Backup Power Guides
Last updated:ByStandby Power Desk
Practical guides to buying backup power in the Greater Toronto Area. Every company count on these pages is computed from the Home Generator Index listing data at build time, and every price is quoted from a named source and credited where it appears, so each figure can be traced back to the installer, contractor or guide it came from.
Where Is a Transfer Switch Installed in a Toronto Home?
A transfer switch is installed at or beside the main electrical panel, where the utility supply meets the house circuits.
What Does an Automatic Transfer Switch Do?
An automatic transfer switch moves a home from utility power to a standby generator during an outage, and back afterwards, without the homeowner doing anything.
Using a Manual Transfer Switch in an Outage
A manual transfer switch is worked by hand, so someone at home must run the portable generator outdoors, connect its cord and move the switch.
When Does a Generator Quote Need a Panel Upgrade First?
A generator quote may need a panel upgrade first when the house has a fuse box, a panel of 100 amps or less, or no breaker space, per Kolji Bros. Electrical.
Can a Condo or Townhouse Have a Backup Generator?
A condo or townhouse can have a backup generator only where the owner controls outdoor ground and a gas line.
Transfer Switch or Interlock Kit for a Portable Generator
For a portable generator, Kolji Bros. Electrical's Ontario pricing puts an interlock kit at $400 to $800 supplied and installed, a manual transfer switch at $800 to $1,500, and an automatic transfer switch at $1,500 to $3,000.

What a Generator Service Visit Should Cover
