OK, my dad has this recirculating pump (Grundfos UPS 20-42) that kept the hot water on demand and hot at a moments notice and when the seperate timer died, he just disconnected it and he has to wait a little longer to get hot water at the sinks further from the heater than he used to...
Anyway, now he wants to connect a switch to it so it can be enabled at will but I'm not experienced with AC electrics (cars and PC's, that's different).
There are 5 wires involved and I'm not confident on how they need to be connected as the options ive tried seem to blow the breaker...
The pump has two wires, one red and one blue coming from it where the conduit/romex (what's the difference anyway?) feeds to the switchbox/housing, the ac feed offers green, grey and black wires.
At the hardware store, the guy said the green is ground and should be affixed to the housing as well as the ground on the switch, as for the rest it he said the black was hot and the grey was common. ? it seemed then, that either the red paired with the black and the blue paired with the grey or the other way round took care of the rest. not many other options, right?
Either the pump is bad ? or there are other options or something else, as both pairings pop the breaker after connecting and enabling the breaker and trying the switch.
What am i missing? this seemed simple but its not responding that way.
Advice would be appreciated, thanks in advance!
