I have equipment that has 3 wires (red, black, green)
The wire run from the breaker box is 10-3 (red, black, green, white)
The equipment requires 220/240v. I'm just wondering if it's OK to leave the white wire capped off at the outlet?
Basically I have a red & black hot tied to the red and black (respectively) and ground to ground. The white (which is tied to the ground in the circuit breaker box) is just capped off by itself at the equipment.
Is this good, or should I cut the white off in the breaker box which would essentially make my 10-3 run of wire a 10-2?
