3. Setup & Installation
Proper installation of your Generac Guardian generator is crucial for safe and efficient operation. Generac strongly recommends that your new Home Standby Generator be installed by a certified and licensed electrician or a Generac authorized dealer. This ensures compliance with all local codes and safety regulations.
3.1 Sizing Your Generator
The 24kW unit is designed for whole-house coverage, especially for homes 2501+ sq. footage. Consider your specific power needs, including air conditioning, kitchen appliances, furnace, sump pump, bathrooms, bedrooms, living areas, well pump/water heater, home office, and garage. An authorized Generac dealer can perform a free in-home assessment to determine the optimal size for your requirements.

3.2 Fuel Connection
The generator connects to your existing natural gas or liquid propane (LP) fuel supply. The 24kW rating is achieved when operating on LP gas. When operating on natural gas, the unit will provide approximately 21,000 watts due to differences in fuel properties. Ensure proper gas line installation and regulation as per local codes.
3.3 Transfer Switch
The 200 Amp SER transfer switch is installed next to your home's main electrical panel. This smart switch automatically detects power outages, signals the generator to start, and transfers your home's electrical load to the generator. Once utility power returns, it seamlessly transfers the load back and signals the generator to shut down.
