![]() ![]() 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. ![]()
