luckily my shop is within public works building and we have a generator that runs the whole building. we have gone 3 to 4 days on the generator in the past...
A lot do. Mine happens to be in a 1963 tin building. For years I had a little portable generator that could a few things at a time. It was a major pain. We use to buy signs and it was ok for a time. But now we need the power to make signs. Most government agencies have backup generators, I know of many who don’t.
