Have the rules for ring mains changed over the years?

[rewireIT]

Sure, what I actually had in mind was if there was only a 4 way rewireable Wylex there in the first place the space for a replacement can be limited (if of course the replacement occupies the same spot)


In a small house where the kitchen is the utility room, you might have a dishwasher, washing machine and tumble drier all on together for over an hour. Ironing the previous load while the next one is washing and drying. A cuppa, kippers on toast. It's not a given that a 20A circuit won't get a little warm!
I don't disagree that other designs work, and multiple radials is certainly possible, but it is a convenient and resilient circuit for variable loads.

Aside from their ability to 'just get on with' periods of heavy use, they are probably the circuit that it is easiest to prove is in an excellent condition and discover modifications via the extensive tests that are possible.

To clarify, I don't think anyone is saying that we can't possibly do without them. It's about whether there are benefits to choosing to use them.

I much prefer how they do it in France, their electrics are much nicer. Their CU's are nicer too, good old double storey jobby.

No because that is a stupid argument.

Europe not having rings despite their rules being made up by dozens of countries of expert bodies proves we don't need rings. End of story.

And our rules were also made by experts, experts who created what is widely regarded as the best designed and safest general use plug and socket system.

The ring circuit was developed due to a particular set of circumstances in this country and if they had occurred in other countries they would likely have adopted the ring circuit too.

By those in Britain.

I do like French CU's. Let's agree on that!

I do like French CU's. Let's agree on that!

They're mint. Nice little plastic stop screws that turn for a snug fit, wago'd earth bars, double pole breakers, main switch at origin of supply, and miles more circuits to put in meaning more money.

What's not to love.

I like their toast….. and their onion soup.

Their version of electrocution is to die for.

Not just in Britain, as far as I know they are regarded that way in many places.

Are you aware of a better general use system?

I wouldn't be adding more circuits to a re wireable Cu.

In a small house where the kitchen is the utility room, you might have a dishwasher, washing machine and tumble drier all on together for over an hour.

Having all those appliances on one circuit is wrong anyway, whether it be a ring or radial.

I don't disagree that other designs work, and multiple radials is certainly possible

Possible ? Radials are the most common circuit in use and installed.

it is a convenient and resilient circuit for variable loads.

So is a radial

Aside from their ability to 'just get on with' periods of heavy use, they are probably the circuit that it is easiest to prove is in an excellent condition and discover modifications via the extensive tests that are possible.

Prove is a bit of a strong word ?
You can't prove any circuit is in excellent condition just using an MFT.

To clarify, I don't think anyone is saying that we can't possibly do without them. It's about whether there are benefits to choosing to use them.

There are benefits to using a Ring final, there are also benefits using a horse and cart compared to a van.

In what way are the electrics nicer?

And what makes their CUs so much better?
