Singles in conduit

Embarrasing question
Singles-does that just mean separate wires
One neutral wire one cpc wire one line enclosed in conduit
Rather than the all in one cable t&e

Yes, single insulated cables.

You can get say for instance meter tails, these are insulated and sheathed. Some people would call them double insulated however.

Yes type 6491X single core cable in to google

T&E is generally solid conductors , whereas singles are stranded and more pliable without the fear of conductor breakage when pulling around bends etc ,

Hi, Great site you have here guys. I`v being watching for a few months, and now have a question.

In colege, they have told us that when wiring in steel conduit, all wiring is done in single core cables, as opposted to Twin+earth.

Is there a reason for this?

Would seem logical to me to use Twin+earth, to keep things tidy...

Thanks in advance.

Yes Rich a sealed conduit system be it metal or PVC is an ideal way of wiring with singles, imagine wiring a lighting circuit in twin and earth in conduit, near impossible.

2008 need to be a bit careful, nearly 8 years ago last answerd

Singles for full conduit systems, RG gave an good explanation.

Didn't think mine was that bad as well lol.

Yes, except in steel conduit you wouldn't necessarily need the cpc as a cable since the conduit normally satisfies the requirement

Yes, single insulated cables.

All cables are single insulated. The sheath is mechanical protection and has no rating as insulation, even if made of insulating material.

Yes type 6491X single core cable in to google

And 6491b.

 

[DPG]

And 6421B if you want to confuse things a bit Daz

[is it appropriate to use singles for a three phase motor also in conduit then

 

[Richard Burns]

Single core single insulated cables (singles) can only be used where they are protected from damage and the insulation is not exposed to touch.

This in practice means that they must be fully enclosed and the usual methods of containment are conduit or trunking.
If this containment is maintained up to the connection to the piece of equipment then this is acceptable.

For a motor the cable may be subject to vibration and a more flexible cable may be appropriate in some circumstance, however if the vibration is limited then singles in conduit can be used for a motor connection.
