200 A electrical service entrance and panel upgrade on the North Shore
Rayon Électro replaces and upgrades electrical service entrances and residential or commercial panels in Deux-Montagnes, the Basses-Laurentides and across the North Shore. Whether your panel is showing its age or your electrical needs are growing, we help you get back to a solid, safe foundation.
When should an electrical panel be replaced?
A panel may need replacing when it ages, no longer meets your needs or shows signs of weakness. A replacement can also be useful to prepare for future work, such as adding power-hungry appliances or an EV charger.
Service entrance or panel: what is the difference?
The electrical service entrance covers everything that brings power to the building: the connection, the mast, the meter base and the supply wiring. The electrical panel comes next: it distributes that power to the various circuits of the house or unit.
The two are often handled together. Increasing the available capacity usually means reviewing the service entrance at the same time as the panel, otherwise the new panel would remain limited by the existing supply.
200 amp service entrance and 100 A to 200 A upgrade
Moving from a 100 amp to a 200 amp service entrance is the most common residential upgrade. It becomes relevant when the available capacity no longer keeps up: adding a heat pump, a spa, extra heating, an EV charger, or extending the house.
- Replacement of the service entrance and panel
- Upgrade from 100 A to 200 A
- Meter base, mast and supply wiring
- Circuit redistribution and labelling
- Preparing capacity for an EV charger
The actual need depends on your installation and how you use it: we assess it with you before making any recommendation. The final connection is handled by Hydro-Québec, with whom the work is coordinated when required.
Signs of overload or ageing
- Panel that trips regularly
- Old fuses or breakers
- No room left for new circuits
- Traces of heat or wear
- Need for additional capacity
A recurring breaker problem can also point to a repair need: see our electrical repair page.
Adding capacity
New appliances, an extension, an EV charger: many projects call for more electrical capacity. We adapt the service entrance, the panel and the distribution accordingly.
Residential and commercial work
We work on the service entrances, panels and distribution boards of homes as well as commercial units. For business needs, see our commercial electrical page.
Panels and EV chargers
Installing an EV charger often depends on the capacity of your panel. We assess both together. See also our EV charger installation page.
Assessment process and safety
Before any replacement, we assess the condition of the installation and your needs. Depending on the situation, an upgrade to standard or a permit may be required; we tell you clearly when that is the case. Our priority remains clean, safe work.
Frequently asked questions
What is the difference between the panel and the service entrance?
The service entrance brings power to the building (connection, mast, meter base); the panel then distributes that power to the circuits. Both are often upgraded together.
Do I have to move up to 200 amps?
Not necessarily. It depends on your installation and how you use it. We assess the situation before recommending an upgrade.
Is a permit or a code upgrade always required?
Not in every case. Depending on the work and the condition of the installation, an upgrade to standard or a permit may be required; we tell you beforehand.
Do you work on residential and commercial installations?
Yes, we replace and upgrade residential and commercial service entrances and panels on the North Shore.
