Missouri weather doesn't ask permission. A standby generator with an automatic transfer switch restores power in seconds — no cords, no trips outside in the storm.
Portable vs. standby
Portables are cheaper but need refueling, manual hookup and a safe inlet. Standby units run on natural gas or propane, start themselves and power the whole house.
Sizing
- 10–14 kW: essentials — fridge, furnace, sump pump, lights
- 18–22 kW: most of the home including one AC unit
- 24–26 kW+: whole house with two AC units or an EV charger
The transfer switch
An automatic transfer switch sits between the meter and your panel. When utility power fails, it starts the generator and switches the house over — usually in under 30 seconds.
Installation steps
Site survey and load calculation, permit, concrete or composite pad, gas line by a plumber, electrical wiring and transfer switch, utility inspection, startup and training. Most installs take one to two days. Read about generator installation St. Louis, Springfield and Blue Springs.
