Running cables through boxes

My colleague asked me to ask this question as we almost came to blows over it... he was apparently taught you can't run a cable THROUGH a box it doesn't terminate in... (imagine a row of sockets on an RFC... his method would have you cutting the cables at each box and jointing them?)  I... failed to see the logic and said rude words about the person who taught him. Has anyone else ever heard of this?


The argument given was that you couldn't remove an intermediate box if there was a cable running through it, but how often does a circuit need modification, and even if it does, the person removing the box should be capable of jointing the cable, or, as there'd be remedial making good to be done, replace the severed length of cable? (we're talking buried in walls in tubing or capping, house badger style, not proper surface conduit work, where he agreed that no cutting would be necessary as you can unthread and rethread the cables)

  • A long no.6 wood screw is very useful if the threaded lug in a metal back box has stripped. Also a very long no.6 wood screw can be used to hold one side of an accessory if a threaded lug has been lost or badly damaged. Just drill through the metal back box in line with the accessory fixing screw hole, and plug the hole with a plastic wall plug. The long no.6 screw can then fit through the accessory hole and be secured into the wall plug. An earth linking wire may be needed from the metal box earth terminal to the accessory earth terminal.
