I had a disconnected CO detector in my living room. Before working with the detector I had flicked some of the breakers off for the house, including the main breaker by accident. I tried hooking the detector up myself (the right way) and once assembled I tried flicking the main breaker back on, but it wouldn't go. When I called Emmons after hours and left a message containing my situation, I got a call back immediately from Brad and he instructed me on how to get the power back on. You have to flick ALL of the breakers off (starting with the main breaker) first. Once that's done, you can flick the main breaker back on, and then flick all of the individual breakers on. If you hear a beep once a breaker is flicked on, that's the circuit where the problem is occurring. Thanks for the help and for saving me some money Brad!
