So this happened at OESH this week:
We blew a fuse. Well, actually, we didn’t blow a fuse. An exuberant vine on one of our power line poles blew a fuse. It was a fuse for one of the three transformers for our 480 volt line that went kapooey. That meant all of our 480 volt machinery was down and we couldn’t injection mold for two whole days. As frustrating as it was getting further behind on orders while we waited for Dominion Power to come and fix it, I wasn’t about to try to climb up the pole to try to fix it myself. Honestly. An electrician will tell you: 110 volts can certainly kill you. 240 volts will most definitely kill you. 480 volts will kill you a few times over.
At least our 3D printers marched on through the whole ordeal. They’re only 24 volts. And can be completely unplugged when changing their cute little fuses, which hardly ever seem to blow, anyways.
