Learn how to install a 3G dimmer for 120W linear lighting with a smoked bronze switch plate. Step-by-step wiring and mounting guidance.

Quick answer

Install the 3G dimmer by switching off power, wiring each dimmer module to its 120W linear load, and securing the smoked bronze plate. Follow the step-by-step process below for a safe, clean fit.

Why the 3G dimmer suits 120W linear lighting

The 3G dimmer is designed for 120W linear lighting, which often uses LED strips or linear fixtures. Each of the three rotary dimmer modules controls its own circuit, so you can adjust separate zones or groups from one plate. The smoked bronze finish adds a tactile, industrial look that pairs well with modern interiors.

Wiring considerations for multi-gang dimmers

Because this is a 3-gang dimmer, you will have three separate load circuits. Ensure each circuit's total wattage does not exceed 120W. If you are replacing an existing switch, note the wiring configuration—each dimmer module needs its own live, neutral (if required), and switched live connection. If your setup uses a different wiring standard, consult a qualified electrician.

Installation steps

Turn off power and verify: Switch off the circuit breaker and use a voltage tester to confirm no power is present at the switch box. This is non-negotiable for safety. Always double-check with a tester, even if the breaker is off.
Remove the existing switch plate: Unscrew the old plate and carefully pull the switch out. Take a photo of the wiring before disconnecting to reference later. A photo prevents confusion when rewiring.
Disconnect and prepare wires: Disconnect the old switch wires. Strip the insulation about 3/8 inch from each wire and ensure no frayed strands remain. Clean, straight wire ends make secure connections.
Connect the dimmer modules: Wire each of the three dimmer modules to its corresponding load (max 120W per module) and the live supply. Use the terminal screws and ensure each connection is tight. Loose connections can cause flickering or overheating.
Mount the dimmer into the box: Carefully fold the wires into the back box, align the dimmer with the mounting holes, and screw it in place. Avoid pinching wires. Ensure the dimmer sits flush against the wall for a clean finish.
Attach the smoked bronze plate: Place the brushed solid metal plate over the dimmer and secure with the provided screws. Do not overtighten, as this can strip the threads. Hand-tighten and then give a quarter turn with a screwdriver.
Restore power and test: Turn the breaker back on and test each dimmer module. Rotate each knob to confirm smooth dimming and no buzzing. If a module doesn't work, recheck the wiring for that circuit.
