A .22 caliber slug would almost fit actually. Just a little bit too big. Still, not sure I would use one even in a pinch.
When I was a kid I remember people putting pennies in their fuse boxes- back in the day when homes had fuse boxes with screw in fuses. You know, when pennies were still made of copper. What I always wondered was who was stupid enough to push that penny into the socket with their finger. Sure, its all good as long as you are not touching ground with the other hand.
I have hunkered down for the hurricane. System is shut down cold and unplugged. Expect heavy rain, flooding and high winds so no fuse related listening tests today. Sending this now before we lose power.
