Many theories - all wrong. The socket failed because of an unstuck 
screw. Everything was wired correctly, the whole circuit was on a 10A 
fuse. After many years of use (and neglect) one of the screws became 
dislodged (thermal expansion of the wires or whatever) - enough to spark 
and cause problems.
