Why would I want a whole circuit to be cut because of a single device fault

Dunno, if I have a fault in my home, I want it to be spectacular.

A couple of years ago I literally had massive blood pressure and walked like 2 km to go buy a box of fuses.

Burning two fuses, I figured out one of the extension strips was bad.

If I plug something in and half of my apartment goes black, TWICE, and needs a fuse replacement each time, maybe that thing needs to be tossed anuway. I'm no electrician, I can't troubleshoot a power strip. It has served its years. Bye.
