Cables and Zones

[Des 56]

Thomas,for future refer to your regs book for how to protect a cable when its outside zone,a example would be swa,metal conduit,greater than 50mm deep
There are ways and means to overcome all you are likely to encounter on domestic work

@Des 56 Awesome advice. Thanks. Will do!

No need Thomas you seem to have all the answers you require, it's just a quirk of mine, nice to know the experience of people you are trying to help, if you wish to keep that private, then that's your prerogative, good luck

I’ve also started looking at peoples profiles before answering. If they are not allowing me to see there profile I’m not responding also.
There is a lot I’m not responding too.

In these circumstances personally I bend a bit of steel conduit to serve the outside light. This removes the need for it to be run within the zones. The conduit must, of course, be earthed.

If the conduit provides sufficient mechanical protection to protect the cable against penetration from screws or nails, it doesn’t need to be earthed.

another option would be to raise the position of the switch to the same height as the outside light.

Conduit doesn't, so your point is bizarre.

When house bashing new houses I used to take the view that if there was a light on the outside you could see it through the transverse no different to a socket in one bedroom backing on to another. the bit that I had trouble with was when a wall outside light is not where an exterior door is. Most cases I can move a double socket slightly or add an extra so that the outside light cable comes in inline with it.

Don’t know what kind of metal conduit you use?
The metal conduit I’ve used would.

Strange, because I've seen someone drill right through concealed steel conduit before and hit the singles contained within. I'm pretty sure Guidance Notes explicitly state that conduit wouldn't meet that requirement too and therefore needs to be earthed.
