Like the famous line says, long-time lurker, first time poster (waves to the room).
My wife and I bought our dream house this past October and the pool had already been closed. The pool details are in my sig. We knew the pool needed some major TLC so we budgets for some fun upgrades. Starting 2 weeks ago, we replaced the liner, installed a heater, and I'm waiting on a ColorSplash 3g to be installed. I've also purchased an Autelis, EasyTouch 4 and an IC40 as I would like to automate the pump (about to upgrade to an Intelliflo variable-speed), lights, and heater. I've been using the TFPC method and have a TF-100 test kit. The chemistry is spot-on but I now want to get my SWG up and running.
I received the EasyTouch a few days ago so I decided it was time to take a look at the subpanel. I found that there is no GFCI in the main breaker, so I naturally assumed there would be GFCI breakers at the pool. Nope. Not even for the pool light. There is #6 wire in the existing sub panel, and only three of them. 2 hots and a bonded ground is what I'm guessing. Oh, and the existing copper ground wire, which is connected to the pump, went to a metal stake buried about 16" into the ground. I dropped in an 8' copper ground rod using a home-made water drill into a salted hole, so at least that part is done, but here's my issue.
The pool is about 80' from the house, and has a pool house. It's 60 amps at the main breaker feeding the sub panel, and is mixed 220/110. Can I install this new panel and have working GFCI 220 (pump / heater) and 110 (light, automation, everything else) breakers? How would I need to go about wiring the neutral and ground? I really don't want to have to run 4-wire to this if I can avoid it, since it should be grand-fathered in due to the age of install.
Thanks for any help you can give!
