We just bought a house that needed some upgrades and one of the first ones up was the electrical panel. Hired an electrical company to come out and upgrade it to a 200amp box. Work went fine and everything passed inspection but they didn't wire in a switch to control the pool light Previous owner had cut the wires to the light switch so all that is left is the junction box (wires from light and leading out to missing switch are connected) by the pool and a pipe that contains the cut wires.
When I asked about adding the switch for the pool light I was told it would be a couple hundred dollars since the work order only listed providing GFCI protection for pool light. So my question is can I add a second switch by using the switch that already exists for my pool pump? They also installed an exterior outlet so I'm not sure if I can tap into that instead.
