It may depend on the breaker. Some of our domestic RCD breakers can't
be held in, but the normal MCBs on domestic mains distribution panels
can. I used to hold in the 20A breaker on the circuit to my 19A UPS
for a second or two whenever it was switched back on, because otherwise
the switch-on surge tripped the breaker (class D breakers like we have
in machine rooms at work don't have that trip problem). Oh, and if you
don't think a 19A UPS is very big, remember it's 240VAC in the UK.
That's 4.5KW, enough to keep quite a few RA82s running.
