Sub Panel Installation
As your electrical needs grow—whether from adding a garage, finishing a basement, or setting up a workshop—you might find your main electrical panel running out of space. That’s where a subpanel comes in. A subpanel (or secondary panel) is a smart, practical solution for expanding your electrical capacity while keeping things safe and organized.
What Is a Sub-Panel?
A subpanel is a smaller electrical distribution panel that connects to your main service panel. It receives power from the main panel and distributes it to specific circuits in a designated area of your home or property. It has its circuit breakers, doesn’t increase the total power supplied to your home but redistributes it more efficiently, and is often used in detached garages, basements, additions, rental suites, or workshops.
Why You Need a Sub-Panel?
If your main panel is full, a subpanel allows you to add more circuits without replacing the main panel entirely. New spaces like a finished basement, home office, or a secondary suite often require dedicated circuits. A sub-panel makes wiring and circuit management more localized. For garages, barns, or garden suites, installing a subpanel allows you to control power distribution independently at the second location. It helps isolate specific electrical zones, making it easier to troubleshoot or shut off power when necessary. The Canadian Electrical Code requires proper load distribution and circuit separation in some renovation or upgrade scenarios. It may be the safest and most compliant solution.
