It is recommended that you have your Home Standby Generator System (generator and transfer switch) installed by a licensed contractor. Failure to do so could be dangerous for both family members as well as outside repair workers trying to fix downed power lines. In addition, professional installation is required to maintain the warranty. Most Briggs & Stratton Power Product dealers are capable of not only performing the necessary installation, but can also offer maintenance agreements that ensures that the generator is being serviced on a regular basis.
