if anyone else remembers this; house fuse boxes
In the old days, there were fuses (not breakers) for your house circuits. There was a screw-in type fuse called a BUSS fuse that happened to have the same diameter as a US penny.
I can not tell you the number of houses I worked on / troubleshooting electrical issues, back in high school, that had a BLOWN fuse --- BUT behind it, was a lincoln penny!!!! When you asked the homeowner about it- the obvious answer was-- to keep the fuse from blowing! Then, when you went upstairs to check that circuit --there was a 1000 watt electrical heater, and an extension cord that had a 500 watt (tube ) radio, and in the next room, was a hot plate or toaster, etc etc etc
3-4 K watts of stuff on the circuit drawing (at start up ) 25 amps or more on a 15 amp circuit-- and the house wiring (copper in those days) never seemed to burn up.
Nowadays-- dont try this at home!
