RTS Transfer Switches monitor incoming utility power and determine when a true power outage is occurring, automatically switching from utility power to emergency generator power and back again when utility power returns. RTS Automatic Transfer Switch for standby generators allows you to safely connect your standby generator to your home’s electrical circuits. Using Honeywell's RTS Transfer Switches you can choose to cover every circuit all the time or only cover essential circuits depending upon the generator with which it is paired with. RTS open transition transfer switches are ideal for residential, commercial and light industrial applications.
