A load protection system and a method of protecting a load. The load protection system includes a PLC transmitter module and a PLC receiver module, which are configured to communicate a plurality of bits of data, each bit transmitted near a zero-crossing of a voltage on the power lines supplying power to the load, in the form of a high frequency burst of pulses. The pulses are structured in two patterns. The first pattern serves to identify the start of the second pattern, and the second pattern includes the data. The first pattern is unique and not represented within the second pattern. The load may be a motor, and the data may include a parameter value representing a parameter of the motor.

A motor controller may evaluate the parameter value to determine whether to institute a warning or alert action, to shut the motor down, or to continue operating.
