2 part question. I'm looking to do this the 100% correct and safe way, but can't find an answer.
Part 1. I'm looking to feed my well pump with a generator in power outages. I purchased the Reliance Controls CSR302 manual transfer switch. This unit takes my generator's L14-30 connection; I have the extension cord just for this to plug into the transfer switch. This issue is the wiring, see picture. My well pump has a 220v 3-wire; two hot and ground.
Per the instructions for the CSR302:
- the 2 red wires connect to the 2 hot feeds coming from the breaker panel
- the 2 black wires connect to the two hot feeds going to the well pump
- the green wire would connect to both grounds (from the panel and to the pump)
- the white wire ????
Since the line going to the well pump from the panel doesn't have a neutral, can I just put a cap on the white wire and tape it? Is it that simple?
Part 2. This kinda depends on the correct way to do part 1. I purchased a second CSR302 to connect it the same way for my Hybrid Heat Pump water heater. The water heater also only has a 220v 3-wire feed. I figure I can plug in the water heat to get it nice and hot; then move the power cable to the water pump. Plenty of hot water to take a couple quick showers. In emergencies remember.
The added issue here is it's a "heat pump" water heater; incredibly efficient but a byproduct is condensation. So I have a separate little pump on the floor to catch the water dripping. The pump is 110v and only draws 1.5A. Is it possible to tie this into the CSR302?
I was thinking of mounting a 110 metal outlet box on the bottom side of the CSR302 via a knockout. Power it with tapping off one of the black wires, ground wire, but now feed it the white wire for neutral. Yes, I would have to manually unplug the pump and plug it into this outlet when I'm using the generator.
Is this possible or just a bad idea from the start?
