Hello,

Please can anyone tell me the rules about junction boxes?

I could not find anything in the "old" FAQ and the wiki FAQ's rewiring
pages reports an error.

Can you use a junction box if the last bit of cable on your reel is
not long enough or should the cable be continuous? Should I save the
piece that is too short for another job and start the new reel
straight away?

Is it permissible to use junction boxes where you break into the
existing ring to add or remove sockets to/from the ring main? Or again
should you run continuous cable from socket to socket?

I used google but could only find a US FAQ that says: "Junction boxes
must be located in such a way that they're accessible later. Ie: not
buried under plaster." Is it acceptable to use them under floor boards
provided they are secured to a joist with at least 50mm from top and
bottom of the joist? Ort is under the floor considered inaccessible?
How accessible is accessible?

Thanks,
Stephen.

find anything in the 16th when I looked)
