Enclosure.

[Sharpend]

No, too obvious

Think your missing the point chaps. hypothetically a void is a big enclosure so as long as cables are fixed it shouldn't be a prob.
I just threw it in as a topic for discussion , I'm not a Electrical Trainee so don't be frightened I won't be round your patch under cutting you.:wink5:

You are misinterpreting the use of the word Enclosure in the electrical sense.

Enclosure - A part providing protection of equipment against certain external influences and in any direction providing basic protection. (As defined in the BS7671 part 2)

A void as in your OP is neither a 'part' nor is it by its nature designed to afford basic protection in all directions and/or protection from certain external influences... if this was the case you in theory could run single insulated cables down the void.

You are correct in the sense it can be called an enclosure but not in the electrical sense only in the general nature of what an enclosure is.

All you have done here is merged various definitions of what an enclosure is...

My question is - What is a plug? ....its a question you can only answer once you know the context in which i use the word as it has several answers even within our trade, mixing or merging the definitions will cause confusion if not worse..... just like the nature of this thread.

Couldn't be possible round here as i'm the cheapest, that was until we starting using plasterboard enclosures, it costs us loads in time spent making them

 

[baggy61]

Obviously not.

 

[baggy61]

Good shout.

 

[baggy61]

We save time & money by filling and sanding the joints but the plasterer says we're R.A.F. & I've never been in the forces.

416.2.1 and 526.5. Says it all really. Me, I'm off to t' pub to seek enlightenment.
Next weeks question will be on the moaning of life.
ttfn.

416.2.1.... this refers to direct contact with live parts as it clearly states in the note!........often these are exposed live parts in their normal set-up like the busbars in a busbar chamber or parts within a DB.

526.5..... This is relevant to stopping the spread of fire and a knowledge of BS 476-4 is required but if you need clarification heres the link and check out 4.5

Its worrying you seem to be misinterpreting several areas of the regs both the reg's you have quoted above have no relevance to you argument and if you read through the link 526-5 is all about making sure any joints or connection are so made within an enclosure to ensure that the risk of fire spread due to say a loose termination is kept to a minimum. I.E. - You should avoid sinking in a consumer unit into a wall where the wall provides fire protection on say 2 adjoining flats.... if alternatives are limited then the use of regulation 526.5 -iii can come into play by lining the cavity that the DB will fit into with fire retarding material like fire-board hence part of the enclosure which in this case is the consumer unit with be made up of building material complying to BS 476-4
