fine.

But 100A is a pretty small service nowadays. If there's any chance you might someday upgrade that, or add on to the trailer, or replace the trailer with a bigger one, you might consider installing a larger service line now. It won't cost that much more to do that now, and will be cheaper than doing it later.

#1/0 copper will allow 150A service.

#2/0 copper will allow 200A service.

Does it need to be a solid line or can it be spliced into? For example: I moved my tralier where one was setting previously. There is already wire ran up under the tralier but it's about 4 foot to short to reach the trailer where it is supposed be wired in. Do I need to replace all 50 feet of it? Or can I just add to it?
