Reliance Controls - PowerBACK Utility Power Return Alert - Unbox - Install

Reliance Controls - PowerBACK - Utility Power Return Alert - Model THP108
The PowerBACK Is intended to be installed on any 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 100dB alarm when the power outage ends and utility power is again available. This device is perfect for situations where there is no easy way to detect that utility power is restored, such as when your main breaker is turned off when on generator power.
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.
