spuring if a ring

[nicsin02]

Having a debate regarding spurs from a ring circuit, my lecturer at my 2391 course a few year back claimed that it was ok to have 1 spur per socket in a ring circuit, I know it ain't good practise but I can't find anything in regs book to confirm or deny point, any help much appreciated, cheers

but supposing you fitted a 20A MCB supplying the RFC instead of a 32A?

Then the rules would still be the same if you wanted it to be a ring circuit. However you could safely take spurs wherever you like but it would no longer be a ring circuit, just a Bodged up radial

yeah but only a complete moron would chose to use a ring over a radial..........

*gets popcorn and watches carnage ensue.

no, it would be a ring with spurs. the difference being that the single 2.5mm of the spurs would be protected ( In<Iz ), so what regulation/s would be breached?

Im going to ask which one as I am a total noob

 

[Guest55]

noob alert !!

xD

its all about ensuring the load is spread evenly though out the ring without excessive current applied to any 1 connection point is my take on the guidance

U guys have totally got this wrong, I was having a debate at work and I said u can spur off each point ( remembering what the lecturer had said) but I couldn't find it in the regs book to back me up.... :-/

Think someone has already said APPENDIX 15, BS 7671

So does my boyfriend!

Johnny Cash had a ring of fire

Nothing wrong with a spur off a socket, you could have a fused connection point connected to a ring main and have several sockets connected to that as well if you like :smilewinkgrin:

Now there's an idea for your shed supply!

No regulation would be breached, but it would not comply with the requirements of a ring final circuit, but it also wouldn't have to comply with the requirements of a ring final circuit.

that sounds like an answer a politician would give. :ack2:

You're all wrong!

Appendix 15 is only 'Informative'.
Which implies you could wire an RFC and spur off it, in any way you want.
The diagrams are preferable ways of wiring an RFC to ensure it complies with 433.1
