Each individual reader will have a different setup, for your sake of illustration, We'll use our home as being a template to aid you consider every one of the diverse power needs located in a standard residential setting.
It provides ample surge security. In our tests, the CP900AVR knocked down our five,000-volt surges to just 540.4 volts.
