NVQ portfolio help - flat profile pvc cable

[Hectorhill]

I'm completing my NVQ portfolio and there's just one task I'm stuck on (so far) Was hoping someone may be able to help.

1) I need an example of an installation or use for pvc/pvc FLAT profile cable that I can write about.

Ive done commercial work mainly so something that ties into that kind of role would be ideal as I'll need to blag a picture etc. I've looked around the internet but there doesn't seem to be much about it.

any help would be really appreciated.

thanks

unbelievable!

hang on a second leesparkykent ! the portfolio has already asked for the 'everyday' pvc cables which I have happily explained.

• Thermosetting insulated cables including flexes

- Single and multicore thermoplastic (PVC) and thermosetting insulated cables
- PVC/PVC flat profile cable

Why then have they asked additionally for pvc FLAT profile cables. I cant just write sockets and lights again now can I?!

What would be the most common wiring method for a residential property?

Hector. Your wiring at home is flat PVC twin and earth. You will have it on show clipped to ceiling joists in your loft.

 

[Pete999]

Wiring houses is one example, cables used would possibly be 1.0-1.5 twin and earth for lighting, 2.5-4.0 for Ring Final circuits and Radials for socket outlets, depending on size of cooking appliances and showers 6.0 and 10.0. Usually used in what is called the first fix of a domestic new build.

Hope this is of use

I think you need to be sure of what cable type they are asking about.

Generally flat profile PVC/PVC would refer to normal twin and earth cable.

If the question is asking about specialist cabling then a flat ribbon type cable may be used for cranes or conveyors where the cable is flexed along its width but stays aligned along its length.

think that may be what they're after if he's already done T/E. also used in the automotive industry, but generally ELV.

Twin and earth. Wiring sockets in offices?.

I would like to think that domestic cables aren't being used to wire sockets in offices!

It's used every where!! It's not domestic cable. It's used in offices all over the country. What's the difference between clipping it to a brick wall in a house and clipping it to a brick wall in office.

It's ran on basket tray above false cielings and dropped down in stud walls.

The list goes on and on...

It's absolutely everywhere, can't believe the comment lol

It's not a domestic cable is it? i have used it in offices shops on cable tray, oh sorry someone else has pointed that out.

As Richard stated, think we need to be clear on the type of cable in question here.

 

[Risteard]

It's not domestic cable.

That is its intended purpose.

It's used in offices all over the country.

Because of cost - not because it is the right product.

Fault levels and a number of other factors, including reduced csa of the cpc and the limited mechanical protection afforded by it. It shouldn't be used outside of domestic installations.

I can't imagine they're expecting him to use that as part of a buildings and structures NVQ. This sounds like T&E to me - remember you have to do each module 2 or 3 times.
I think OP would do well to ask his assessor.

Fault levels?

What's the problem with reduced sized cpc?.
This is method used all over Industry

Why does it need additional mechanical protection in an office building?

What installation method would you use?

Yes it is a cost effective way. You just said you'd like to think it wasn't being used to wire offices, I was just pointing out that it's used every where.

I don't agree with you that it is a domestic cable though, it's like saying SWA is an industrial cable. A cable isnt designated to one sector, they have different properties and uses.

Just difference in opinions though...

[telectrix]

agree with that. as long as the cable is suitable for it's intended use and the environment it's installed within, then there's no rerason not to use T/E in offices etc.

 

[Risteard]

What installation method would you use?

Not least to prevent premature collapse in the event of fire, steel trunking with preferably steel conduit drops or alternatively PVC conduit drops (with galv. saddles). All wired in 6491B singles.

I must disagree that T&E is intended for use outside of domestic premises. It may well be used that way, but it certainly is not intended for that use.

I must say, that is the preferable way but numerous commercial job specifications include provision for T+E, mostly LSF.
Can't say I've ever come across a domestic property wired in low smoke....must be some, I don't doubt, but rare.

Most, if not all, higher end residential properties have specifications for LS0H cable, at least that has been my experience.
