Its best done automatically with some electronics, but it is also

Not going to happen, most people are so used to just plugging
anything in anywhere and it working they get very confused if the
circuit trips.

It depends on the situation. If the person that trips the feed is suitably punished they learn. I dont mean by sitting on the naughty step, but by the results of their actions. It works in the eastern bloc with flats on 8A feeds, overload it and you're inconvenienced.


Was in the Dr's Surgery a while back and the power
tripped, came back then tripped again, rinse an repeat a few times.
Turns out the gas heating had packed in so they had half a dozen
electric heaters on...
Or take the example of the urn and kettle (ordinary not rapid boil)
to provide tea and coffee on outside broadcasts. The urn takes to
long first thing, even with a minimal amount of water in it. So the
kettle and urn are used at the same time, this is fine on a 16 A feed
from the generator but occasionally the feed is a 13 A plugtop. That
13 A fuse lasts about 5 mins if that. The number of my supposedly
"technical" colleagues who just can't understand this is rather
depressing.

Putting a number on each plug makes it elementary. But if you're dealing with employees they too often couldnt care.
