Standby Generator Installation across Mississippi

Standby Generator Installation in Gulfport, MS

After Katrina, many Gulfport homes were rebuilt to newer elevation rules, and standby generators there are usually placed on raised platforms that match the home's elevation, in enclosures built for salt air and anchored against hurricane winds. A natural-gas or propane unit with an automatic transfer switch can run central air through long post-storm outages.

Rebuilt and newer homes are often elevated, with meters, AC units and panels placed to stay above flood levels. Older inland houses may have original wiring and small panels, and salt air corrodes outdoor equipment across the city.

Standby Generator Installation in Jackson, MS

Ice storms like February 2021 and severe spring storms have left Jackson-area homes without power for days, and many families now choose natural-gas standby generators with automatic transfer switches, sized to run central air or heat. The gas meter may need upgrading for a whole-house unit.

Older homes in Belhaven and Fondren can have ungrounded circuits, cloth wiring or panels that were never sized for central air. Mid-century ranches often have 100 amp panels that are already full.

Standby Generator Installation in Hattiesburg, MS

Tornadoes in 2013 and 2017 and hurricane winds that reach this far inland have left Hattiesburg homes without power for days, and many families choose natural-gas or propane standby generators with automatic transfer switches, sized to run central air. Units must sit outdoors on a level pad with clearance from windows, doors and property lines.

Older homes in The Avenues often have original or patched wiring and small services, and many raised homes have wiring in crawl spaces. Mid-century homes may have full panels.

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.
