Trunking in Floor Chase

[phil_davison]

Alright,

Just a quickie, I'm currently doing an install in which involves chasing a concrete floor to run the cable for the ring main.
The chase is less than 50mm and will be rcd protected as well as being run in trunking. Can I run PVC trunking instead of metal trunking as the client is trying to keep the costs down?

Cheers

I'd be worried about it's strength.

 

[phil_davison]

Thats what my concern is.

 

[benji]

why not use conduit ?

Or can you not run things above the ceiling and drop down, and run horizontally between accessories?

 

[phil_davison]

Cant run anything above the ceiling as its woodern beams london. I'd designed it all around metal trunking but, client is now asking me to try and save a few quid.

 

[londonlec]

To be honest I wouldnt be too keen even on using steel trunking. Or where you planning on screeding over the top?

I see the plumbers use a plastic duct which has a wooden cover. Maybe an option?

As Benji said, why not pvc conduit - that's what we do around my way?

its got to be steal conduit if not in a cable zone or swa

silly question was'nt it ;-)

 

[londonlec]

Do you have a reg number please?

 

[phil_davison]

I've checked on-site guide and BS7671 and couldnt find anything mentioning safe zones in floors. Hence why I've asked the question.

there are not safe zones in floors , nor did i say there were, i said unless in safe zones it would need protection

regs number ? book in van , but roughly 522.66 ish i think
