What's different about generator installation in Marietta
A portable generator connected through an outdoor inlet and panel interlock covers essentials, while a natural-gas standby generator with an automatic transfer switch runs automatically. Generators must run outdoors and away from windows. Marietta Power, Georgia Power or Cobb EMC owns the service depending on the address, and permits come from the City of Marietta or Cobb County.
Historic homes can have knob-and-tube or cloth wiring, and mid-century homes often have 100 amp panels. Newer subdivisions add EV chargers and generators.
