Description
The Trane KT-RT250 GFCI Receptacle Tester with LCD is a handheld electrical diagnostic part used to evaluate wiring conditions and ground-fault protection at standard outlets. It operates by plugging into a 120V and using internal circuitry to check voltage level, polarity, and ground integrity while simulating a fault condition to measure trip response time. It is typically used during commissioning, maintenance, and troubleshooting of electrical supply points in control panels, installations, and building power distribution circuits. It operates as a verification and safety-check tool within the electrical supply and control infrastructure in HVAC systems.
