Specifications

Pro-Tip: Receptacle testers are excellent for identifying wiring mistakes, but they cannot detect the quality of your ground or the presence of multiple hot wires on a single circuit. If the RT110 indicates "Correct" but you are still experiencing electrical interference or flickering lights, consult a licensed electrician to perform a comprehensive load test and ground resistance check.
