I've read that too but I've also read that if the UPS never sees the transient spike then the UPS shouldn't react to something it never sees. Thing is, the UPS costs more than the surge strip does, at least mine does anyway. I'd much rather the surge strip burn out than it 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, nothing is going to help the UPS at that point or anything connected to it. Lightening is a evil and mean thing to electronics and even motors and such when big enough. I've seen surge protectors blown completely apart like someone stuck explosives in there. Sometimes, the stuff attached is unharmed. Sometimes it is. Depends on just how hard a hit it is I guess. I'm hoping to get me a whole house surge protector that goes in the main breaker box soon. They have come down in price since more companies are making them and there is some competition. If I use one of those, the UPS is going to have a surge protector in front of it anyway, whether I have one at the wall or not. I haven't found one but read that there is one that goes under the meter that works very well, if grounded real good. I've read they are expensive and the power company has to install 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 little bit. Heck, I don't like the little spikes/brownouts either. We all know how weird that can make a computer act up. Random resets, memory issues, CPU issues and no telling what else. Dale :-) :-)
