Junction box for pool light

[jholling]

Hi,
I am running the electric for my in the ground pool. I will have a light in the pool. My question is do I have to run a seperate conduit line to a junction box specifically for the light or is it ok to run the conduit back to my main juction/timer box? Givin that the main junction/timer box will be 24 inches above the max water line? If I need a Deck Box? Can that be mounted on the same 4x4 post?

Thanks,

Jed

Jed thanks for posting on the forum so others can learn. I already answered this for you but it should be help to others reading this forum. Again thanks

Depends on if this light is a low voltage light or 120 volt light.

I am taking it you have a 120 volt light.

Then it depends on if you have a wet niche underwater light or a dry niche underwater light.

Most are wet niche underwater lights 120 volt rated.

If this is what you have you must install an underwater light junction box at least 4' away and at least 8" above the water line. Remember your light comes with a cord. That cord must reach your underwater light junction box located at least 4' away and at least 8" above the water line. Be aware an underwater light junction box must be listed for use with an underwater light. This junction box may be metal or plastic but will contain a large green screw designed to accept an 8 awg copper bonding grid wire. The coduit you install between the underwater light and the underwater light junction box must be either brass or PVC. If PVC then you must install an 8 awg solid copper bonding grid wire in that conduit with that rubber cord connecting to a lug inside the wet niche light and the other end to that large green screw in that underwater light junction box. Longest cord I heard of for these lights are about 25 feet. This is often a problem to pull that rubber cord through a conduit. Keep that in mind.

The underwater light must be served by a dedicated branch circuit directly from teh main panel serving the house or pool shed designed for a pool. This circuit must be inside a conduit with a green insulated equipment grounding wire 12 awg minimum size. The only devices allowed in that circiut serving an underwater light is a switch, GFI protective device and underwater junction box.

Good Luck

Hi!

When I use low voltage luminaires do I have to use the junction box? What about the transformer, If I have a "house of machines" where panel, pumps, and other equipment are located, could I locate the the 120/12V transformer there? How then I supply 10 luminaires for example?

Could you explain me briefly how can I perform a low voltage luminaire circuit for the pool?

Thanks in advance.

Are these lights underwater lights or perimeter lights on the ground? If on the ground, how far away from the water's edge do you want to put them and how high? Pool lighting is a pain in the butt, and you don't get much relief by going low voltage.

I agree>>>with the pain in the butt part.

Ifed,

next time try to start a new tread (tread is almost 4 years old) . If you want you can start one, and we will take care of the rest.

Ohm1, Im going to take account your advice, but for this time Im going to continue in this thread.

SueMark, my luminaires are going to be underwater, wet niche, low voltage (12V).

We are designing an irregular shape pool and I will have too much lights. I will also have three structures in different places in my pool where I will put pumps, panelboards and other electrical equipment.

My question is about the low voltage circuit for this lights. I will have to use a 120/12V transformer (I guess!) and I dont know where must be located. (in the structures or in another place closer to lights).

Then, how much lights can I connect to this transformer circuit? Could you explain me a little bit how this circuit could be performed? Do I use junction boxes?


Thanks a lot!
