Technology Research Surge Guard Automatic Transfer Switch

The Technology Research Surge Guard Automatic Transfer Switch manages power between two sources in an RV. It switches between campground shore power and an onboard generator, so the two sources are never connected at the same time. It works as an RV transfer switch, an automatic generator transfer switch and a shore/generator power switch.

Key Features:

• Switches automatically between shore power and generator power when energized
• Proprietary electrical interlocking keeps both power sources from feeding the system at once
• Time delay at power up. Generator power transfers after about 30 seconds and shore power after about 3-4 seconds
• Generator dominant. If both sources are available, generator power takes priority after the delay
• Contactor-based design for dependable switching
• Hardwired installation

The Surge Guard line comes from Technology Research, a maker of RV power protection products. The switch removes the need to change power sources by hand when you start or stop a generator at the campsite. It helps protect RV appliances and electrical systems from damage caused by two power sources being connected together.
