Replacing line cord on Pentair pool light

[Bill1974]

Does anyone have information of replacing the light cord that is an a large Pentair line voltage light? I would like to not have to put a whole new light if it's possible to just replace the line. If I recall there connection inside the light are just crimped on lugs. I would imagine where the cord passes through and seals on the housing should be replaced when the cord is replaced. Any one have a lead on what grade of cord is used and where a replacement gasket can be found.

The cord and the seal is not designed to be replaceable.

Pulling the cord is the major effort in replacing the light. Why not just replace it with a new light fixture?

I am moving the junction box where the light is connected so I will need a light with a longer cord. The cost of a cord is cheap compared to a new fixture. I think cord is maybe 10 feet right now and I will need to be 30 feet. Not that far to pull and there is only 2 90's deal with too.

I am pretty sure I am going to end up with a new fixture. I was just checking to see if it was a possible to save a few bucks. I don't recall, but I think the connections might be potted in and not accessible. I am also aware this is the safest option. I think just the ground might be on a lug that is accessible.

No, don't attempt it, you can, literally, put electricity into the water by trying to splice a length of cord to the existing light cord. They come as an assembly only. Do not forget the bond wire that will be inside the light niche. You will have to install a new one to reach the j-box as well. They, too, have to be continuous from the bonding lug in the niche to the bonding lug in the j-box. The bond wire is, or should be, in potting compound in the back inside of the niche. You will have to dive into the pool or drain the water to replace that very important wire.

You can't splice the light cord.

I would not try to disconnect the bonding jumper from the inside of the niche.

It will probably break off and you will not be able to reconnect it.

If you can get approval from the local inspector, I would recommend that you splice the bonding jumper using a high quality solder.

The bonding jumper is already exposed to the water anyway.

Have an electrician splice with solder and only if you get approval from the local inspector.

The code says that the wire has to be used but it does not say that it cannot be spliced.

Ideally, you would use a continuous piece, but that might not be the best choice.

If the inside lug breaks off, you are not going to be able to reconnect the wire.

If the pool is more than about 2 years old, the bond lug will probably not be good enough to be able to disconnect and reconnect the bonding jumper.

A spliced bonding jumper is better than no bonding jumper.

Rust from pool light ground wire

I had new Hayward Pool Light (non LED) installed last year. Shortly after, I noticed a streak of rust stains appearing above the light. The streak is easily cleaned with Vitamin C powder in a sock and being doing that every two - three weeks. I finally removed the light from the Niche to see...

If you can't get approval to splice from the local inspector, you can try to disconnect the bonding jumper to replace it and maybe it will work.

If the lug breaks off, you will probably have to replace the conduit with metal conduit or go to low voltage lighting.
