I've read that too but I've also read that if the UPS never sees the |
18 |
transient spike then the UPS shouldn't react to something it never |
19 |
sees. Thing is, the UPS costs more than the surge strip does, at least |
20 |
mine does anyway. I'd much rather the surge strip burn out than it |
21 |
damage my UPS. I'd rather sacrifice the cheaper component first. |

As you point out, if it is a direct hit, or even a not so direct hit, |
24 |
nothing is going to help the UPS at that point or anything connected to |
25 |
it. Lightening is a evil and mean thing to electronics and even motors |
26 |
and such when big enough. I've seen surge protectors blown completely |
27 |
apart like someone stuck explosives in there. Sometimes, the stuff |
28 |
attached is unharmed. Sometimes it is. Depends on just how hard a hit |
29 |
it is I guess. |

I'm hoping to get me a whole house surge protector that goes in the main |
32 |
breaker box soon. They have come down in price since more companies are |
33 |
making them and there is some competition. If I use one of those, the |
34 |
UPS is going to have a surge protector in front of it anyway, whether I |
35 |
have one at the wall or not. I haven't found one but read that there is |
36 |
one that goes under the meter that works very well, if grounded real |
37 |
good. I've read they are expensive and the power company has to install |
38 |
them, since they are under the meter. |

Either way, I hope I don't get hit, at all. I don't want to even a |
41 |
little bit. Heck, I don't like the little spikes/brownouts either. We |
42 |
all know how weird that can make a computer act up. Random resets, |
43 |
memory issues, CPU issues and no telling what else. |
