I have a 10+ year old in-ground pool that was installed by a previous owner. The wires feeding from the outdoor pump house were ran in seal-tight and buried. All the other equipment (including the wiring from the light niche to the pool j-box and from the pool j-box to the light switch) are all in pvc conduit. It is just the run from the outdoor sub-panel to the light switch that was buried in seal-tight. Well, the seal tight has degraded and broken where it comes out of the ground near the outdoor subpanel and the metal has nicked the coating of the neutral and ground. I was originally just going to bury a watertight j-box and make a joint there, but the switch is located at my deck and it would be very easy to feed from my main house panel. Is there any reason (code or other) that the power has to be fed from the pool sub-panel and not from my main home panel?
