Learned something new yesterday, the fixit guy at work explained about power strips and surge protectors. The surge protector will work, until it doesn't. No way to know when it has failed, until yo...
Far more damage is caused by low voltage (brown outs) than by surge.
BTW anyone who wants to prevent brown outs should consider the new Hughes autoformer which does test polarity, bad neutral, bad ground has limited surge capability, and of course corrects low voltage.
