Multi-test Arc fault circuit interrupter tester
First Claim
Patent Images
1. A testing system comprising:
- a hand-held transmitter including an enclosure and having a plurality of prongs that plug into a receptacle electrically coupled to a selected branch circuit, the transmitter having a circuit within the enclosure that tests an arc fault circuit interrupter electrically coupled to the selected branch circuit by creating a pulse on the branch circuit that trips the arc fault circuit interrupter, the pulse being created bygenerating a timing period signal for generating simulated arc fault pulses by calibrating an internally calculated clock rate of a processor based on a received synchronization signal; and
outputting the simulated arc fault pulses at a timing period defined by the timing period signal output by the processor,wherein the transmitter has a second circuit within the enclosure that tests whether the receptacle is wired properly by indicating whether at least one of a hot wire, a neutral wire, and ground wire of the branch circuit is wired properly based on current flow through at least one of the hot wire, neutral wire, and ground wire.

Abstract
A testing system includes a hand-held transmitter that plugs into a receptacle electrically coupled to a selected branch circuit. The transmitter includes a circuit effective to test an arc fault circuit interrupter electrically coupled to the branch circuit by creating a first pulse on the branch circuit that is effective to trip the arc fault circuit interrupter. The transmitter can perform an additional test of determining whether the receptacle is wired properly.
