Howdy, We are in process of having pool installed, builder installs pool and concrete but since everybody's electrical needs are different he doesnt price that with job. Instead he has electrican he recommends and then electrical is between you and him. Well electrican and I butted heads right away over several things, such as I wanted more service than neccesary to run pool so we would have enough to run pavillion when we build it and I wanted to run service from house to pool in conduit instead of just putting uf feeder to it, uf is fine but we still have lots of stuff going on in yard since house is new and we still landscaping and such and its lot easier to find conduit without cutting wire than just buried wire. I decided to let electrican that wired our house help me but a few things are puzzling us. Now that I hit every bump in the road Ill ask my question. The pool guy ran 12-2 uf for the lights, 2 lights, 300 watt 12 volt, one is about 40 ft from equipment pad and subpanel and the other about 80 ft. I intend to put px300 transformers to run lights, according to the install guide they should have had bigger wire if I plan on placing them by the subpanel rather than beside the pool where the light wires come out of ground. My orginal plans was to mount the transformers beside the subpanel and just put watertight jboxes where the pool lights and uf feeding them meet. Should I pull bigger wires for the lights, mount the transformers next to lights, or take a chance that 12-2 will run lights without issues. Dont even know if anyone can understand question as much as I rambled.
