Cities
Electrical contractors who install standby generators, transfer switches and generator inlets, so a home can run safely through an outage. Choose your city to see the pros.
Before you hire
A generator wired into your home needs an approved transfer switch, fitted under a permit, so it can’t feed power back into the lines. Plan it before you buy.
Get written quotes from at least three contractors for the same work, and check references from recent clients.
Put it in a written contract: the work, price, deposit, start and finish dates, warranty, permits and clean-up. Paying cash to skip it leaves you no recourse.
