Pool junction box to pool lights

We demod our pool concrete deck to put on some pavers. Were going to get new pool led lights and the pool company is going to install that.

Since the current junction box going to the subpanel is old copper conduit, we are going to replace it with pvc. Pool company charge too much to replace the conduit.



What type of wire and size is typically used from subpanel to the junction box? I read the led light manual, all it says is minimum 12g wire. Will THHN work or a an outdoor wire? Old lights was on a 15amp breaker. New ligjts, dont know.

Also forgot to ask, can i run the wire for the lights and wires for some outlets in the same conduit? Maybe 1/2 or 3/4?

Dont know if thats allowed but that junction box has 3 holes so i thought one could be the source, one could go to the to lights and one could go to a few outlets in the yard?

that way i dont run the lights and the outlets in the same circuit.

Hi, as long as the voltage rating on the insulation is the same, no problem , you will need THWN or equal for the wiring underground.

I believe the conduit is required to be metallic.
Article 680 requires corrosion resistant metal conduit.

We demo’d our pool concrete deck to put on some pavers.
This concerns me to say the least.

​​​​​​​Pool company charge too much to replace the conduit.
This may be money very well spent in this particular case!

Since the pool deck was demo'd my major concern is since this is a built-in pool whether any of the bonding system was disturbed during the process? The proper bonding of a swimming pool is paramount for the safety of all that may be around and in the pool at any time.

The proper bonding of a swimming pool is not to be "guess work" or "I'll try and do it myself" kind of work.
You get only one chance to get it correct. One mistake can cause the pool to be a death trap to anyone or anything that is living.

Knowledge of the proper bonding of a swimming pool is not something that all electricians have. It takes special expertise and training. This is usually not a DIY project. When the deck was demo'd and pavers placed did you have anyone inspect the bonding system to be sure it was not disturbed? Do you know if you can use PVC instead of copper as a replacement as PCBoss stated?

I would highly suggest that you spend a little bit of money to have peace of mind in this case.

Again, there are no second chances with this.

Remember, electricity and water do not play well together.

I turned down every swimming pool job where I was asked to give an estimate for work. I did not have the specialized training so it was not worth the money I would make on the job to put person's lives at risk.

Read this and some other articles about proper bonding of in ground swimming pools.
