Ordering Information
Tripp Lite's instant-read CT120 circuit tester detects wiring stability in standard 120 volt AC wall sockets. To test a circuit you plug the circuit tester into a receptacle and view the lighted 3 lamp status display for verification of correct wiring, open ground, open neutral, open hot, hot-ground reversal and hot-neutral reversal fault conditions. A sticker on the tester details lighting combinations for each wiring condition. Its portable design and easy to read lighted display makes the CT120 an excellent addition to any laptop carrying case, tool belt or workbench.
