Just following up as I'm still not fully metric, I tend to use 45mm boxes
for cookers - I hate having to cram in wires.

I've noticed when fixing 'pro' installations that many sparks cut the
tails so short it's difficult to get at the screws without standing on
your head, and that the fault I've been fixing was due to a loose
connection. And with short tails if the wire is damaged as it often is,
it's a bigger repair job.
