Flexible Conduit (N.Bundy job)

[Dustydazzler]

Nick Bundy ddoes imo a really neat rcbo board and uses some flexi conduit to get his cables across the garage which imo looks quite neat. But he gets quite a bit of stick in the comments about it...

I think there is a training issue here too. When I did my training at college there wasnt the much emphasis on the visual aesthetics of clipping and most of it was just based on "it looks passable"

It was only through watching GSH electrical videos that I realised there was methods and guidance to obtaining perfect bends/straight runs/ clipping distances evertime.

I still haven't done that much clipping work or containment but when I have I now try and spend time doing it with pride and using the guidance.

I recently clipped a 1mm HO7RNF around the outside of a friends house for some exterior lighting, spent time dressing it and ensuring clips were even and runs where straight. I went back a few weeks later to se my friend and I felt a great sense of pride. That feeling is well worth the extra Time and patience.

Correction, 93 !

Arn't there guideline's in the UK on how full a conduit can be?

Technically it was new TaE as it was a rewire job + new consumer unit

Yes there’s a conduit factor but it is based on singles. I think for other cables it’s something like 35-45% should be left as free space for circulation of heat dissipation or drawing in of other conductors but I’d have to check as it’s written in GN1 and the on site guide.

When I was an apprentice, we rewired a lot of old Victorian house in Highgate London, the VIR's on some installations were surface in a wooden type channel which you could physical see them lying in.
Trunking?

Capping and casing lots of it in Bath back when I were a Lad.

Capping and casing, you don't see much of it these days.

It was an acceptable equivalent to trunking at the time, kind of the original mini-trunking.

Did not look like it to me as the T&E was connected into the existing CU.

It also did not look as though he had left 65% of that Kopex vacant, thanks Ian for the GN1 guide which confirms that T&E is taken as the diameter of the major axis of the cable, it also mention diameter includes insulation and sheath, so seems to imply that T&E can be installed in conduit.

Well done for making up the century.
There are points worth noting in the thread......lack of teaching and training ability, for starters.
A bit more important than similar sized threads on the latest fancy dan label printers and such.

I doubt it is Kopex.

I doubt it is Kopex.

....and certainly not Anaconda Sealtite.
Used to love that stuff.....a joy to work with.

Whatever it is, the GN1 guide debunks the theory that T&E should not be used in corrugated plastic conduit.

I hate the word containment,

Containment was what the networking guy's wanted the electricians to install for their ethernet cables, that's the first time I saw or heard the term used and that was around the early to mid 80's

I do not recall that, 6months to train just saying.

Yes it was six months, I worked with a few lads that had gone through it. It produced a bit of a mixed bunch some were willing to carry on learning once on the tools and became decent sparks while others had done it to avoid losing the dole money and had little interest in the job
