I have a situation where the EE speced a 200A safety switch fused at 110A for CU-1. The equipment arrives and it turns out CU-1 is actually two units that work in tandem. MOCP for each unit is 40A. While composing a RFI I sited 440.22(C). Although this is in chapter III of 440, upon reading 22(C) the highlighted areas below threw me:
Where maximum protective device ratings shown on a manufacturer?s overload relay table for use with a motor controller are less than the rating or setting selected in accordance with 440.22(A) and (B), the protective device rating shall not exceed the manufacturer?s values marked on the equipment.
Did I site the correct article?
Thanks
