A lot of things might use 4 times the rated load for a bit.

Quite; motors, filament lights, halogen lighting, transformers,
diode/cap
input PSUs such as computers, wallwarts etc, none of these things exist.

**** all of those take 4 times the rated load for any
real time at all as far as a breaker is concerned.

An office of 20 computers kept tripping the breaker where I used to
work. It was bloody annoying. They had to carefully plug each one in
seperately. It wasn't switching them on that did it, it was plugging
them in.

Which suggests they were tripping a RCD rather than a MCB?

(circuits of IT kit are well known for having high leakage currents)
