How do I know if my electrical panel needs more circuits added?

If you're relying on extension cords, tripping breakers regularly, or planning any renovation, your New Brunswick home likely needs additional circuits — here's how to assess what you need.

Clear signs you need more circuits:

• Extension cords and power bars everywhere — these are temporary solutions being used as permanent wiring. Each regularly used power bar often indicates a missing dedicated outlet/circuit
• Breakers trip when running multiple appliances — especially in kitchens, bathrooms, and workshops
• Only one outlet on an entire wall or room — common in older NB homes where bedrooms might have just 1-2 outlets
• No dedicated circuits for major appliances — code now requires separate circuits for: microwave, dishwasher, garbage disposal, each bathroom, laundry room, furnace, and kitchen countertop outlets
• You're adding electric baseboard heaters — each heater needs its own dedicated circuit

Modern CEC requirements vs older NB homes:

| Area | Current Code Requirement | What Older NB Homes Have |
|------|-------------------------|-------------------------|
| Kitchen countertop | 2 dedicated 20A circuits | Often 1 shared 15A circuit |
| Each bathroom | Dedicated 20A circuit | Usually shared with bedroom |
| Laundry room | Dedicated 20A circuit | Often shared |
| Garage | At least 1 dedicated circuit | Sometimes no circuit at all |
| Outdoor outlets | At least 1 front, 1 back | Often none |
| Bedrooms | AFCI-protected circuits | Standard breakers, shared circuits |

Panel capacity check:
Your electrician will check if your panel has available breaker spaces. Options if the panel is full:

• Tandem breakers: Fit two circuits in one breaker space — only if the panel is rated for them (check the panel label)


• Sub-panel: Add a secondary panel fed from the main panel — good for workshops, additions, or garages


• Panel upgrade: Replace with a larger panel with more spaces — the best long-term solution

Costs for adding circuits in New Brunswick:

• Single new circuit (outlet to panel): $300-$600


• Dedicated kitchen circuit: $400-$700


• Sub-panel installation: $1,500-$3,000


• Full panel upgrade with additional circuits: $3,000-$6,000


• TSANB permit: $100-$200

When to act: If you're planning any renovation, that's the ideal time to add circuits — walls are already open and wiring is accessible. Adding circuits after finishing walls costs significantly more due to fishing wire through closed walls.
