Covering An Earth Conductor
Stuart
old colours) and there is no way that I can get earth sleeving on it ( unless
any of you know a way) .Is it O.K. to use tape ( green and yellow) .I presume
that's what it is made for .?

I believe that would be fine providing it's done well enough to
be regarded as permanent, and isn't going to fall off after 10
years. The purpose of the sleeving is to identify the conductor
as an earth, not to insulate it. Note that you must use a single
green and yellow tape -- mixing separate green and yellow tape
to create the same effect is specifically forbidden somewhere in
the wiring regs (green might come off, leaving yellow which looks
like a phase conductor identifier).
Of course, sleeving is available in just about any size. If you
go to an electrical wholesaler, they might well give you a few
inches for free. I have some which is large enough for 16mm T&E
somewhere.

I am sure I have some yellow and green somewhere but cant lay my hands on it so
will need to buy anothe roll. .I've looked around for larger bore sleeving but
can't see anywhere selling much above 5mm sq'd

No, sorry, tape isn't allowed for this. Reg. 543-03-02 specifically
requires the use of sleeving complying with BS 2848.

I think you're confusing area and diameter there. The largest 'earth'
that requires sleeving is 6 mm^2 (area). This has a diameter over the
seven wire strands of just over 3 mm - so readily available 4mm (i/d)
sleeving is fine.

If you do mean that then what about larger capacity cable .? You seem to be
suggesting it does not need sleeving .
The cable I am using is 10mm sq T+E and so far I haven't been able to get any
sleeving that will look anywhere near to going on this ,even warming it doesn't
help.

probably quicker to get a little tin of humbrol yellow for 50p and
paint a few lines on. Household gloss topcoat should stick very well.

Or get two lengths of sleeving and slice them each lengthways then put one
length on then glue the other on top over the opening of the first length .

No. The earth within T&E cable is (more the larger sizes) of much smaller
area than the live conductors. I can't remember the exact size of the earth
within 10mm T&E, but wouldn't fall on the floor with shock if it happened to
be 6mm.

There's a joke in there somewhere.

Good to hear the OP has solved this, but just in case others come
googling.......
Would it be permissable to untwist the earch conductor, re twist it
into two thinner "wires" sleave each of them and then connect them as
one (you could even recombine the twists at this point) into the
accessory?

No, I mean that the requirement to fit sleeving only applies to earths
that are themselves of a size up to and including 6 mm^2. All sizes of
T&E need their CPC (earth) conductor to be sleeved. The largest size of
T&E is 16 mm^2 (with 6 mm^2 CPC). In general the CPC in T&E is two
steps smaller than the L & N conductors - the only exceptions are 2.5
mm^2 which has a 1.5 mm^2 CPC and both 1.5 and 1.0 mm^2 which have 1.0
mm^2 CPCs.

I really don't understand why you're having this problem. Adequately
sized sleeving is readily available - e.g. here:
