How much does it cost to install a subpanel?

Subpanel installation in Ottawa typically costs between $800 and $1,500, depending on the amperage, location, and complexity of the installation. This price includes the subpanel itself, installation labor, and basic wiring, but doesn't include the ESA permit fee (around $75-100) or any additional circuits you might add afterward.

The cost breakdown varies based on several key factors. Panel amperage is the biggest cost driver - a 60-amp subpanel runs about $200-300 for the equipment, while a 100-amp subpanel costs $300-500. Installation location also matters significantly. Installing a subpanel in an unfinished basement with easy access to the main panel costs less than running wiring to a detached garage or second floor, which could add $300-800 in additional wiring costs.

Distance from the main panel affects both material and labor costs. If your electrician needs to run 50 feet of 60-amp feeder cable versus 10 feet, you're looking at an extra $200-400 in wire costs alone. The type of wiring required also impacts price - underground burial to a garage requires more expensive direct-burial cable and additional labor for trenching.

In Ottawa, ESA permits are required for all subpanel installations, and the work must be completed by a licensed electrician. The installation process involves connecting high-amperage feeder wires from your main panel to the subpanel location, which carries serious safety risks if done incorrectly. Many homeowners install subpanels to add capacity for workshops, garages, or home additions where running individual circuits from the main panel would be impractical.

Additional costs to consider include upgrading your main panel if it lacks sufficient capacity (adding another $1,500-3,000), concrete cutting for basement installations ($200-500), or electrical upgrades to meet current code requirements. If you're planning to add multiple circuits immediately after subpanel installation, factor in $150-300 per additional circuit.
