Generator installation in Mississauga: what to expect
Outages in Mississauga 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 Alectra Utilities's lines.
Local notes: Mississauga
Aluminum wiring checks. If your home was built roughly between the mid-60s and late 70s, it's worth confirming what's in the walls. Pigtailing with approved connectors is often all that's needed.
Alectra Utilities. Mississauga is served by Alectra. Service upgrades need their disconnect/reconnect, which we book alongside the ESA permit.
