I am installing outlets for a 460 3 phase welder 37 amp 60% duty cycle.
Per 630.11A .78 x 37 = 28.86 amps calculated load
Conductor would be sized #10 per 310.16
Overcurrent protection would be 60 amp breaker max
My question is would I use 30 amp outlets sized to the branch circuit wiring (was planning on using the Meltric with the built in disconnect.)
Spoke to the welder manufacturer tech support and they recommended 60 amp recpt.
