Hi: Porter-Cable CPLMC7580V2C 7.5 HP 80 gallon industrial 2 stage compressor. Specs: Voltage/Hertz/Phase: 240/60/1 Horse Power: 11.00 peak, 7.5 run 30 Amps @ 240 Volts. Instructions say "minimum branch circuit requirement" : 30 amp. I'm leaning towrads using a 40 amp breaker, 8-2 wire w/ground. Does this seem right? I'm concerned if I used a 30 amp breaker with 10-2 wire it might trip the breaker when it kicks in. It's only about 35 to 40 feet away from the electric panel. Now also thinking about this idea: wire it up with a 50A breaker and 6AWG wire and NEMA 6-50 recepticle and put a NEMA 6-50 plug on the compressor. That way I can also use the recepticle for a Lincoln 220 welder that has a NEMA 6-50 Plug requiring 50 Amp circuit and a Lincoln 180C welder that came with a NEMA 6-50 Plug requiring a 40 AMP circuit. This would save me from running a line for the welders. I would never use the compressor or any of the welders at the same time. Just wondering if using a 50 AMP breaker is too much for the compressor by not providing enough safety by not being able to trip if or when needed. Thanks !
