Overload protection does not protect against short-circuits or ground-fault currents.To get licensed in Michigan, electricians are required to take an exam that covers such subjects as circuits, conductors, grounding, lighting and safety. An overload is where the current is more than the equipment ampere rating and the overload may result in overheating and damaging equipment. Overloads are not a fault condition, overloads happen when there is excessive current in the circuit. Section 430.6(A)(2) indicates the ampere rating (FLA) provided on the motor nameplate is used to size the overload protective devices that protects the motor, motor controller, and motor branch-circuit conductors. Section 430.6(A)(1) explains for a motor of this type, Table 430.250 that shows the full-load current (FLC) of motors, shall be used to determine the ampacity of conductors or ampere ratings of switches, branch-circuit short-circuit and ground-fault protection, instead of the actual ampere rating marked on the motor nameplate.
Article 430 covers motors, motor conductors, motor protection, motor controllers, motor control circuits, and motor control centers.
