Time to call it a day

[westward10]

I shall take the challenge . I haven't got the BYB with me so I cant give you the exact page but if you take a look at appendix 15, reg 433.1.5, fig 15A and read under the 'unfused spur' title it will say:

"An unfused spur may be
connected to the origin of the
circuit in the distribution board."

If you think about it, it's exactly the same as spurring of a ring. As Ian has said, it cant be overloaded as the CCC is 27A clipped direct and fault protection is easily met with a 32A MCB. Plus.... It is in the regs as above.

Why would you install a radial, not a spur from a ring final in the same manner. Pointless exercise.

Your original post didn't mention spurs.You said you could run a double or single socket directly off a 2.5 fed from a 32amp breaker.in that specific case i would say thats unacceptable.If you were wiring the socket from scratch you would fit a 16amp breaker to feed the double or single socket.

Come on Bob, admit defeat like a man
What else is a spur if it's not fed from a 32a MCB feeding a single or double socket?
Go on Bob, I've been wrong a hundred times and am happy to put my hands up when defeated... It feels good!

 

[HappyHippyDad]

I said the same or very similar in post #13 HHD, in your defence.

Sorry Dave, didn't see that! Thankyou

I'm off to see a very pretty new girlfriend now so shall say goodbye for now.

Well it isn't a spur, it is a radial there is no ring final.

Lucky man ! I'll settle for watching Liverpool v Leicester on the telly tonight, I think the wife would kill me if I went to visit a very pretty new girlfriend.

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 would prefer LSZH twin and earth in a commercial environment of standard PVC twin and earth.

She's not new, he's had her for ages and that's why he was quiet the latter part of last year. How do you spell oooeeeooo @Pete999 is good at spelling noises!

@Sparkhe, don't be down. You have 30 years of experience to give. If you need to catch up since the 16th then hang around on here and read through the archives. There is the 17th 2382-15 from city and guilds that you would ace then you'd be back on track.
You've probably forgotten more than half of us know, although listening to us bickering about 2.5 Spurs will probably make you want to leave the game anyway.
Hoping to hear more from you, get involved and have a banter!
Respect, Rob

What sort of mood are you in for me to spell a noise for you mate? Who ever is thinking of giving up,don't or I'll come over and smack you one understand?

 

[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.?

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.

 

[hightower]

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]

It has been lashed in at the job I was on today

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

 

[Risteard]

often T+E is the easiest (and best) solution.

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

 

[7029 dave]

The standards, for a start.

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 .
