Hello all,
So I'm an electrical engineer, but have limited construction experience. I understand concepts and I'm handy with the NEC and NFPA codes, but that's a far cry from how things actually are constructed.
My question comes from working out conduit sizing calculations. I would like to provide power feeds for multiple equipment in the same conduit between the electrical room and the room with the equipment. I know for larger power requirements each phase would be run as a separate single core cable per phase, but I'm wondering about loads that can be fed from a multi-core cable.
I've got some data sheets from cable manufacturers to see what the overall area of the cables are.
So lets say I have a 3phase pump that requires 3#10 and a #10CPC (ground), would this be a 3 core cable plus a separate single core ground cable, or would it be a 4 core cable? or?
What if there is also a neutral cable required?
thanks!
