ABSTRACT:
A polarity identifier and fault tester for testing three wire grounding type receptacles quickly and in a foolproof manner. A plurality of condition indicators are provided which are activated in a multiplicity of different patterns each representing a different specific condition. Each condition indicator is a go no-go type thereby eliminating the need for interpretation by the operator other than to compare any abnormal pattern with a chart to identify the particular fault condition in the outlet connections. The tester has but a single control comprising a push button switch that requires no connection to ground or other object other than the insertion of the three prong tester plug into the outlet to be checked. A total of 27 possible conditions can be checked and identified as proper or improper by observing the indicator pattern before and upon closing the single control button.
