Pushing Wire Into Wall Before Tiling. HELP!

[kevg]

with electrics, if you're replacing like for like, you're entitled within the new laws to do this without having to get a qualified spark in. so if you are taking one shower unit out and putting a brand new one in exactly the same place without changing any of the wiring etc, you don't need a spark.

however, if you're ever unsure how to do anything with electrics, it always pays to get a professional in first to do the job. saves time, aggro and money later :yesnod:

Thanks for clarifying that point GRR

Unless the new unit is higher powered than the exisiting then either the fuse or cable may not be correct for the job. Get a sparks and get it checked either way.

I only ever fit 10mm T&E cable back to the board then let the sparky wire it in with the fuse he says is rated correctly.

Changing a light fitting or plug socket is one thing but a 10.5kw shower on a 4 or 6mm cable will have a melt down

Cosmo hi with regards to moving cables my interpretation would be if you have in no way changed the run and installation of the cable then it is ok, An example would be if your cable was a socket supply and was clipped to the surface and you buried it in a wall then you have changed the installation and would need it signed off by a qualified Electrician he would then have to fit RCB if not already there or mechanically protect it and test .Again if you moved a cable and it went through insulation you would need to calculate it's current carrying capacity and act accordingly.
There are jobs you can do that need notifying to Building regs and and some that do not. The british standard regs BS 7671 are non statutory but can be used in a court of law evidence to claim compliance with statutory requirements Best advice is to advise customer that you cannot touch electrical work of any kind and call in a qualified Electrician
