  • The fuses protect the lines upstream to the next protection device. That doesn’t mean every house could max out their breaker at the same time. Just like you can’t pull the max amperage on each circuit breaker in your panel without popping the mail breaker.

    To answer your question, most American homes I’ve seen have 240V at 200A. Some older homes have 100A.












  • I had this bad when I first got into embedded design. I built a Nixie tube clock with a Parallax SX chip in raw assembly.

    Running at 4MHz, I had to give it a nop loop where it spun for 4 million iterations just to increment the clock for a second. It lived a whole life between seconds and it would do this thanklessly tedious work forever.

    Or how about airbag sensors or seatbelt pretensioners that check sensors thousands of times a second for years in the off chance that they detect a crash and save the life of a person who they will never comprehend for the 100ms duration of a crash just to get scrapped with the rest of the vehicle.

    At one point I wanted to write a short story based on this concept. A story of unrequited love between a person and a machine that they don’t even know about.
