All of the following are basic elements of a motor circuit except?

In a basic motor circuit, the primary components typically include an overload relay, a contactor, and a power supply. The overload relay is essential for protecting the motor from excessive current that could lead to overheating and damage. The contactor serves as an electrically controlled switch that allows or interrupts the flow of power to the motor. The power supply provides the necessary voltage to operate the motor.

In contrast, a motor control center is not considered a basic element within the simple definition of a motor circuit. A motor control center is a large assembly that houses a variety of motor starters, protective devices, and control circuits used for the centralized control of motors. Its function goes beyond the essential components required to operate a single motor, making it more of a comprehensive solution suited for managing multiple motors rather than an inherent part of a basic motor circuit. Thus, the motor control center stands apart from the fundamental elements typically included in a single motor circuit.
