why not make all circuits radial?

[Dizzy_Maskell]

Yes I think banish the ring final circuit.
20 amp RCBO radial 1 upstairs 1down and dependant on house size a 4mm 32 Amp RCBO radial for kitchen
Job done

If you have 2 radials feeding a kitchen, ie 1 for the sockets and 1 for the appliances, you use less cable then 1 ring.

Really. Not in most kitchens I see where the appliances are fairly close to the sockets.

Yea fair point, depends on the layout of the building and kitchen itself, Its practically no difference. I'd say two radials would be better anyway tho as long as you have room on the board.

Think we are missing the fact that the modern CU is designed with the ring in mind hence why 10 way so if you were to run radials then you would need more ways ie 12-14 mcb or we go back to doubling circuits up to make room a bit like existing when the 2 light circuits are put into 1 to make room for a shower circuit

Certainly not going to read this thread from the start because the thread title content didn't make much sense to me

I understand in other countries it is the case,but we have our systems and we are expected to understand our systems

The ring and radial circuits gives us an option that they don't have

The ring and radial both have their merits and their disadvantages,use them to suit what you are installing and its happy days

An example of why not make all circuits radial would be
If we were running a lighting cable around a football field,surely it could be both cost effective and easier to install with either option.I suppose it would depend on the actual practicalities of the installation route

Nice, that means i can install a 40+ way CU in my house, and thats before i connect lighting etc, its just for the 40 sockets.

 

[oldtimer]

Another point would be the 13 amp plug top because we can fuse down funny thing is the supply that comes in from the street there is a good chance its wired in the form of a ring to help with volt drop

where did you get that bollox from ?

a 32a radial does the same job as a 32a ring but with 1 less cable in the CU.

this is one of those topics that always brings out a load of ill thought out "traditional" bullsh*t.

If you use one of these you can add all sorts of accessory switchgear such as contactors, Elight modules, timers even enough room for a few RCDs, MCBs and a couple of RCBOs

You see...lots of room - lol
and looks neat and top notch professional.....

We did a job about 5 years ago, luxury apartments in London, each one had a 12 way M Gerin TP&N DB with single phasing kit giving 36 single ways. The smaller apartments used 19 ways and the largest had 28 ways used. 3 of the circuits were also rings. I have the test sheets somewhere on a memory stick.

Yeah it does.
But it also means bigger more expensive cable is required.

And who wants to fight with 4 x 4mm T&E in a 25mm back box?

I can see that fitting in the corner of the built-in wardrobe which the builder decided was a good idea to fit after the CU was installed...

 

[Fin170]

Abandoning the perfectly functioning ring circuit and the superior design of sockets that came from it?

Na, then you'll be telling me it's a good idea to switch from Red, blue and yellow to several shades of blurr

Okay mite as well go back to 15amp round pin radial circuits!!lol
