I'm replacing old rubber lights cables with new grey ones,
stringing them over the plasterboard ceiling where they used to be.

And in the attic I'm laying them along the floor where the old ones were.

But looking at my Yellow On Site Guide page 69 Table 7.1.(ii)
(Installation reference method)
I can't find these methods.
http://www.ebay.co.uk/bhp/on-site-guide-bs7671

Or is it B (Enclosed in conduit or trunking on a wall etc?

Or to pass a Part P inspection 17 or 17A3
do all or some of them have to be clipped to the joists?


thanks

I cannot see anything wrong with cables laid on top of a plasterboard
ceiling.

Cover them with insulation and its reference method 100 or 101
(depending on how much insulation you use)

just on the bottom and nothing atop the timbers, then it's fine to lay the
wires atop the timbers since there's no normal or expected avenue for wire
damage. However, Inspectors usually want to see them stapled sparingly to
avoid sag or movement into a hazardous situation and that they can't be
accidentally pulled from fixtures.

Table 4A2 in the full regs has a specific entry for single-core or multi
core cable in a ceiling void, or in a suspended ceiling. Its says treat
as method B (i.e. as in conduit on a wall)

Not when supported on the ceiling etc.

Do you have experience in the UK under UK rules & regs?

Or is this just you googling? if so why not include a link to
your source(s) so OPs can see for themselves?

Which inspectors would this be? How can a cable sag when laid across a
ceiling? How does a cable get pulled from a fixture when between a floor
and ceiling? Have you any experience of the mechanical strength of TW&E?
To do any damage would require the force of an idiot.

Clearly not as half of what he said is not correct.

Oh Indeed.

I am merely mildly intrigued by the apparent persistence of all
the "advice" even when it's plainly & obviously either somewhat
lacking or so bloody obvious as to almost be a ****
take.

(Putting aside the insistence on using the homo-owners.club
portal & the bitchy retorts to those who point out the many
gaffes...)

Still all entertainment I spose :-)

LOL

Nor can hosepipe. When my car got bogged down in soft ground when I was
visiting a client the other year, he fetched a neighbour and his 4x4 to pull
me out. My tow-rope, fastened around the neighbour's towing hitch and the
towing eye that I screwed into the towing point on my car, was not very long
and we decided that once he got my car going, it may shoot back into his
vehicle. So we needed a longer piece of rope. And my client produced a
length of soft plastic hosepipe and asked if that would do to lengthen the
tow-rope. I'm sure he was being 100% serious, rather than facetious. I'll
never forget the eyes-skywards, some-mothers-do-have-them look that the
neighbour gave me. :-)
