I am waiting delivery and setup of my PM 3520C lathe and decided that it would make sense to rearrange my shop and change the location of the lathe from where it is to a spot that would require a 12' - 15' cord instead of the 10' length I originally planned. My understanding of electrical and 220 V circuits is that a 15' 12-3 cord should not be a problem. The VFD Input Amp rating is 10A and VFD output to the 3PH motor is rated at 7.5A. Overall the circuit is a 20 A circuit.
Am I OK to use a 15' cord (might be able to get away with a 12' cord)?
