Pool lights wiring at breaker box

Good evening everybody.

I recently purchased a house with an in-ground pool in the backyard. I knew at time of closing that the pool lights did not work, but didn't know if they were just burnt out or if they actually never worked. I have replaced the lights successfully using the equivalent light in LED form, but I cannot for the life of me figure out how to turn them on. In my breaker box, there are 3 breakers. One controls the pump, one controls an electrical outlet on the side of the box, and one controls something else that I can't quite identify, but it does not change anything whether the breaker is on or off, at least from a lighting perspective.

In following the wires from the lighting system into the box, of the five wires, Green, White, Red, Blue, Orange, the orange and blue wires are going into separate relays toward the top of the box. The green wire is going into ground, the white wire is wired to the electrical outlet on the side of the box, and the red wire is wired up top to the actual timer/control unit for the pool pump. None of them are connected to breakers, but I'm assuming that the relays have some significance. The relays output into black and white wires which connect into a plastic piece that looks like it should be plugged in somewhere, but it isn't.

Clearly this is a bigger task than I had imagined. I assume that they must've worked at some point, and if not, they were correctly wired when the house and pool were constructed.

I can provide any photos necessary, the ones I have now are evidently not good enough to explain anything that's going on. The box is a total mess of wires, and I know an electrician will have to come and solidify the solution, but at least on a temporary basis I'd like to see if the lights even work.

Any advice would be super helpful, thank you very much!
 
Ryan,

We need to see some pics...

Generally, you don't turn pool lights on and off with the breaker. You should have switch somewhere. Often at a junction box near the pool or switch inside the house or porch.

Thanks,

Jim R.
 
Ryan,

Fellow pool novice here. I faced the same situation last year with our new-to-us pool. Our problem was a defective GFCI outlet which was wired into the pool lighting circuit. Is the electrical outlet you referred to a GFCI? Perhaps it needs to be reset, or, as in our case, replaced.

Couldn't hurt to check. Good luck!
 
Do you have a junction box near your pooi?

It is a GFCI outlet, so theoretically that should be the switch controller for the lights?

No, the outlet is just an outlet. There should be a switch or relay somewhere that turns the lights on and off. Is the outlet getting power?

When you replaced with LEDs, did you make sure to use 120 volt bulbs and not 12 volt?

Yes, the outlet does provide power, and yes they were replaced with 120V which is the voltage required by the housing.

So, the GFC outlet could be causing the whole issue even though it isn't connected to the wiring for the pool?

If the white wire from the lights are going to the load side of the gfci outlet as stated then it Is very likely that the light is wired through the outlet. Does a black wire, also from the load side of the gfci outlet, go up to the relay that the wires from the light lands on?

Hello everyone! As promised, attached is a photo of the wiring diagram. It's all messy, but maybe somebody can help identify what is going wrong here. I've highlighted the wires as they leave the light box and enter the breaker box.

It appears something is wired funky as white is clearly going to the gfci but hot does not appear to be. A defective or tripped gfci will disconnect both the neutral and the hot and since your lights are connected to the neutral, I would start there. Does the gfci outlet work? Did you open the light junction box and get a photo?

Yes, GFCI outlet does charge my phone. Here's a photo of the wiring in the junction box.
