[Pool Light Gfci - Electric Question]

 

The pool light should work off 12 - 14 volts AC. No way will it or should it be working off 110 or 220 volts! There should be a heavy duty transformer somewhere - in your poolhouse or similar. I believe Canadian codes require a GFCI in the circuit breaker box feeding the transformer. Depending how yours is wired, the pool light switch may be switching the 110V to the transformer, or possibly switching the 12 to 14 volts between the transformer and the underwater light.

 

You know that they sell 500 watt 120 volt pool lights right? Because they do go look them up. We have a 120 volt led pool light that has the transformer right in the Light so no worries. If you pool is as old as you say it is I I will most likely have a 120 volt light in the pool that does not change color.

Yes that might be a problem you should put the cover back on the box and if it is missing you should get a new cover. You should never have 230 volts of power exposed the the elements. Also yes it is just as simple as that and if you get one of those books that they have at Home Depot about electrical you could probably do it yourself.

[Pool Filter Under Sizing]

I am going to be putting in a pool this sumer that is going to be 40' by 20' and is going to be 3' 6" deep in the shallow end and 10' deep in the deep end. I am going to have an automatic pool cover for the pool. I am also going to have an ozone sterilizer to take the place of chlorine (tell me your thought on this ozone thing). My question is can I have a pool filter rated for 175 sq. ft. if I have a cyclonic filter right after the pump from Water Co. (Multicyclone 16)? Or do I need to get a pool filter rated for my pool even though I have a pre filter trapping a lot of the contaminents before it comes in contact with the cartridge?
