Standby Generator Installation across North Carolina

Standby Generator Installation in Charlotte, NC

Ice storms in the Piedmont can coat Charlotte's tree canopy and bring down lines across the city, leaving some neighborhoods without power for days. A natural-gas standby generator with an automatic transfer switch is a popular choice for families who work from home or care for relatives, and Piedmont Natural Gas may need to upgrade the gas meter.

Older ranch homes often have 100 or 150 amp panels, sometimes Federal Pacific equipment. New homeowners frequently add EV chargers and generator inlets.

Standby Generator Installation in Raleigh, NC

Raleigh homeowners who remember Hurricane Fran in 1996 or the December 2002 ice storm, when trees came down across the city and outages lasted days, often choose a natural-gas standby generator with an automatic transfer switch. Dominion Energy North Carolina, formerly PSNC, may need to upgrade the gas meter for a whole-house unit.

Older in-town homes may carry original or patched wiring, while mid-century ranches often have panels with little spare space. Rapid growth brings steady demand for EV chargers, generator hookups and circuits for additions.

Standby Generator Installation in Wilmington, NC

After Hurricane Florence cut Wilmington off by road for days in 2018 and left most homes without power, many families added standby generators with automatic transfer switches, sized to run central air. Near Wrightsville Beach, Carolina Beach and the Cape Fear River, units should sit on raised platforms above flood levels, in enclosures built for salt air and anchored against wind.

Historic homes can have knob-and-tube or cloth wiring, and humidity and termites can damage old insulation. Mid-century homes may have panels insurers question, and coastal homes face salt air.

What standby generator installation involves

Unlike a portable generator, a standby unit sits on a pad outside the home, runs a self-test each week, and takes over within seconds of an outage without anyone being home. It can power selected circuits or, if sized for it, the whole house including central air.

Installation combines electrical, fuel and site work: an automatic transfer switch at or near the panel, a gas line or propane tank sized for the unit, and a placement that meets the manufacturer's and local code clearances from windows, doors and property lines.
