Do you leave your welder, grinder, drill press, lathe, mill, etc.
plugged in all the time?

We had a lightning strike. Luckily, it hit the house instead of my new
shop! It blew everything EXCEPT light bulbs. Some things were
turned on but most were not. That indicates to me that there was a lot
of arcing across switch contacts.

So, how great is the danger of burning some shop equipment? Has it
happened to you? Or even one of Steve B's mythical friends?
