Backup generator installation in Cambridge
When the power goes out, the sump pump stops, the furnace fan stops and the freezer starts to warm up. A generator wired into the house through a transfer switch keeps the essentials going without extension cords through a window.
What we install
- Whole-home and essential-circuit standby generators
- Automatic transfer switches that start the generator for you
- Manual transfer switches and inlet boxes for portable generators
- Dedicated panels for the circuits you want backed up
- Wiring for the generator pad and controls
- ESA filing and inspection
Decide before you buy
- Which circuits you cannot go without
- Whether it should start on its own or you are happy to wheel one out
- Natural gas, propane or gasoline
- Where it can sit with proper clearance from windows and vents
Sized to what you need running
Homes near the Grand and Speed rivers, and anywhere with a high water table, lean heavily on their sump pumps, which makes backup power more than a convenience. We size the generator from the list of things you need running, and the electrical connection is priced after seeing the house. Gas hookups are done by a licensed gas fitter.
Who does the work
Cornerstone Electrician Cambridge works with licensed electricians. Where the job needs it, the work is filed with the Electrical Safety Authority and inspected.
Common questions about generator installation
- Why can't I just plug the generator into an outlet?
- Because it sends power backwards through your panel and out to the street, where it can injure utility workers and damage your equipment when the grid comes back. A transfer switch prevents that.
- How big a generator do I need?
- Enough for what you plan to run. A sump pump, furnace, fridge and a few lights need a much smaller unit than a whole house with central air. We work it out from your list.
- Who connects the gas line?
- A licensed gas fitter. The electrician handles the transfer switch and wiring, and the two are coordinated.
