Replacing Generac gasoline generator with propane

The Generac is not automatic and has a seperate transfer panel. What rewiring has to be done if I convert to propane? Had no problem installing the Generac. FOR an automatic standby propane generator, what will have to be done? Thank you? Frank

A little vague there.

It looks like you're buying a propane generator. If it's larger than what you have you'll need to increase the wire size. You'll need to install an automatic transfer panel that will control the generator.

Since it will be automatic and can transfer when you aren't there..... you'll need to do a load calculation to see if the generator can run the load or you'll need to use load shedding relays.

For example.... if you have central air..... it is a large starting load.... if you aren't home and it transfers to the A/C it could trip its breaker. Same thing with an electric water heater or any other large load that could be running unattended.

Transferring from gas to Propane should not have any effect on the electrical side except for the fact that the propane MAYBE a little less efficient or at least NG is if switched from diesel.

How about telling us specifically what propane generator you are buying. If, as you say automatic standby, you will need to rewire for an automatic transfer switch. Depending on the generator size and your electrical needs there are multiple choices that cannot be answered without more information.
