PVC trucking is NOT mechanical protection therefore any cables inside need to be double insulated and if in singles each single line conductor needs to have a cpc.

Now where have you get this from. Load of rubbish by the way

First point is having single in trunking. If it is pvc trunking then thats a NO NO for a start, unless double insulated with each line conductor having a CPC?

Was this taught on a Electrical Trainee course I wonder or do you only know of mini trunking and not of larger non metallic trunking systems ?

BGB 521.10.1
Non-sheathed cables for fixed wiring shall be enclosed in conduit, ducting or trunking....

Non-sheathed cables are permitted if the cable trunking system provides at least the degree of protection IPXXD or IP4X, and if the cover can only be removed by means of a tool or a deliberate action.

521.10.1 Non-sheathed cables (singles with no CPC btw) are permitted if the cable trunking system provides at least the degree or protection IP4X or IPXXD , or if the cover can only be removed by means of a tool or a deliberate action.


The OP has not stated the nature of the trunking within this installation that he has come across, this is why I have said if it is PVC trunking you can not have singles without and outer sheath and a CPC, AKA mini trunking which I think it will be going from his post. Cant see dado trunking running up a high wall to the lights can you? It could well be matallic trunking but if is was he should have said and if it is I'm sure by the quantity of info given he would have said something along the lines of "singles in metal trunking."

Electrical Trainee pmsl :rofl: Last job I've just finished was installing a 55m run of 185mm 4 core to an 800A DB bigger than your bed lol. Yep I need to get my head around mini trunking, just remember that you cant put singles in it as above.

I was just typing that as you posted it lol...... at least people now know not to put singles in mini trunking pmsl.

"or if the cover can only be removed by means of a tool or a deliberate action."


How would you define 'deliberate action'?

If the lid doesn't mysteriously fall off on its own accord, someone would have to 'deliberately' pull it off.

What do you class as mini trunking?

 

[KAS1]

His post did not lead me to think of mini trunking I perhaps wrongly assumed it was metal trunking with metal clad sockets !!!!!!!

 

[telectrix]

i can't see the problem with mini trunking. it performs the same function as larger stuff, but smaller.

Me neither

 

[KAS1]

I'll third that

 

[telectrix]

and it provides at least the same mechanical protection as the sheathing on T/E.

I wouldn't put that interpretation on it. If properly installed I don't see why singles in mini trunking shouldn't comply. If there are no gaps above 1mm and the covers are snapped on properly, you won't get inside without a 'deliberate action'.

 

[Pete999]

I'll 4th that lol

 

[KAS1]

I think someone is getting confused, thinking that if the trunking is non-metallic then each circuit has to have a cpc ran in following the same route of the line conducts and to achieve this they are interpreting it to mean within the same cable and also that the mini trunking is not installed correctly ie continuous, fixed and with it's lid on............ so it's not affording any protection for singles........
