Bring it on...death of the ring cant come quick enough.....(note....spent 3/4 of a day today trying to find a break in ring continuity on the lives of a ring....PLASTERED IN JOINT in a flush box with cardboard cover...connectors....obviously wouldnt of happened if he'd used wago's)

Another job done and tested all good readings!! Had to change two faceplates on down radial as wasn't getting my r1+r2 readings

How did changing the faceplates help your R1+R2 mate?....dodgy switches?

sockets in property approx 20years old, they give false r1+r2 readings, so i just change them first reading 1.42ohms second reading 0.22ohms !! more like it!

only some if any do it???

Bad contacts on the pins then....not done bad to last 20 yrs though!

 

[domestic spark]

am i correct in saying thee isnt really a max r1+r2 reading you can obtain??

They thought of this a while back when trying to get rid of our 13amp sockets & using 16amp sockets. Other countries dont have ring mains. I have wired kitchens on 4mm2 or 6mm2 radials, saves worrying about any overloading when you'r not sure of appliances. I rewired my bungalow & have no ring mains. 20amp radial to bedrooms, 2 x 20amp radials to lounge & dining room & 2 x 4mm2 radials to kitchen = 6mm2 for cooker, regards piccollo

if you dont know loads, what is the max amount of sockets you can have on a radial??

as ring is unlimited within 100m 2 right?

Unlimited sockets on a radial but max floor area of 50m2 for 2.5 T&E 20A radial or 75m2 for 4.0 T&E 32A radial.

Good grief how do you get 2 6mm^ in a BS 1362 socket, 4mm^ is pig enough

I've never figured out the reason for the British love affair with ring circuits. Surely radials have many advantages....?

Last 2 Victorian terraces I rewired were both 3 storeys with cellar.

Nightmare getting rings up the old studs so 4mm radial power for each floor.

I am using radial power more and more, better future proofing for DIY idiot!

It is just the case of old habits mate. It was invented just after the war as folk lore tell for when copper was in short supply. I was brought up on ring final circuits but have to admit I personally prefer radials purely from the testing and fault finding side of things.

Like all things I suppose it is a matter of picking the best design for a particular installation
