Electrical entrance replacement

The service entrance brings power from the utility grid to your installation, while the panel distributes that power to the building’s circuits. Modifying the service entrance can increase available capacity, for example from 100 A to 200 A. Replacing the panel can improve safety and provide more circuit spaces without, on its own, increasing service capacity. A damaged or outdated service entrance can also be replaced at the same capacity.

A capacity increase may be necessary when the building’s needs exceed what the existing service can supply. This can happen when adding electric heating, a heat pump, a hot tub, a pool heater or other major equipment. We assess existing loads and new equipment before recommending a 200 A service. Adding an appliance does not automatically require this upgrade.

Upgrading an electrical service entrance from 100 A to 200 A generally costs between $3,000 and $4,000 at Lumineau Électrique. This type of project includes modifying the service entrance and installing a new panel suited to the planned capacity. The price varies with cable lengths, the desired number of circuits and working conditions. The quote details the components being replaced, connections and required work.

Yes. When the work requires Hydro-Québec’s involvement, we handle the arrangements and coordination needed for our portion of the work. We organize the intervention and explain the planned steps, including shutting off and restoring power. Scheduling depends on the project and coordination with Hydro-Québec.
