I am wiring a light up in the garage and adding a double socket and
have decided to use 20mm round conduit to house the cabling.

Does anyone have any tips on feeding the cable through the conduit ? I
am using inspection bends to make a couple of 90 degree turns and the
cable is getting stuck on the corners. Even with access to the corners
by removing the covers it still seems impossible to feed the cable.

I am using 2.5mm cable for the power socket. Can you use the cable
without it's external white rubber sheath when it is inside plastic
conduit ? This would obviously give a lot more room and make feeding a
single wire at a time easier. The PVC conduit itself must surely be
performing the same if not far better job than the white sheath.

Yes, it is normal practice to use unsheathed cable inside conduits.
There are special lubricants available to make it easier to feed cable
through conduits (tallow comes to mind, is that right?).

Yes, you should be using "singles" in conduit, not twin & earth,
otherwise it's virtually impossible to feed. You can buy the individual
red, black and green/yellow cables at electrical wholesalers (I'm not
sure if the sheds sell that sort of thing). If you use your existing
cable and strip the external sheath off, you will need to get some
insulated earth conductor.

Some do, but IME a wholesaler will be cheaper.

Singles are stranded conductors which makes them easier to feed.
T&E isn't (until larger sizes).

You can get draw wires (springy metal or plastic) which easily push
through conduit and then pull the singles back.

Yes, that's true, it's still going to be awful to feed through even
without the outer sheath. Not to mention having to strip it all. Better
go out and get the real thing, it isn't expensive, though you might have
to buy a 100m drum.

Yes, it is normal practice to use unsheathed cable inside conduits.
There are special lubricants available to make it easier to feed cable
through conduits (tallow comes to mind, is that right?)

IIRC, single cable has rather thicker insulation than those used inside
TW&E.

When I started work (30 years ago) we had to feed cable thru some
plastic sheathing - we used talcum powder to ease the path, and it
worked very well Just before pushing the cables in you dust a little
talc into the opening. Could be a bit messy though.

Please don't take my word for it that talcum powder is okay for this
use though, the regs will have changed more than a little in the time.

Down in Spain, all wiring is done this way (and terrifying it is too). You
get a bit of plastic coated metal, a bit like a net curtain hanger, but 10
or 20 metres long, which goes straight through and round any corners. The
you attach the flex to the other end, and just pull it through.

If you can't get these things in the UK, I suspect that a good length of net
curtain hanger would do perfectly.

French chalk. Talc will work, but f/chalk is better.

Single is stranded and alot easier to feed, however your meant to use a fish
wire- push that through first and it has a hooked end for gripping the
cables which you then pull through. Dead easy.

Wholesaler will stock it- about a £fiver.

On a separate note, I am currently wiring up the power circuits to my
garage/workshop. I was just intending to surface mount the cables
using normal cable clips - is that OK? Or is it mandatory (or just
advisable?) to use conduit? Even up in the rafters of the garage
where most of the cables will run?

Thanks

Surface clipped wiring is OK except where it might be susceptible to
mechanical damage. In a garage/workshop wiring out of the normal
working areas can be just clipped but I think it should be protected
(mini trunking or whatever) when it runs close to benches etc.

Thick wall PVC conduit or trunking is a much better idea - gives a
reasonable degree of mechanical protection.

I have a spray of silicon lubricant ... quick spray over cables and they
slide in easy.
