Concentric Neutral & Spliter Box

1026 Views 4 Replies 3 Participants Last post by  brric
We're on a farm and we are going to change all our secondary from overhead to underground. What the guy from the power company suggested is to move the transformer and the meter to the road. They're replacing the main line, so they'll do this at no cost to me. Then the secondary will run to a splitter box on the side of my shop, and split off to the shop, the house, and a pumphouse in the yard.

Two questions. The first is, what is the best way to isolate the box, which is metal, from the metal siding? I'm thinking just wood. The second question. The secondary is USEB, which has a concentric neautral. So when that is twisted and comes into the box, is it insulated somehow, routed so it doesn't touch the box or what? Again this is just a splitter box and not a panel.

Should have mentioned I'm in Canada

Thank you for the reply Allan. I know about grounding the box. The cable only has 2 hots ( insulated) and the concentric neutral which is insulated within the main cable but has to be twisted together thus stripping the insulation.( you probably know that already). All service panels, house shop etc. have their own grounding rods in place. Yes the lugs in the box are insulated from the metal box itself. My concern is that piece of bare neutral from the point is enters the box, to where it connects to the lug. It's only about 6 to 8 inches but it bothers me that it's bare.

Guy from the power company said #2 should be adequate but I went 1/0. Also, anything on the pole is taken care of by the power company so any switches etc. that are needed will be installed by them.
