  On a tangential note, is it possible to
"lean" on a typical household
 breaker to stop it from tripping?  Sort-of-like "battle override" on
 a Navy ship...  Or is the lever only good for resetting, and holding
 it will not stop it from tripping?  I think the latter but I've never
 tried it for real. 
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.
