Standby Generator Installation across South Carolina

Standby Generator Installation in Charleston, SC

Hurricane Hugo in 1989 and storms since have left Charleston homes without power for days, and tidal flooding on the peninsula and in West Ashley adds risk. Standby generators with automatic transfer switches should sit on raised platforms above the flood elevation, in enclosures built for salt air and anchored against wind.

Historic homes may have wiring from many eras, and the city's Board of Architectural Review regulates visible exterior changes. Low-lying neighborhoods flood from storms and king tides, so elevating panels, meters and AC equipment is common.

Standby Generator Installation in Columbia, SC

Columbia's long, hot summers make losing air conditioning a real hardship, and storms, ice and hurricane remnants all cause outages. Many families choose natural-gas standby generators with automatic transfer switches sized to run central air, and Dominion Energy may need to upgrade the gas meter.

Older homes may have original wiring and small panels, and air conditioning runs hard for months, stressing older circuits. Homes in low-lying areas near creeks can face flood risk to panels and outlets.

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.

What size standby generator do I need?
