capping cables

[RogertheBodger]

no, but' i'm working on a design for horse shoes with built in RCDs.

Good idea, let me know when you try it out, a few Milliamps might make em run a bit faster.

i did think of screwing zebedees into the shoes, be good for over the sticks races.

If you could get the RCD to trip when they're approaching the fence?
That would get them over OK

Shame,
Thought we were on to a winner there.

We cap all our cables, it's definitely peace of mind like people have said about protection from plasterers etc.

Also, my NVQ man said the main reason for capping is in fact to give the cables a bit of air for heat loss... I never knew that.

I think your NVQ man made that up Colin - you get better heat dissapation if the cable is buried directly in the plaster!

Having said that I like to use plastic conduit with adaptors into the boxes - slight higher cost but I've been more than happy on occasions when cables been damaged by other trades (or even the apprentice).

Sometimes certain things aren't in the regs but then surely it depends on the client specification, if your doing a rewire or new build and you don't have to have capping because its in safe zones or on a rcd but the client requests mechanical protection to be installed then surely that it was you do.

malcomsanford: I never stated that metallic conduit is never used on domestic dwellings I was simply pointing out that telectrix had missed my point entirely about using earthed metallic capping for added protection of cables buried in plaster and deemed to be at a greater risk than other cable routes. I also mentioned my experience because it helps to know with whom you are talking to in respects to technical knowledge or lack of it, and just because you have never seen metallic capping being used doesn't mean that it's wrong or going over the top to use it. If the electrician wiring a household is happy that the buried cables are under no danger and that the rcd will always provide protection then that is for that electrician to make the call, I'm only pointing out what is seen by many in the trade as good working practise, that's all.

Ken I do always do a quick test on 1st fix, but unfortunately even if you've done the tests and can prove it, the plasterer won't own up to it, it'll be 'oh the chippy was over here doing something' and then the chippy will say 'nah it wasn't me, it was the plumber.' It'll still be muggins who has to sort it out! Anyhow, I just like using oval I find it a lot easier than capping or just clipping - it doesn't bend out of shape and does exactly what you tell it to....
