400 Amp Service Entrance Automatic Transfer Switch for use with 30RESA, 38RCL and 48RCL generators less Load Center

The transfer switch is the brain of your Kohler home backup power system. It continuously monitors the utility power for an interruption. If utility power fails, the transfer switch automatically starts the power system, transfers the electrical loads and restores power to your home. When utility power resumes, the transfer switch reverses the process again, automatically.
