E N D
Design Procedure • Get specification • Find the required load -> current • Choose the cable • Verify the voltage drop • Choose the raceway (if any) Don’t forget 20%
Design Procedure (Motor) • Get specification (P) • P -> Find input Power by dividing efficiency -> Nominal Current • Cable -> 1.25*In • Ground -> • CB -> 2*In (don’t like)
