In another forum I read about a RVer who plugged his surge guard into the 30 amp outlet at a friend's house and spent a night without electricity (Well Shore power)...
He posted wondering what was up.. next morning he investagited
it was a Dryer/Welder/Air compressor/Other 240 volt outlet
The surge guard (TM) worked as designed and protected his rig.
now.. are they superflorus or not?
Second story (personal times about 4 so far)
Just earlier this week (and 3 times prior) power went out here in the park for like 1 second.. now,, I've seen A/C's try to re-start "Hot" they make kind of an ugly sound, then the over heat cut out kicks in or the breaker trips.
Surge guard (TM) held power off for the required nearly 3 minutes.. Time delay on the A/C (A few seconds) took care of the rest of 3 minutes.. 3 Minutes is the MINIMUM recommended "Time off" for the compressor.. All 4 times the re-start was normal.
Another factor.. Oftren when power "Blinks" like that the first few seconds are kind of wild. Major rollar coaster voltages spikes can break 1,000 volts and dips to 50 or less. This can mess you up some.
Surge Guard (TM) and Progressive Industries EMS units hold you off for way longer than it takes the rollar coaster ride to end.
So yes, they are needed, times 3 at least.
