Ring, Radial or Both

[bigd]

Guys (and girls),

Just looking for a bit of advice regarding a re-wire, which I intend to use for my Elecsa Assessment.

I've been quite fortunate that I have a friend who's allowed me to complete a full re-wire on a small 2 bedroomed house. The house has been unoccupied and he's not in a rush to get the re-wire completed, so I've been able to gets lots of advice and take my time with the re-wire.

The question I have is regarding the new extension he's having built at the back. Its going to incorporate a medium sized kitchen and a small day room. I need some advice regarding whether I should be using a ring or radial circuit for the extension.

Obviously the cooker will be on a separate circuit. But what about sockets and fused spurs (fridge, dishwasher etc)? My course instructors (yes, yes I know zero to electrician in 4 weeks) preach the gospel of radial circuits. Ring circuits are dead, radials are the future and so on.....

But it seems to me that rings are an elegant solution to my problem.

I guess I'll be installing approx 12 double sockets in the whole of the extension, plus a dishwasher, fridge/freezer, dishwasher, tumble drier

What are your views?

I like radials as they are inherently safer, I'd go for 2 radials

oh,oh here come the ring fans......

+1 for radials

I like radials but its what im used to i suppose

Ring for worktop sockets, radials through a grid switch system for aplliances

 

[BillyTheSparks]

I would wire the kitchen sockets with a ring circuit, which would incorperate a couple of appliences.
And then another ring for the other sockets and the other appliences.

Obviously, This will depend on the lay-out of the rooms etc.

I am a big fan of radials, but use rings where I feel necessary.

Like the last two posts, that's my preferred method for a kitchen installation but there is always an added cost implication with it and so it's all about your customer's budget/s too.

radials for me, easy to test

or, what abour 1 or 2 4mm radials?

I would wire the kitchen in a ring including extractor, F/F, D/W etc through a grid switch and then wire the dayroom in a radial if you want but at the end of the day its only one more cable to the box to make that a ring!

Cheers

What is this so-called instructor talking about ...''Rings are Dead''?? Just what are you being taught at these collages and training centres these day's?? Listen, ..rings perform a more than adequate purpose in small power distribution and have been doing so for a very long time!! Nothing wrong with radials, they also serve a purpose too.

This rubbish about radials are easier to test, so are better, must stem from those that are lazy or incompetent sparks. Not exactly rocket science to thoroughly test a ring is it. There's nothing inherently safer about a radial, that's been badly designed and/or installed, and the same goes for rings or any other type of circuit come to that. You design and install any circuits to suit the requirement of it's needs, Not because they are easier to test.!!!

It's not the design of a ring circuit that makes them any less safe than a radial, but the person who installs them.

small - prob radials only

large floor area a mix of rings and radials

radials are inherently safer if im not mistaken:26:

radials are safer because faults are easier to identify for the end user (ordinary persons). So in the scenario of a fault, a radial IS inherently safer.
ring finals were introduced for one reason only, and it wasn't safety.

I have never used ease of testing as a reason of choice.


just checked the video, where is the claim that its easier to test?
