We are working on a project where the equipment is coming from overseas. I believe that this equipment would fall into the category of Industrial Machinery. Attached is nameplate data. The nameplate list kW, Volts, Amps and SCCR rating. I would assume that this is the FLA rating and would size circuit at 125%. 670.4 - Supply conductors and Overcurrent Protection isn't quite that simple. It states states (A) Size. The size of the supply conductor shall be such as to have an ampacity not less than 125 percent of the full-load cur- rent rating of all resistance heating loads plus 125 percent of the full-load current rating of the highest rated motor plus the sum of the full-load current ratings of all other connected motors and apparatus, based on their duty cycle, that may be in operation at the same time.
What is interesting is that the equipment with 100A nameplate has (2) 50A breakers directly off the main input terminal block. I would normally feed with 125A based on 125% of nameplate, but with the (2) 50A breakers, I wouldn't think that would be necessary and just feed with 100A.
Looking or some input on this. There are more tools coming and have no confidence in equipment matrix and relying on nameplate data when equipment lands.
