Typically surge protectors have a little light to let you know if the surge circuitry is still good. Others will fail safe, meaning the won't power on if the circuitry is bad. Cheap ones may do neither. Either way, if your house has had a surge and other equipment has died that wasn't surge protected, probably a good time to replace all surge protectors in the house, they're not really meant to survive multiple large surges. They shunt the power destructively, just somewhere you don't care. |

Is this a concern when buying used rackmount power conditioners (like used for live music setups?), to protect home IT gear? Can they be worn out without a sign that they are?
