I live and work in the southwest, where we experience serious seasonal monsoon storms with a lot of lightning. As a result, we have to deal with power surges quite a bit, not only from the storms, but with the POCO switching around grids during the subsequent repairs.

Due to this, TVSS's are a growth market in the area, primarily for computer protection in all office situations. In studying the suppliers tech data on the various units available, I've found a hole in the available information. Perhaps one of you could fill me in;

1. What is the efficiency comparison between quality type plug-in units compared to a panel mount?

2. Which is better? A higher, or lower "clamping Voltage" rating.

3. From the data that I have read, (supplied by the manufacture's ), is it really adviseable to combine panel mount TVSS with Plug-in strip type tVSS?
