I'm wiring an above ground, outdoor gasoline storage tank with a dispensing pump on it. The tank is surrounded by a chain link fence. I was going to run 1/2" IMC about 20' from the J box to the fence and up a mast to a weatherhead for an overhead feed.
Do I need any sealoffs in this run? Where would they be located?
The J box in the pump?? If so, yes would be my answer. Conduit going underground? if so last fitting before it enters the ground at pump and first fitting after it exits the ground at fence
