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.
