ABSTRACT:
An apparatus and method for making fault interrupter receptacles tolerant to miswiring errors. By employing redundant sense elements plus a special switch configuration, the device obtains a symmetry that makes it unnecessary to designate specific line and load terminals. The addition of open neutral protection, ground assurance, transposed conductor protection and end-of-life protection provides enhanced performance with the addition of only a few parts relative to a conventional fault protection unit.
