So I was able to make the experience before short if such a device is useful or nicht.Bei us was a slight storm, which was almost taken off as again a murderous blow gab.Im house was on a (three) circuits the main fuse out and everything was plugged into electrical outlets and no extra protection had (lamps, radio) was kaputt.Auch our heating was on this circuit, but we had times rebuilt (now with power outlets, no longer firmly connected) and those with just Over voltage secured. The end was that protection was kommplett destroyed, but our heating has remained undamaged (would otherwise ca.2000, - have been damage). I can only everyone guessing about those devices or other overvoltage protection, although some are now saying, "But I am assured," the running around after his money has one anyway and a quantity of insurance carrying such one or other damage is then also the question, because the policy is terminated faster than you think, and then find a new time.
