Relocation of pool light junction box, bonding cable question

[Trdavis]

Hi guys
i’m in the process of moving the junction box for my pool light. When I opened the box, I found a bonding wire from the light along with the light cable. both running through the gray pvc conduit From the light. another conduit with 3 wires coming from the transformer on the side of the house. I’m replacing the light and extending the cables to the new cable junction box location. My question is how to extend the bonding wire. Can this wire be spliced in the inside the conduit? Or should I run a new wire from the light housing. The wire appears to be attached to the light housing but I don’t see a way to remove it and replace it. Looking for options. I have the pool drained so I think this is a perfect time to do this. I will attach some pictures of the light housing and the connection to the Bonding wire.

You're not likely going to be able to remove the bond from the bond lug, the encapsulation seems to have failed and it is very corroded.

That’s what I was afraid of. do you think splicing is an option, if so would it be best to splice close to the lug and use something to encapsulate everything

If you have a low voltage light, you don't need the bonding jumper/supplemental ground.

Edit: The code might require the bonding jumper if it does not specify an exception for low voltage.

Therefore, I would keep the bonding jumper unless you can verify with your local inspector that it is not required.

Yes, low voltage. Well that’s good news. The pool is 35 years old. maybe the original light was 110v. What is in there now is low voltage, regular light, and we’re replacing it with an LED light.

Listed low-voltage luminaires not requiring grounding do not require a ground.

In my opinion, this means that the bonding jumper/supplemental ground is not required because its purpose is grounding, not bonding.

The bonding lug is provided at the back/outside of the niche and the niche should be bonded from the back/external lug.

However, this might not be specified in your local code.

The code might require the bonding jumper if it does not specify any exception for low voltage.

Therefore, I would keep the bonding jumper unless you can verify with your local inspector that it is not required.

Thank you everyone, I’m going to keep the bonding wire just in case. Splice right at the binding post and encapsulate it all. That way the wire is there incase ever needed. Don’t plan on seeing the inside of this light housing again… lol
Thank you everyone for all the info.!!
