Hi, I recently suffered a frozen spa. The 400 gallon unit was completely cracked apart from freezing. Insurance fully covered it, but I'd like to prevent recurrances with a freezer-type siren alarm in case power is lost. The freeze may or may not have happended from the tripped AGFI powering the spa with 220v ac single phase. We cannot tell if the tripped breaker was a result of, or the cause of the problem.
The problem is this: For the power out alarm to work, it must be connected to the 220v source. When I tap 110v off one side, and hook up a alarm device, the power draw creates an imbalance load to the non-tapped other side of the 220v AND TRIPS THE WHOLE AGFI. I thought of just using both sides (220v) and using a 220v-110v step down adaptor (like for travel). Theoretically balancing the load.....will that transformer also trip the upstream AGFI?
