Does the SDSA 1175 Surge Arrester installation require turning off all of the power? Or, can the SDSA be installed while the power is on? An electrician installed one on our control panel in the garage, but power was never cut off. Just wondering if he did it right......

A surge arrestor usually has a Thermistor for inline over-current protection and a voltage clamp for over-voltage, with maybe an L/C on an up-scale unit. There is nothing that will break on a hot install. Bill Baka
