Input:
It actually replaced the exact same one I already had... Reason being, my portable heater/fireplace kicked on while I had my stero surrond sound unit and my big screen T.V. on all at the same time. It surged and all units shut down immediately, and the surge protector set off an alarm... Saved me about 8 grand... Highly recommend this unit.
