can lead to electrical shocks, fires, or damage to equipment. Since garages often contain

flammable materials like gasoline, solvents, or paint, proper wiring and installation are

critical to prevent hazards.

Key Alberta Electrical Code Requirements for Garage Wiring

When planning or inspecting garage wiring, certain code requirements stand out:

Dedicated Circuits for Garage Outlets

According to the Alberta Electrical Code, garages typically require dedicated circuits for

their outlets. This means outlets should be connected to a circuit separate from the rest of

the home to prevent overloads. Most commonly, a 20-amp circuit breaker is

recommended for general-purpose receptacles in garages, ensuring enough capacity for

power tools, chargers, or other equipment.

Ground-Fault Circuit Interrupters (GFCIs)

Safety devices like GFCIs are mandatory for garage receptacles. These devices quickly cut

power if they detect a ground fault, preventing electrical shock hazards. The Alberta

Electrical Code mandates GFCI protection for all garage receptacles, especially because

garages can be damp or exposed to moisture, increasing the risk of shock.

Proper Wiring Methods and Materials

Garage wiring must use materials and methods approved by the Alberta Electrical Code.

This includes:

Using cable types suitable for the environment, such as non-metallic sheathed cable

1.

(NM) or conduit in exposed areas.

Ensuring cables are protected against physical damage, for example by running

2.

wires through conduit or behind walls.

Following color-coding rules for wires to avoid confusion during installation and

3.

maintenance.

Lighting Requirements

Adequate lighting is essential in a garage. The code specifies minimum lighting levels and

the types of fixtures acceptable for garage use. Typically, lighting should be mounted

securely and protected from potential damage.

Grounding and Bonding in Garage Wiring

Grounding is a vital safety aspect covered extensively in the Alberta Electrical Code. For

garages, proper grounding ensures that any stray electrical current has a safe path to

earth, reducing the risk of shocks and fires.

Metal Boxes and Conduits

If metal electrical boxes or conduits are used in the garage, they must be properly bonded

to the grounding system. This prevents the metal parts from becoming energized in the

event of a fault.

Ground Rods and Electrode Systems

Depending on the garage’s wiring setup and whether it has a separate subpanel,

grounding electrodes such as ground rods might be required. The Alberta Electrical Code

outlines the specifications for these grounding electrodes to ensure effective grounding.

Common Mistakes to Avoid When Wiring a Garage in Alberta
