I did an inspection today in which a 4 wire cable came into the box and 2 cables, the red and black were connected to a 2 pole breaker 50 amp breaker (A/C unit), the ground wire was connected to the bus bar and the white neutral was cut and bent back, not attached to a bus bar. Is this standard with 240v not to have the neutral connected?
It all depends on the appliance. If the circuit goes to a central AC unit, then it is ok. If the appliance is a combination 240 and 120 unit (Example, electric stove burners are 240 but the lights and computer is 120, then a neutral is required.) My guess is that it goes to the AC unit.
Where is surprise?
thanks. surprise is in the northwest valley of metro phoenix.
I remember when Surprise was in the middle of nowhere on the way to Vegas. The only reason you stopped there was if you drove a gas guzzler like my 442 and you couldn’t make it quite into Phx, so you stopped in Surprise for some of their gas which must have had gold in it.
Three wire 240 VAC circuits do not require a neutral.
Examples ,welders ,some wood working equipment,most electric water heaters .
