Hello Member;
Looking for some confirmation. I am installing a subpanel in an attached garage. Approximately 70 ft from the main panel. I am using 10/3 wire to feed the subpanel. I am looking to connect 2 pieces of equipment to the subpanel. One machine is 30amp/250v ( machine A )and the other is 20amp/220v ( machine B ). These machines would not be used at the same time.
My question is if I wanted to add a third piece of equipment which is 10amp/220v ( machine C ) would it be possible to add this circuit to the subpanel. This third piece of equipment ,machine C would only be used at the same time with either machine A or B
Max current draw for machine A is 28 amps and machine B is 17 amps, machine C is 10 amps ( based on nec 430/ 430.148)
Nec 310.15 b states that at 90C 10/3 handles 40 amps
Machine A + C = 38 amps ( potential concern ???)
Machine B + C = 27 amps ( not a problem)
Would the above set-up be ok? Time delay 30amp breaker?
Thank-you for your help
