Generator installation in Oshawa: what to expect
Outages in Oshawa come with ice storms and summer thunderstorms. Even a few hours without power matters if your basement relies on a sump pump or someone at home relies on medical equipment.
We size the generator from a load assessment — essential circuits only, or the whole home — install the automatic transfer switch, and coordinate the gas connection with a licensed gas fitter.
Prefer a portable generator? A properly installed inlet and interlock lets you power the panel safely, without dangerous back-feeding into Oshawa Power's lines.
