RE: [APD] IceCap ballasts hype or not?
That's the best advice yet if you live in zap town. MOVs
are what's known in the trade as sacrifical parts -- his is
because the sacrificy themselves in the performance of
their duties. Unfortunately, they also sacrifice your
equipment once they've sacrificed themselves.
There are some surge protectors that work by blocking the
surge (or most of the surge) rather than sending it to
ground or shorting it between hot and neutral -- these have
no sacrifical parts and are used sometimes in critical
applications like hospitals. Yet, the whole house method
is probably the most economical way to address the problem
