I purchased this pump to transfer water from a holding tank in a self remodeled travel trailer up to the sink. The pump is an "on demand" style where it will pump pressure in the water line up against a closed faucet. A pressure switch on the pump cuts off the power when the pressure limit is reached. When the faucet is opened the pressure drops and the pump starts up to deliver water flow to the sink.
The motor on the pump operates on 120VAC. As you can see the wires to the pump are discrete wires including the hot wire path through the pressure switch.
My question is about the proper way to wire up and deliver AC power to this type of unit?
Best Answer
The wire on the pump is not rated to be exposed or cord connected.
You will need to mount the pump inside an enclosure such as a Hoffman box or equivalent.
Then you can terminate a raceway or cable to the enclosure and the wiring will be protected inside.
Since RV's are covered by the National Electrical Code, this will satisfy the NEC.
Good luck!
