      The PowerBack is intended to be installed on a manual transfer panel or generator-ready load center. During a power outage, when the main breaker has been turned off to allow the generator to provide emergency power to the panel, the PowerBack can be activated and will emit a pulsing 105dB alarm when the power outage ends and utility power is again available. The PowerBack installs in a 1/2 trade size knockout in the panel within 20 in. of one of the utility hot legs. It includes an eight-inch current sensing antennae at the end of a 22 in. jacked lead. When wrapped around one of the hot legs to the main circuit breaker, the antennae will detect the returning utility current and activate the sonic alert.

      • Works as advertised!
      • June 18, 2013

      Unit works great. Wrap around hot leg with electrical tape. This gives a tight fit. Sonalert is loud and I can hear it well at all locations. Added benefit is a magnet is on the back of the unit so you can place it on the box if the box is recessed. Good pricepoint as well.

      Pros Easy to Use, Great Sound Quality, Loud, Compact, Clear Instructions, Nice Design, Easy Installation
