can any one help

i am a apreentice and i was working with a non qualifeild sparky and he was trying to convince me that theres no problem in wiring lights in rings. so the lighting circiut in a ring !!!!! to me this is wrong so i aruged and refused to do it. am i in the right . is it safe to do that ?????? many thanks ryan

IT's wrong.

I've never done it.... Never seen it..

I'm not sure of a reg relating to this with out getting the books out and I'm sure there's an argument about it's safe for sockets etc

What size cable are you using? Bellwire?

Are you sure it's a ring and not a radial from one rose to the next? It does go back to the CU in a ring?

Hi Ryan,
I never thought of doing it this way as it depends on how many lights are going to run off a 6A breaker ( for example)and also what size cable is being used etc.
You dont want to overload the circuit with lights as then you have to calculate loads and cable sizes and circuit breaker ratings.
Also if say there is a problem and the circuit trips, then there is no lights at all,

I would certainly not do it this way
If I am wrong anyone, please correct me .
Regards,
Sav

I've done a bit of research and another forum has debated this and they say technically it's ok.
Although I stand by the argument of it's not normal practise

i am a apreentice and i was working with a non qualifeild sparky

Have you sort advice from your college lecture, and how can you do an apprenticeship with a non qualified spark?

What are you teaching him??????
I don't know how the college allows it, or the government.

that was my arguement so i wired it in radials and it was a office block and he was so determed but i wudnt let him. i argued that to put lights in a ring was wrong any way and that the cable size would have to be doubled. and i was using 1.5 twin. i just wanted to prove a point that it was wrong

i was working with a sparks awell and he supported me on this arguement but the non sparkys was so sure he was right. but he was WRONG lol. cheers for clearing this up .

Technically its O.K. but there really is no point unless your wiring loads of marshalling boxes even then I'd rather use a larger cable

I hate rings
We are the only country where they are legal, In france for example there is a radial for everything, 2 light on the balcony - radial, sockets in the hall - radial, so if a problem then you only lose part of an area
makes fault finding easier too as the are covered by circuit is smaller.
C/U's are massive tho, my parents have a 3 storey detatched, the board is 42 ways, took the cover off and its a really neat job, red's for live and blue for neutral (thought we changed colours for harmonisation ) but there we go!!!
the main supply cutout is digital and the new stuff seems much more modern than what we have in this country
in fact when you look at some of the older stuff here - porcelain fuse carriers and wiring like a rats nest some of it beggers belief !!!!!

I dont feel it's wrong or dangerous.....just not the done thing and to me is a pointles exercise. We only wire socket outlets in 2.5mm rings due to the copper shortages after the war and the introduction of a 3 bar electric fire needing a larger OCPD on a smaller cable.

In principal it's the same as a socket outlet ring circuit but I dont feel you could you could use a higher OCPD than the max CCC of the cable as you can in a socket ring due to the variety of lamps and fittings available (3 spot tracks, multilamp chandeliers etc) available these days, with socket outlets being limited to 2 x 13A outlets per point.

only ever seen it once was a bit of a DIY BODGE job though

dont see why you would do it though doesnt make sense to me

Lets have a short circuit past the connection into the mains, I was taught that if a short occurs in the lighting, if its off the mains 32 amps could flow, which down possibly one mil wire, would be a disaster.
If I have to do this its 2.5 from the ring, to a 5 amp fused spur, then on to the lights. Just corrected a 30 room hotel where this was in every bathroom.
