A monitor for detecting miswiring in standard 3-spade AC electrical outlets. The monitor includes a housing, prongs for insertion into the outlet to be tested, outlet ports for an external plug, and a banana jack for a wrist strap or other anti-static device. If the outlet is properly wired, a lamp will illuminate. If, however, the outlet is miswired, one of two silicon controlled rectifiers will shunt current around the lamp, extinguishing it, indicating to the user the presence of a faulty outlet. A junction field effect transistor is also provided to activate one of the silicon controlled rectifiers when one particular miswiring condition is present.
