Can I have two electrical panels in my house?

Yes, you can absolutely have two electrical panels in your house. This is actually quite common in Ottawa homes, especially larger properties, homes with additions, or those with specific electrical needs like workshops or EV charging.

There are several scenarios where dual panels make sense. The most common is a main panel and subpanel setup, where your main electrical service enters through a 200A panel, and a smaller subpanel (typically 60A to 100A) feeds a specific area like a basement workshop, garage, or home addition. This allows you to distribute power more efficiently and keeps circuits organized by area.

Another common configuration in Ottawa is having separate panels for different purposes - for example, your main house panel plus a dedicated panel for a hot tub, pool equipment, or a detached garage. Some homeowners also install a separate panel specifically for backup generator connections, which automatically switches power sources during outages.

ESA requirements are straightforward but important. Each panel must be properly grounded and bonded, with appropriate clearances (1 meter in front, specific side clearances depending on the installation). The total amperage of your subpanels cannot exceed your main service capacity - so if you have 200A service, your main panel plus any subpanels must stay within that limit. All installations require ESA permits and inspections.

Installation costs in Ottawa typically range from $800 to $1,500 for a basic subpanel, depending on the amperage, distance from the main panel, and complexity of the wire run. If your main panel is already at capacity, you might need a main panel upgrade first, which adds $2,000 to $3,500 to the project.

The key safety consideration is that all electrical panel work must be done by an ESA-licensed electrician. This isn't a DIY project - improper installation can create fire hazards, electrocution risks, and will definitely fail ESA inspection. Your electrician will determine the right size subpanel, proper wire gauges, and ensure everything meets Ontario Electrical Safety Code requirements.
