Surge protector installation

[havin_aball@yahoo.com]

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.
