The CT70 is an AC circuit load tester designed to quickly verify AC outlet load handling capabilities and perform outlet wiring diagnostics. It features selectable loads of 12, 15, and 20 Amps, measures both loaded and unloaded AC line voltage, and calculates voltage drop percentage and line impedance. The device includes outlet tester functions such as neutral-to-ground voltage measurement, hot/neutral/ground impedance testing, GFCI trip time and current detection, and identification of open or reversed wiring. With a large LCD display that provides color-coded pass/fail alerts and operates on AC voltages from 90.0 to 240.0V at frequencies of 45.0 to 65.0Hz, the CT70 is ideal for electricians and technicians performing circuit load verification and safety testing on standard 3-wire and GFCI receptacles.
