Abstract
A system for detecting the miswiring of an electrical appliance that includes a microprocessor having first and second input connections to sample signals on two different electrical power lines. The microprocessor further includes a third input connection for a neutral line. In an embodiment of the invention, there is at least one switch through which electrical power can flow into a load. The at least one switch is controlled by the microprocessor. In a particular embodiment, the microprocessor is configured to compare the signals sampled at the first and second input connections to determine whether the electrical appliance has been wired correctly.
