What Size Electrical Panel Do I Need in Alberta?
Choosing the right electrical panel size is one of the most common questions Calgary homeowners ask before starting a renovation, adding an EV charger, or planning a solar installation. The wrong panel size creates safety risks, failed inspections, and costly rework. This guide covers everything Alberta homeowners need to know.
Common Electrical Panel Sizes in Alberta
Residential electrical panels in Alberta typically come in three sizes:
60 amp – Found in older Calgary homes built before the 1970s. This service is no longer adequate for modern electrical demand and most Calgary insurers require it to be upgraded. If your home still has 60 amp service, an upgrade is likely overdue.
100 amp – The minimum service size permitted under the Canadian Electrical Code for residential installations. Sufficient for smaller homes without high demand appliances, but limiting if you plan to add an EV charger, air conditioning, or solar system.
200 amp – The current standard for most Calgary homes. Provides sufficient capacity for modern appliances, EV chargers, solar systems, and heat pumps. New homes in Calgary are typically built with 200 amp service as standard.
Which Panel Size Does Your Alberta Home Need?
The right panel size depends on your current usage and future plans. Here are the most common scenarios we see in Calgary:
Stay at 100 amp if: Your home is small, you have no plans for high demand additions, and your current panel is in good condition with no safety concerns.
Upgrade to 200 amp if:
- You are installing an EV charger or plan to in the future
- You are adding air conditioning, a hot tub, or a sauna
- You are installing solar panels and want adequate busbar space
- Your current panel trips frequently or is over 25 years old
- You are developing a basement suite
- Your insurer is requiring an upgrade
When Do You Need a Service Upgrade vs a Panel Upgrade?
These two terms are often confused.
A panel upgrade replaces the electrical panel inside your home — the box with the breakers. This increases your available circuit capacity.
A service upgrade increases the power delivered to your home from ENMAX or Fortis Alberta. This involves upgrading the utility supply, meter base, and service mast. A service upgrade is required when you are moving from 60 amp to 100 amp, or from 100 amp to 200 amp service.
In most cases, a service upgrade and panel upgrade are completed together as a single project. Panel Upgrade Experts coordinates directly with ENMAX for disconnection, reconnection, and inspection — you do not need to contact the utility yourself.
