Method and system for detecting miswiring of a power supply for a domestic appliance

Abstract:

A system for detecting miswiring in an AC power supply for an appliance may comprise a phase sensor sensing the phase difference between the first and a second hot line powering heavy electrical loads therebetween, and a control module coupling to the phase and voltage sensors. The control module may identify a fault condition and may disconnect different electrical loads from the power supply in the fault condition.
