An overhead entrance uses suspended cables between a Hydro-Quebec pole and your building, while an underground entrance passes underground via a buried conduit. The underground entrance offers better aesthetics and increased protection against weather, but installation is more expensive. The overhead entrance remains more economical and easier to maintain.
Several signs indicate a service entrance needs replacement: worn or bare cables, damaged meter box, visible corrosion, frequent overheating, regularly tripping breakers, or if your installation is over 25-30 years old. A professional assessment determines the exact condition of your entrance.
The cost varies depending on the type of entrance (overhead or underground), distance to cover, capacity required (100A, 200A, 400A), and site specifics. A typical residential overhead entrance costs between $2,500 and $5,000, while an underground entrance can cost between $5,000 and $12,000. We offer a free on-site evaluation with a detailed quote.
Yes, replacing a service entrance requires coordination with Hydro-Quebec for power disconnection and reconnection. As an approved electrical contractor, we handle all administrative procedures with Hydro-Quebec for you, including authorization requests and work scheduling.
For an average home with standard equipment, a 100A to 200A entrance is generally sufficient. If you plan to install an EV charging station, a heat pump, or if you have a large home with multiple electrical appliances, a 200A or 400A entrance is recommended. We evaluate your current and future needs to recommend optimal capacity.
