Extech Instruments CT70 AC Circuit Load Tester

THE ISSUECircuit and wiring issues can introduce shock hazzards (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. In addition, fire can result from the heat generated by high resistance points in a circuit. Proper wiring practices have been shown to greatly increase power quality performance. Electricain's require a test instrument to quickly check an AC outlet for load handling capabilities plus outlet tester functions including GFCI/EPD testing.THE SOLUTIONExtech Instruments has designed the CT70 AC Circuit Load Tester specifically for this application. It quickly inspects and detects circuit and wiring problems such as poor ground impedance, false grounds, missing ground fault protection, low voltage availability under load and high ground-to-neutral voltage. In addition, the CT70 tests GFCI and EPD circuits. The color-coded display changes from blue to red, providing a visual alert when a problem is detected.
