Switches, dimmers and receptacles all need a secure home in the wall. Gang electrical boxes provide that enclosure, holding devices firmly in place and containing the wiring behind them. Selecting the right size keeps connections uncrowded and makes it easier to add smart dimmers, occupancy sensors or extra controls when you upgrade your lighting.
Types and Options
Single-gang boxes hold one device, while multi-gang boxes group several switches or outlets side by side under one cover plate. Steel boxes can be joined together and are often used with conduit or armoured cable, whereas non-metallic versions are light and quick to install. New work boxes nail to studs in open walls, and old work boxes with retaining tabs clamp into existing drywall during renovations.
Where to Use Them
Used in kitchens, living rooms, entryways, basements, offices and commercial spaces wherever switches, dimmers or receptacles are installed.
