How many outlets do I need in my garage?

For a typical residential garage in New Brunswick, you'll need a minimum of one outlet per vehicle bay, but most homeowners benefit from 4-6 outlets strategically placed around the garage. The Canadian Electrical Code requires at least one outlet in attached garages, but this bare minimum won't meet most homeowners' needs.

Basic Requirements vs. Practical Needs

The CEC sets the minimum at one outlet for attached garages, but this was written decades ago when garages were just for parking cars. Today's garages serve as workshops, storage areas, and charging stations for everything from electric vehicles to lawn equipment. A well-planned garage should have outlets every 6-8 feet along the walls, similar to basement workshop requirements.

For a standard two-car garage, consider this layout: two outlets on the front wall (near the garage door opener and for seasonal decorations), two outlets on each side wall (for workbenches, tools, and equipment), and one outlet on the back wall. This gives you 6-7 outlets total, providing flexibility for current and future needs.

GFCI Protection and Circuit Requirements

All garage outlets in New Brunswick must have GFCI protection under TSANB requirements, as garages are considered wet locations. This protects against electrical shock from moisture, which is common in Maritime climates where snow, ice, and humidity create wet conditions. Your electrician will typically install GFCI breakers in the panel or GFCI outlets as the first outlet on each circuit.

Most garages need at least two 20-amp circuits to handle the electrical load. One circuit can serve general outlets, while a second handles higher-draw items like electric vehicle chargers, air compressors, or welding equipment. If you're planning an EV charger installation, that will require its own dedicated 40-amp circuit.

Special Considerations for New Brunswick

Given our harsh winters and frequent ice storms, many NB homeowners install outlets specifically for block heaters, battery tenders, and backup generators. Consider adding a 240V outlet if you might install a generator transfer switch or need heavy-duty equipment power. Coastal areas like Saint John and Moncton should use outlets rated for corrosive environments due to salt air exposure.

Installation and Permits

Adding new garage outlets requires a TSANB electrical permit, as this involves new circuits. The work must be done by a licensed electrician who will ensure proper GFCI protection, adequate circuit capacity, and code-compliant installation. Expect to pay $150-250 per outlet installed, depending on the complexity of running new circuits from your panel.
