State is Florida. I am wiring a continuous run non-submersible irrigation well pump. I am using a 30A breaker with #10 THHN in Sch 40 PVC conduit buried 18". I could have gone direct bury but I feel safer in conduit in case either me or the next homeowner dig.
I have a pump start relay that is controlled by a rain bird sprinkler controller. The controller is all the way in the garage. Since the sprinkler controller is far away I want to wire in a simple switch in parallel so I can flip the pump on if needed (I have a hose on it, need to test it, or something). Since I'm going through all this trouble I might as well give myself an outlet.
My questions are:
- Are parallel circuits allowed per code @ 220V?
- Am I correct in bonding the neutural and ground since this is an outside panel. I assume I still need to run a neutural for my GFCI.
- Is there a better, cleaner way to do this? Perhaps a small 24V transformer on a switch?
- How many splices am I allowed? I would assume splices have to limit something. Can I splice 4 wires into a splice w\ wire caps?
- Is it ok to use stranded THHN? That's all home depot had.
Here is my wiring diagram.
