I bought a home with an existing pool 2 summers ago. I noticed that out in the pump house, a piece of sealtight has broken and cut partially through the ground wire of the pool light circuit. There is sealtight running from the subpanel to about 4" underground. At that point, there is a male NPT connector beginning the run of 1/2" plastic conduit. The broken sealtight (and wire) is in the sealtight between the palstic conduit and the subpanel.
In lieu of pulling all new wire for the entire circuit, I had planned on installing a watertight PVC 4x4 junction box at the end of the conduit, creating a joint for each of the wires, and running sealtight from the box up to the subpanel.
Can anyone tell me if this meets the NEC for pools? I do not have a copy. Thank you.
