Generator Installation FAQs
Permits, transfer switches, timelines, and what to expect on installation day.
Do I need a permit to install a standby generator in Wisconsin?
Yes. Generator installations typically require electrical and gas permits and inspections from your municipality. As a licensed electrical contractor, Southeast Electrical Services handles the permitting process as part of your installation.
What is a transfer switch and do I need one?
A transfer switch safely connects a generator to your home's electrical system and isolates it from the utility grid. Every standby generator requires one. Automatic transfer switches start your generator and switch power over within seconds of an outage, without you lifting a finger.
What do I need to do to prepare for my generator installation?
Very little. We'll confirm the generator location, fuel type, and electrical connection during your site survey. On installation day, we just need access to the installation area, your electrical panel, and your gas meter or propane tank.
How long does installation take?
Most home standby generator installations are completed in one to two days once permits are approved. We'll give you a clear timeline during your estimate.
What happens after my generator is installed?
We start up and test the generator, confirm the transfer switch operates correctly, and walk you through how your system works, including the Mobile Link™ remote monitoring app on connected models. We also recommend registering your generator with Generac to activate your warranty.
