Feeding cables in 20mm round conduit
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. Andy. |

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. -- Tim Mitchell |

If you use your existing cable and strip the external sheath off, you will need to get some insulated earth conductor. 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. -- Andrew Gabriel |

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. -- Tim Mitchell |

IIRC, single cable has rather thicker insulation than those used inside TW&E. -- *Eagles may soar, but weasels don't get sucked into jet engines * Dave Plowman London SW 12 RIP Acorn |

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.

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. Tim.. Tim.. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

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? 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. -- Chris Green ) |

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