This video demonstrates how to replace an existing switch or dimmer and install a Leviton Trimatron Rotary Dimmer. It shows how to identify the hot wire, wire the dimmer, and test the installation.
Installation takes about 15 minutes and begins by turning off power at the circuit breaker, removing the old device, and identifying the hot wire using a voltage tester. Wiring steps differ slightly between models: RNL06 uses two black leads for hot and load connections, while RDL06 uses a black lead for hot and a red lead for load, with an additional labeled red wire for 3-way applications.
Please follow local electrical codes and consult an electrician if needed.
