I am going to be putting in an inground pool 16X32 and am looking at the electrical requirements. The plan is to put in a subpanel at the pool from my 200 amp main service in the house. The run will be approx 130 ft Some questions: 1. Can I put put in one 40 amp GFCI breaker in the main panel (for my feed to the sub panel) that will protect everything in the sub panel (pump, pool light, recept, and building lights) 2. Was planning on using 8-3 NMWU to the sub panel. 3. Can I use a 60amp sub panel for this.....pump wired at 220 using 2pole 15 amp breakers and one 15 amp for the pool light and one 15 amp for the recepts and lights? Thanks for your help Jeff

running into a money issue trying to retrofit the working parts of a hot tub to a second non leaking tub. when i got the parts, the seller neglected to tell me that the original tub came with a sub panel, now im forced to create one. i thought this would be a great opportunity to put electricity in my garage, and a close location for the gfci breakers on the tub circuits. the manual says the sub panel needs a 50 amp 240 service, the sub panel includes 2 di pole gfci breakers, a 20 amp and a 30 amp. after some research, the prices are just a little too much for this once thought, simple project. i acquired a square d (home line) box with a 100 amp service from the family farm. please correct my logic, but i thought that i could replace the 100 amp main with a di pole 50 amp gfci breaker then place a 20 and 30 amp di poles in the box and run the wires as directed in the manual. my thoughts are that the whole box then would be covered by the gfci in the main breaker. since the 30 amp breaker is for the heater, which is non covertible to 120. and the 20 amp is for the pump motor whoever is convertible. now i tried this, i fried the gfci in one breaker so far. besides that all wiring is working and im getting 120 off of both hot leads. i believe that im confused how the gfci works and how to hook it up. the first time i wired up the 50 amp gfci main i had the two hot loads (red and black) coming into the box directly connected to the breaker. im a little lost with the load neutral and pigtail. i connected the incoming neutral to the main neutral bar slot. then connected the pigtail to the neutral bar. i also considered how the gfci would work if there wasn't a fourth wire (neutral) connected, so i connected a wire to it and connected that to the neutral bar. when i turned on the power the lights came on and when i tested the gfci it didn't trip. i deiced that wasn't right and it didn't seam logical to wire the gfci that way. when i fried the gfci i wired the incoming neutral directly to the breaker and the pigtail to the neutral bar main slot. when i turned on the power everything worked until i tried testing the gfci. some not so good sounds came from the breaker and i turned it off. this didn't trip the 50 amp breaker in the main panel. my next thought is that i need a different breaker. that maybe you cant use a gfci that way. maybe the electricity only flows through the gfci one way and hooking it up as the main is backwards for that breaker. sorry about the rambling, but i cant sleep, not because of this though.
