Capacity & service
The right capacity for the way your West Island home is evolving.
We assess the existing panel, service size and planned loads before recommending a panel change, a full service upgrade or an approved energy-management solution.
Start with the right question
A panel change and a service upgrade solve different problems. We review the equipment, breaker space, service size and the loads you plan to add before recommending either one. That assessment matters when a home is preparing for EV charging, electric heating, a spa, a larger kitchen or a major renovation.
The goal is not automatically 200A. It is the right capacity and equipment for the home’s actual demand and future plans.
Panel change vs. service upgrade
The interior distribution panel is replaced while the existing service capacity remains.
The home’s available capacity is increased, often from 100A to 200A when the load calculation supports it.
What to watch for
These conditions do not all lead to the same solution. They are reasons to have the system evaluated before choosing the work.
Repeated trips or noticeable changes under load can point to a circuit problem, a connection issue or insufficient capacity. Testing and a load review help identify the actual cause.
Heat, corrosion, unusual sound or odour deserves prompt attention. Avoid touching the equipment and call for an electrical assessment, especially if the condition is changing.
Older equipment or a full panel can make future work difficult. We review its condition, service capacity and planned circuits before explaining whether replacement is appropriate.
The brand alone does not determine the complete recommendation. Age, condition, breaker availability, visible concerns, planned demand and possible insurance requirements should be reviewed together.
Large new loads call for a residential load calculation. The result may support the existing service, point to an approved energy-management solution or justify a service upgrade.
A coordinated project
Electrilex handles the electrical work and the applicable utility coordination so each stage is clear.
We review the existing panel, service equipment, available space and the improvements you are considering.
Existing and planned electrical loads are considered before panel, service or energy-management options are recommended.
We handle the required electrical declarations and coordinate applicable Hydro-Québec disconnection and reconnection work.
The installation is completed carefully, circuits are identified and the finished work is reviewed with you.
Long-term responsibility
New panel installations include a 25-year manufacturer warranty and Electrilex’s 10-year labour warranty.
