Ground Floor Sockets

[JAmmmmm]

Hey Guys, when rewiring is it better to run the ring circuit cables for the ground floor under the floorboards or to take them up the wall in piping under the plaster and run them about in the ceiling? This is assuming that there is going to be re plastering... Thinking only having to take one floor up and no wires underneath where mice ext can nibble :0 But then you have people nailing drilling pictures ext... What you think? This is in theory BTW.

It's what ever works best, providing the cables are run in the permitted safe zones.
But personally I would run the downstairs socket circuit below the floor up to the outlets. If there is a potential problem with rodents, you could run the cables in conduit under the floor.

I think people shouldn't nail or drill anywhere above, below or to the side of accessories, or within 150mm of the ceiling, or within 150mm of internal corners.

Take the route that uses the least amount of cable, which gives a lower resistance and a better disconnection time

... which are the "safe zones" spacified within the regs - but on the few occasions when I've been called out to rectify nails through cables, it's as if the householders had carefully measured up to see where the cables would be behind the plaster, and whacked the nails in!!

Often find cables straying across walls where they shouldn't be (especially in kitchen refits) but can't recall a job where someone had hit a wire that shouldn't have been there. Which is probably the signal fot eh phone to ring ....

The problem is that your normal everyday householder, does not have a clue where permitted safe zones are, and will not take in to consideration where accessories are located in respect of the cable routes.

"Remember that the safe permitted distance to run cables through joist in the floor and ceiling void, is a minimum of 50mm from both floor and ceiling"

And you should ignore that advice as well.

why?

Re #3 - what about sockets and switches on the walls orthogonal to the run of the boards?

holmslaw, I agree with the common sense/practical method that you explained.
But my reply was prompted by

I would be under floorboards passing cable through joists, at 50mm below floor depth.

That is why I offered the additional info, when routing cables through joists!
