Maybe this will help. It's not that difficult of a situation, so here's the details of the installation. It's an existing agricultural set up with an existing residential dwelling. The utility comes in to a xfmr pole and from there they run triplex to a meter pole. At the meter pole, the utility goes through a CT (last utility point) and into the pole top disconnect switch. It doesn't matter if it's double throw or not. It's a disconnect and it's owned by the member. On the load side of the pole top disconnect, the existing house and all shed are fed with overhead conductors. Now, they are eliminating the existing dwelling and bringing in a manufactured home. I am going from the load side of the existing pole top disconnect, down the pole, underground to the breaker panel in the new home. My question was, is it necessary to put a grade level disconnect at the bottom of the pole before going underground to the house, or is the pole top disconnect sufficient?
I was thinking that you didn't need a grade level disconnect at the bottom of the pole, beneath the pole top disconnect as long as it wasn't feeding an agricultural building, so in this case, there is a disconnect at the top of the pole and it's feeding a dwelling and a grade level wouldn't be necessary.
