Overview
Not a smart switch or a dimmer, the Leviton Decora Plus is a plain on and off rocker built for commercial use, with a quiet AC mechanism. It wires from the back or side and grounds by screw or clip.
Wiring flexibility is the reason electricians reach for it, with back and side terminals that take stranded or unstranded wire and two ways to ground. Motor loads are derated, so a fan or pump on the circuit needs checking against the reduced capacity.
Who it's for
Suits offices, shops and busy homes where a switch gets heavy daily use and stranded wire is common. People wanting to dim lights or control them from an app need a different device.
Pros and cons
- Back and side wiring terminals
- Accepts stranded or unstranded wire
- Two grounding options
- Full capacity on tungsten and fluorescent
- Motor loads derated
- Amp and volt figures only in the title
- Wallplate not listed
- Single-pole, no multi-location control
Performance notes
Full capacity holds for lighting and resistive loads, while motor loads are derated because their startup current stresses the contacts. Secure terminations matter most, and the back and side terminals let installers use whichever method suits the wire.
