Generator Installation · Missouri
A generator must connect through a transfer switch or an approved interlock so it can never feed power back into utility lines. Electricians install standby generators, portable generator inlets with interlocks, and the transfer equipment for both.
Kansas City and St. Louis have large pre-1950 housing stocks; spring storms add surge and outage calls.
Across the Midwest, homes deal with cold winters, severe thunderstorms and tornado season. Permit offices, utilities and housing stock differ by city, which affects how generator installation is planned and scheduled. These local guides cover the Missouri cities where we have written specific notes.
Ice storms and severe thunderstorms bring outages to the Kansas City area, and winter outages are a particular concern because furnaces need power. A generator inlet with an interlock lets a portable generator run the furnace, sump pump and refrigerator safely.
Utility: Evergy
The July 2006 storms that cut power to hundreds of thousands of Ameren customers in the St. Louis region during a heat wave made backup power a priority for many families, particularly those with older relatives or medical equipment. In the city's dense neighborhoods, generators have to sit outdoors with clearance from windows, which on narrow lots often means the back yard or an alley-side pad.
Utility: Ameren Missouri
1. Size the load
Circuits that must stay powered are listed and the generator sized.
2. Choose the connection
Inlet and interlock, manual transfer switch or automatic transfer switch.
3. Install and inspect
Permitted installation, gas connection by a licensed fitter where needed, and inspection.
Electricians set their own prices; local permit fees and utility requirements add to these factors.
Permits come from the city or county where the home is. For example: Kansas City: Electrical permits in Kansas City, Missouri, come from the City Planning and Development Department; suburbs on both sides of the state line run their own building departments. Saint Louis: Inside the city, electrical permits come from the City of St. Louis Building Division; St. Louis County and its municipalities issue their own.
Kansas City: Evergy. Saint Louis: Ameren Missouri.
Listed interlock kits are accepted in many jurisdictions when installed with a permit. Your electrician will know the local rule.
