Hi all,
I am doing some wiring outside to put some sockets for my outdoor
kitchen. The cable will be channeled into a wall and rendered over and
then there will be a short exposed section (behind a wall) and then into
a cupboard. I have some multi strand rubber cable (HO7RN-F) which I
believe is suitable for use outside so was wondering if using this would
be ok - ideally within regs. I didn't see why being multi strand Vs
single core really matters?
Many thanks in advance

Nothing stopping you using it if it is of adequate conductor CSA for the >application in question.

Would I be right in assuming that the single core stuff is intended
for fixed instalations where the routing will not often be distrubed,
if ever, whereas the multi-strand (flex) is more for appliances which
need to be moved around on a regular basis? That would seem to make
sense to me. Flex tends to cost more than single core but the current handling of both (if sized correctly) is the same as will be the
insulation if it's specified for mains voltages. So if the OP's got
his flexible stuff for free, he's good to go I guess.

Power wiring used to be stranded, though not many strands. Ring mains
used 7/.029, which is roughly equivalent to 2.5mm^2, with lighting
normally 3/.029.

In general, yes. For larger CSA cables even the fixed wiring cable is stranded (although fewer heavier strands) to keep it workable.

Is there a big difference for, say 10mm2 T&E?
I'm about to put in place the wiring for a shower and it's quite a tortuous route. I'd bought single strand as it's fixed, but could easily swap it over for stranded if it's going to be significantly easier to thread.

I confess to not seeing single strand 10mm2 cable, I've only seen cable
of that size with what must be 7 strands!
Having to pull the cable through voids and spaces might become a little difficult!

Much depends on what you are doing with it - the main difference is
getting it into and out of enclosures and switches.
For a shower, the shower end and the CU end are usually not too bad, the ceiling switch can be a pig though :-)

Not kidding. I've replaced both the ceiling switch, and the shower in
this house three times over the years.
Wiring for the showers wasn't a problem. Those ceiling switches were a different matter altogether.
