Why would anybody run around the house to unplug things during an electrical storm? How are you going to unplug the refrigerator, stove, furnace, freezer, all the most expensive items in your house? Get a whole house surge suppressor and no need to do this. I get the surge suppressor from my local utility for $6 a month. I think this is superior to the electrician installed unit in the electrical panel for a number of reasons:
1) you don’t pay for an electrician to install it
2) you don’t pay the large sum of $500-$1000 for the unit itself
3) since it’s installed behind the panel, how are you able to look at the lights to see if it’s working or not?
The suppressor installed at the outside meter is maintained by the utility, catches the surge before it enters the house, and you can check the lights very easy.
For computers, have a UPS device that gracefully shuts down the computer based on battery life.
