CPC carrying live current, electrician says it is OK?

No earth sleeve is c3. Hold on I'll have a look in my book 514.1.2 514.4.4

 

I still hope M3 comes back and tells us the outcome.

Wouldn't blame him if he's too scared to

 

514.6.1 (iii) refers I guess. SO yes, sleeving is required in accessories but there are exceptions.

 

It's not something I'd class as vitally important in the grand scheme of things it's only really an identifier to point out what everyone already knows.

 

Coloumb you are correct my friend, no need for the doubt in your closing sentence and nobody is disagreeing with you. Sleeving is not insulation it is an identifier.

 

Ah yes, now I remember! Thanks

 

...and now for something completely different....

RS

 

But it is instructed that sleeving should completely cover exposed wires and that no bare wire is visible! Therefore, it acts as insulation. (In the case of bare earth wire)

Simply not the case old fruit. If it were then there would be no such things as exposed or extraneous parts.

 

'Course there would. Screws, metal parts, pipes, brackets etc

I would not consider a bare wire inside an enclosure as extraneous or exposed.

I would consider it as uninsulated.

Mr. HandyAndy - Really

 

Yes, so would I. Identified though.

 

Really, and yet I can use paint as insulation?

 

Put some rockwool insulation on it, that'll keep it nice and warm and cosy.

 

What are the insulating properties of green/yellow sleeving (or any other colour of sleeving)?

 

Its PVC, put your IR tester on it, 25mm apart, at 1000V and find out.

What we need are green and yellow 3. 5 screws

 

Is this stupid self explanatory unsafe work practicing topic still going. . .?

 

The 'competent ' have long since moved on.

 

Ah thats why im still here

 

No it isn't instructed at all. Sleeving is just an identifier and doesn't have the same properties as insulation. It is too thin and doesn't grip the conductor at all. Can I ask? Why do you insist on trying to make a case for justifying bad practice?
