Generator Installation Festus — FAQs

What size generator do I need for my Festus home?

We run a load calculation on your panel to size it. Most Festus homes land between 14kW and 26kW for whole-house coverage; smaller units cover essentials only.

Do you install Generac generators in Festus?

Yes — Generac, Kohler, Cummins and Briggs & Stratton. We install the unit, transfer switch, pad and wiring and coordinate the gas connection.

How long does a standby generator installation take?

Most installs are completed in one to two days once the unit and permit are ready.

Can a transfer switch be added to my existing panel?

Usually yes. We install an automatic transfer switch between the meter and your panel so the switch-over happens in seconds.
