A standby generator can restore power automatically through a permanently installed system. A portable generator generally involves manual setup and operation. The right choice depends on your essential equipment, whether someone will be home during an outage, available fuel and the property’s installation conditions.
For homes in Toronto, the GTA, Simcoe County and Muskoka, start with the backup-power priorities rather than the generator size. A carefully planned system should explain what will operate and what you will need to do during an outage.
List the equipment you want backed up
Consider refrigeration, heating equipment, sump or sewage pumps, well equipment where applicable, selected lighting and communications. Separate essential loads from equipment you would prefer to keep available.
Starting requirements and simultaneous operation matter as well as normal running demand. Do not choose a generator by adding a few nameplate figures without reviewing the equipment and transfer design. Some installations use load management to prioritize selected equipment.
When a standby system makes sense
A home standby generator is installed outside and connected through appropriate transfer equipment. With the system configured for automatic operation, it responds to an outage and supplies the planned loads once the generator is ready.
This can suit homeowners who want an automatic response or may be away when power fails. The design still determines the coverage: “whole-home” does not automatically mean every appliance can run together without limits.
Standby power is also different from an uninterrupted power supply. There is a transition while the generator starts and transfer occurs; equipment requiring uninterrupted operation needs separate consideration.
When a portable generator may fit
A portable generator may suit a limited backup plan when someone can safely position, start and operate it. Review storage, fuel handling, weather conditions and who is able to carry out the operating steps.
If it will supply the home’s installed circuits, an appropriate approved transfer arrangement must be designed and installed. Generator, inlet, cord and transfer equipment compatibility should be checked together. Never connect a generator to the home by backfeeding through a receptacle.
| Consideration | Standby system | Portable arrangement |
|---|---|---|
| Operation | Automatic with the selected compatible transfer system. | Generally requires a person to set up and operate it. |
| Installation | Permanent equipment, electrical integration and fuel coordination. | Portable equipment; supplying house circuits requires suitable installed transfer equipment. |
| Backup coverage | Defined by generator sizing, transfer design and any load management. | Defined by generator capability and the selected connection arrangement. |
| Ongoing responsibilities | Scheduled maintenance and monitoring of system readiness. | Safe placement, fuel, setup and maintenance. |
Plan placement and carbon monoxide safety
Fuel-burning generators produce carbon monoxide. Never operate a portable generator inside a home, garage or shed, or in a partly enclosed space. Health Canada advises keeping fuel-burning portable generators at least 6 metres from the home and its doors, windows and vents. Exhaust must be directed away from buildings and openings.
This portable-generator guidance is not a placement specification for a permanently installed standby unit. Standby placement must follow the selected manufacturer’s instructions and applicable installation requirements, with the property’s openings, clearances and site conditions reviewed.
Compare complete installed scopes
A standby proposal should identify generator equipment, transfer equipment, electrical work, mounting provisions and any load management. Establish who handles the fuel connection and whether excavation or restoration is included. Gas work should be coordinated with the appropriate qualified trade.
For a portable plan, include the compatible generator and any inlet, transfer equipment, cord and operating instruction. The generator purchase price alone does not describe the installed backup arrangement.
ESA requires a transfer device for a generator permanently connected to home wiring and a notification of work for that connection. Electric FX coordinates the ESA requirements for our electrical installation and provides acceptance documentation once the work is accepted.
Prepare for a backup-power consultation
- Property address and whether it is a primary home or seasonal property.
- Essential equipment and the loads you would like available.
- Photos of the closed panel and possible outdoor equipment locations.
- Available fuel and any existing generator or transfer equipment models.
- Whether someone can operate a portable system during an outage.
