What should your generator power during an outage?
Before choosing equipment, make a list of what matters most. For some homes, essential circuits are enough: refrigeration, lighting, a sump pump and a few outlets. Other properties may need a broader backup plan.
A generator must be sized for the loads it will supply, including equipment that needs extra current when starting. We'll discuss the electrical side of the plan and the circuits you want covered, then identify the appropriate installation scope.
Portable generator connection vs. permanent standby power
Portable generator with a properly designed connection
A portable generator can be used for selected backup loads when connected through an approved arrangement. If you want to connect it to your home's wiring rather than run individually approved plug-in devices, a suitable transfer mechanism is essential.
Never plug a generator into a household outlet to feed power back into the panel. Back-feeding can energise utility lines and endanger workers and neighbours.
Permanent standby generator
A permanently installed standby unit can be configured to supply selected circuits or broader loads, depending on system design and equipment capacity. The electrical work typically includes an appropriately designed transfer arrangement and connection to the home's distribution system.
Fuel supply, site preparation and generator equipment may involve additional trades or suppliers depending on the selected system. We'll clarify what is included in the electrical quote.
Why transfer switches matter
An approved transfer device keeps generator power separated from the utility supply. It is a fundamental safety requirement for permanently connected generator installations and many portable-generator-to-home configurations.
The exact arrangement depends on the type of generator, circuits being supplied, existing panel and applicable code requirements. This is not a DIY extension-cord workaround.
Our approach to backup generator installation
- Identify priority equipment. Tell us which appliances and systems you need during an outage.
- Review the electrical installation. We consider the panel, supply arrangement, load requirements and possible connection location.
- Plan the transfer equipment. The design must prevent unsafe back-feeding and suit the generator configuration.
- Coordinate the project. We explain the electrical work and any installation dependencies before scheduling.
- Complete the required electrical work and checks. Permanently connected generator installations require an ESA notification of work; the acceptance process depends on the project.
If you also need a panel update, we can assess it as part of the plan. See our electrical panel upgrade service.
How much does generator installation cost?
The price varies with the size and type of generator, electrical connection, transfer equipment and the complexity of the site. Cost can also change if the project needs panel modifications, a long cable route or work by a separate fuel-service contractor.
For an accurate estimate, let us know whether you already own a generator, the model if known, and which systems you want to back up.
Generator safety in an outage
Generators produce carbon monoxide and must never be operated inside a home, garage or other enclosed space. Follow the manufacturer's outdoor placement and operating instructions. Keep generators away from doors, windows and air intakes, and never use damaged electrical equipment or improvised home connections.
If a storm causes a wider outage, your electricity distributor is responsible for utility-network repairs. In Sarnia, Bluewater Power provides official outage reporting and updates.
Frequently asked questions
Can one generator power my whole house?
That depends on generator capacity, the home's loads and the transfer-system design. Many households prioritise selected circuits rather than every appliance at once.
Is a transfer switch necessary?
A safe, approved transfer mechanism is required for permanently connected standby generators. The appropriate equipment and requirements for your situation should be assessed by an electrical contractor.
Can I connect my portable generator directly to my panel?
Not with a homemade or back-feed connection. Any connection to home wiring must use a properly designed and approved method.
Do generator installations need ESA approval in Ontario?
A permanently connected generator requires an ESA notification of work. Your contractor can explain the relevant inspection and acceptance process.
Can you help if I already own the generator?
Tell us the make and model, the property details and how you hope to use it. We'll review whether an appropriate electrical connection is feasible.
Plan backup power before the next outage
A safe backup-power system is easier to design before the lights go out. Great Lakes Electric can help you work out the electrical scope and next steps for your Sarnia property.
