Hi all,
Looking for a little advice with an electrical question. I have a homebuilt Pentz design cyclone DC with a 220V 5hp Baldor motor. I have it on a 20 amp circuit. I wanted to make sure I'm not pulling too much current so I hooked up an ammeter to each leg of the circuit. Here are the numbers:
Red leg: 156.2 A max, 10.9 nominal
Black leg: 151.4 A max, 10.6 nominal
The max values are the peak numbers from my ammeter at startup. I'm not too worried about those values since they are momentary. But are the nominal values ok? I guess my question is whether a 20 amp circuit is 20 amps on each leg or both combined? If it's a combined value then I'm overloading the circuit.
These measurements were done with the DC wide open (no resistance) so this should be the highest values I ever get.
Thanks,
Dave
