[Guest55]

just as soon as a competing bid has been offered by the ring supporters........

Well I've got 10 then. 9 of which are arguments against your 9.

how do you know what points i'm going to make ?
no worries though , as the highest bidder i'll be happy for you to list your points first.

Get your 9 points posted biff and I'll give you my reply...

radials - pro's

1. no consideration needs to be given to balancing of loads across 2 legs

2. Quicker to test

3. Quicker to install

4. More flexible in cable layout to each point

5. Easier to add extra points at later date and with fewer restrictions with regards to where you can extend the circuit

6. Less chance of cross connections at the CU

7. Saves on cable when floors of a property dont require 32A of power , eg 2 bed terrace houses.

8. integrity of the original circuit layout is less likely to be abused or altered by homeowner /diyer.

9. Greater current capacity for the quivalent amount of cable used , eg
how have a ring main for the ground floor of a house - remove the midpoint cable and this leaves you with 2* 20amp radials - so you have a net gain of 8A for exactly no more cable.

In my house, which is over 4 floors, I have no less than seven socket circuits (mix of rings and radials), totally illogically installed, but safe nonetheless. I didn't install them by the way. I'm just thinking of rewiring at some point, and it got me thinking about how I'm going to do it. Just a bit of background as to why I started this thread!

Rings...

If you get a break in the cpc, the whole cct still has an earth; cpc break on a radial, no earth beyond that point.

also takes much less typing for a convincing argument

 

[Guest55]

well so long as no-one takes my cheeky challenge too seriously , it may serve readers to think about all the design options in even simple domestic scenarios.

 

[Guest55]

archy , your list only has 1 pro ? lol.
you can do better than that.
;-)

 

[Silly Sausage]

Not me biff.
I think it boils down to personal preference.
There is no definitive answer for either option.

That's all I need, case proven!

Can't sit on the fence any longer
Its Rings and Radials for me lol


Anyone ever installed say a 1.5mm radial for sockets and lights of each individual room ?

 

[Silly Sausage]

No. We've moved on now here in England, no 30W Pigmy bulb in each room and the wireless in the Parlour.

They'll find a way, they always do.

 

[Guest55]

case proven ?
er , ok lol.

 

[Guest55]

They'll find a way, they always do.

but its less of a problem for radials when it happens.
which is why every other day we read threads on broken ring faults ;-)
