Barry, can you point us to the study that says a majority of failures are due to circuit breaker/fuse deficiencies? To paraphrase someone here...
If there is such study that provides proof - not opinion - that over-current situations more often cause damage than do power surges situations, I'd appreciate it if someone could show that exact language in such a study.
That door swings both ways.
Doesn't it makes sense to protect against both types of occurrences?
