CT80: AFCI, GFCI and AC Circuit Analyzer

Quickly checks for correct wiring of AC outlet load handling capabilities plus Outlet Tester functions

Circuit and wiring issues can introduce shock hazards (from grounding issues) and can compromise performance of machinery and equipment (from poor ground impedance, lack of sufficient voltage under load and/or high ground-to-neutral voltage). The CT80 is a GFCI and AC Circuit Analyzer which covers outlet load handling and outlet tester functions. Complete with AC test cord (standard North American 3-prong plug).
