The Generac 7043-2 at the house is rated 22 kW on propane and 19.5 kW on natural gas, runs on natural gas, and feeds a 100-amp transfer switch. It was installed in November of 2018 by another company.

Standby generator questions from Helmetta homeowners
Will a 22 kW generator run an entire Helmetta house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
What is a sediment trap for?
It helps stop foreign material in the gas line from reaching the generator's fuel controls. Where the fuel-gas code and the system configuration call for one, it is fitted, and the maintenance schedule includes inspecting or cleaning it.
