If we’re being honest with ourselves, few (if any) home owner is ever going to go through with locking circuit breakers. Because it’s completely overkill.

In the Real World, you’ll just tell your wife/kids/roommates “Hey don’t touch the fuse panel until I’m done doing this thing” and it’s not an issue.

One of the funniest things I saw like that was my dad on a ladder in a closet trying to sort out a switch and light fixture with a voltmeter and my special needs brother repeatedly going outside and flipping off the circuit breaker. Leaving my dad cursing on a ladder in the dark.
