The reason for that is if a plug had a fuse in it and it blew during a
live performance, it was not a quick or safe job to get a maintenance
man out to climb into the suspended walkways in the dark, find the
plug, unplug it, take it apart, replace fuse, reassemble the plug,
plug it back in and vacate the suspended walkways.
Err, theatre lighting doesn't use a ring main. Most usually a radial
with dimmer control. You don't want such circuits confused with a GP
mains supply - hence different connectors.
yes, but the reason is you don't want a fuse in some remote part of the
rig.
Chicken and egg? I'm willing to bet there are some projection/effect
luminaires that do have a local fuse somewhere, though.
