Time to call it a day

[The Ghost]

I feel for you and know how it can be sometimes when you get sniped at. But I really cannot see throwing away thirty years after one low blow! Just update and fight back. What else can you do, shelf filling? I don't think so! Your employer has a duty to support and train anyone working for him. Why has he not assisted you, I would be asking that. Have you been sacked? No? well once more unto the breach then! or ....shelf filling.

Not sure what you mean by a 32A bracket?

However I must cringe at the very notion of T&E being used in a commercial setting - that cable is designed for domestic use only.

Say's who.?

 

[PEG]

Oh no you're not, get back here and argue about the rights and wrongs of sticking 2.5mm cable in a 32a mcb, that will go round and round and round and round and round until we all agree to disagree.

I do hope that is not a euphemism,for a personal short-coming,and a skinny bird...

 

[Risteard]

What is wrong with T&E on a commercial site or does everyone wire offices in swa now.

Doesn't have to be SWA - singles are the usual way. T&E is designed for domestic use.

 

[Risteard]

Say's who.?

The standards, for a start.

 

[Risteard]

The fact you can't use twin and earth cables in commercial installations is absolute nonsense!

I didn't say you can't. I said that you shouldn't and that they are not designed for that use.

T+E not suitable for commercial? It has been lashed in at the job I was on today - it's not always possible to have nice pretty runs of conduit/trunking everywhere to accommodate singles, and often T+E is the easiest (and best) solution.

 

[Risteard]

Exactly - T&E in a non-domestic installation is a lashup.

 

[Risteard]

In what situation is it the best solution? (Or even a good solution for that matter.)

What does that mean.? I am not up for an argument Risteard, but In my experience , I have used it, if mechanical protected ie metal trunking etc, no problem. Easy to use in commercial refurbs .

 

[hightower]

Well I'd argue that it is well suited in the environment I was in today. An old club with voids all over the place. They don't want conduit/trunking running on the surface everywhere, and it would have been impossible to install conduit/trunking in the void as a retrofit. Being able to rod T+E in the voids allows for progress to be made.

So why wouldn't you use singles in a containment system like that mentioned?

Also the cpc size is often likely to be unsuitable for the fault levels encountered in non-domestic installations.

Why not use something like Hi-Tuff then with the same csa (and insulated) cpc as the live conductors. I presume you have allowed for non-combustible supports for the wiring system and tried to prevent acrid smoke in escape routes?

Simply because it was not a full containment system. Using voids in ceiling, and stud work.

I have never read so much twaddle in all my life. Fault levels in commercial are often similar to domestic with the same type of circuit protection. What Standards do you refer to, give us some numbers.
