Dedicated Circuits for Home Appliances: When You Need Them

A dedicated circuit is a circuit that serves a single appliance or outlet. It has its own breaker in the panel and isn’t shared with other loads. Many high-draw appliances are required by code to have a dedicated circuit; others benefit from one for safety and performance. Here’s what homeowners in Coquitlam, Vancouver, Surrey, and the Lower Mainland should know, and when to call a licensed electrician to add or verify dedicated circuits.

Appliances That Need a Dedicated Circuit

The Canadian Electrical Code and local requirements typically require dedicated circuits for:

• Electric range / cooktop: Usually 40A or 50A, 240V.
• Electric dryer: Typically 30A, 240V.
• EV charger: Often 40A or 60A, 240V; see our EV charger installation article.
• Heat pump: Depends on unit size; see heat pump electrical requirements.
• Hot tub / spa: Usually 40A or 50A, 240V, with GFCI protection and often a disconnect.
• Air conditioner (central): Sized to the unit; often 30A–60A.

Refrigerators, freezers, and sometimes garbage disposals are also commonly put on dedicated circuits to avoid overloads and tripping when other kitchen loads are on. A licensed electrician can confirm what’s required and what’s recommended for your home.

Why Dedicated Circuits Matter

High-draw appliances that share a circuit with lights or other outlets can trip the breaker when they start or run. Sharing also increases the risk of overload and overheating. A dedicated circuit sized for the appliance avoids that and meets code. The electrician will run the correct wire size and install the right breaker; for 240V appliances, that means a double-pole breaker. All new circuit work requires a Technical Safety BC permit and inspection in BC.

Panel Capacity

Adding a dedicated circuit only works if your panel has space and capacity. Older 100A panels may have few spare breaker spaces and limited capacity for another 30A or 50A circuit. If you’re adding an EV charger, heat pump, or hot tub, your electrician may recommend a 200A panel upgrade so you have room for the new circuit and future loads.
