Dedicated 20 Amp Garage Circuit Done the Right Way

Most garages are underpowered. One shared circuit trying to handle a fridge, a compressor, power tools, and whatever else you've got going - it's a recipe for tripped breakers and headaches. A dedicated 20 amp circuit fixes that. It gives your garage its own line, so everything runs the way it's supposed to without affecting the rest of the house.

Here's what this kind of job actually involves. We ran conduit through the exterior wall, feeding power from the panel out to the garage. The conduit work on the exterior is clean and properly secured - no shortcuts, no exposed wiring just hanging loose. Getting that routing right matters, especially where the conduit transitions through the foundation and into the structure.

Inside the garage, we installed a 110V quad outlet box mounted to the framing with rigid conduit feeding it from above. We also added a dedicated light switch - housed in a metal gang box with armored conduit - so the space has proper, controlled lighting separate from the power circuit. Everything got tested with an outlet tester before we called it done. That step isn't optional for us.

The result is a garage that's actually built for real use. Whether you're running a table saw, keeping a spare fridge cold, or just want reliable power for a workbench - this is the setup that handles it without tripping breakers or creating a safety issue. That's what a proper outlet installation and light switch installation looks like when it's done right.

Garages get overlooked when it comes to electrical, but they don't have to be an afterthought. If yours is running off one overloaded circuit or you're constantly resetting breakers, it's worth getting it sorted out properly.
