Easy To Install Device
After hooking up a new transfer switch and running a power line to the generator's home, I figured it would top off my efforts to install a utility power return alert. I searched over Google and the THP108 is the only thing I could find that meets my needs.

Well, it is perfect in that it is just what I was thinking of. Interestingly, it has a pending patent. Anyway, installing it took all of 10 minutes and it works great. It may not be loud enough to wake me up since it is in the basement,... more

It Really Works
During a bad storm we decided to test the alarm when our lights went out for a short period to see if it worked. It became late in the evening so we went to bed and when the electric came back on in a short time afterward the alram sounded. The alarm was loud enough to hear that indicated to us the electricity was back on.
Pros: Easy To Use, Price, Fast, Reliable

Somewhat Disappointed
I recently installed a Briggs & Straton 8KW generator for emergency back-up during power outages. I also installed the Reliance 30 amp watt meter MB75 to monitor the watt load. I was pleased with with the meter except for the very short pick-up leads( only about 12 inches long) much too short to reach my generator leads. I had to splice an additional 12 inches into all 4 leads. The meter was not cheap. I don't understand why the leads were so short. I also installed the Reliance PowerBack... more
