I am presently at the design stage but we plan on running 2" PVC from inside the church to the outside and come up from 18 inch depth to a cb panel.A distance of 165 feet. I plan on useing #2 thhn What is the minium height I can get away with for the panel height.I want to keep it as low as possible. As for the time being we plan to coneal the panel inside a rubbermaid shed. We plan on useing unistrut to mount the panel on.till next year when a outside Baptistry will be built. We plan on going further on with inch and a half to a sub panel 222 feet away for 4 outlets and a sign for the church. The outlets are for Christmas lighting small displays only ( I hope)
