What size breaker and wire do I need to run power to an outdoor kitchen?

Most outdoor kitchens in the GTA require at least two dedicated 20-amp circuits on 12-gauge wire, but the exact requirements depend on your appliances — a setup with an electric grill, refrigerator, and blender can easily demand 40 to 60 amps of total capacity across multiple circuits. Your electrician will perform a load calculation based on your specific appliance list before sizing the breaker and wire.

A basic outdoor kitchen with a countertop outlet for a blender and a dedicated outlet for a bar fridge can run on a single 20-amp circuit using 12/2 NMD90 wire run through outdoor-rated conduit. But the moment you add higher-draw appliances — an electric smoker (1,500W), a rotisserie (1,800W), an outdoor pizza oven (2,000W+), or an electric griddle — you need additional dedicated circuits to avoid chronic breaker trips. Each high-draw appliance should have its own dedicated 20-amp circuit at minimum. If you are installing an outdoor electric range or built-in electric grill, you may need a 30 or 40-amp circuit on heavier gauge wire (10/3 or 8/3).

For outdoor kitchens with substantial electrical demands, many electricians recommend installing a sub-panel at or near the outdoor kitchen rather than running multiple individual circuits back to the main panel. A 60-amp sub-panel fed by 6/3 wire gives you room to distribute power across several circuits locally, and it makes future additions much easier. The sub-panel must be installed in a NEMA 3R weatherproof enclosure rated for outdoor use, mounted at a code-compliant height, and bonded properly to the grounding system.

Every single outlet in an outdoor kitchen must be GFCI-protected — no exceptions. This applies whether the outlet is under a covered pergola or fully exposed to weather. Use in-use weatherproof covers on all receptacles so the seal is maintained even when appliances are plugged in. All wiring must run through approved outdoor conduit (rigid PVC or rigid metal), and any underground runs must be buried to 48 inches to clear Toronto's frost line. The conduit entries into boxes and enclosures need proper weatherproof fittings and sealant to prevent moisture intrusion.

Lighting is another consideration — most outdoor kitchens need task lighting over the prep and cooking areas plus ambient lighting for the dining space. Plan for a separate lighting circuit controlled by a weatherproof switch. LED fixtures rated for wet locations are the standard choice, and dimmer-capable models let you adjust the mood for evening entertaining.

Budget $2,500 to $6,000 for the electrical portion of an outdoor kitchen in the GTA, depending on the number of circuits, distance from the main panel, and whether a sub-panel is involved. An ESA permit is required, and your electrician coordinates the inspection.
