Dangers of ring final circuit

[Baker1988]

Hi i have been set some home work from college to find out why ring final circuits are dangerous. I know the obvious that if one leg on the ring breaks it will not be a full ring and the 32 amp mcb will be too big for the cable as it will only be able to carry about 20 amps with out it been a ring which would over load the cable. But i can not find any thing other then what i already new can any one help me with this

Just think,in not so many years, the warning to the customer off some will be, "they are against the law and needing ripping out"

It may give the Wylex fuse boards a bit of a rest

Only joking by the way

Ask your lecturer to look up Buffoon, he may find a description of himself!

the question should of been to find the advantages and disadvantages of a ring final circuit. The question your tutor has set is very leading, and hes tryinmg to force his opinion on you.

IMO education should be about giving you the hard facts, and knowledege for you to make your own decsions.

I was trying to think up a reply then i read yours. Spot on mate, couldn't agree more.

I think you guys are taking this a little too serious.

I've asked similar a question to my students before, not necessarily that rings are dangerous, but more about there opinion to the potential dangers a ring final can create when under the control of "ordinary persons".

and the answer is YES. Ring final circuits are more dangerous.

Yes, we know your opinions on RFCs Your one of these Lecturer's impart and burden your own prejudices on your students, instead of giving the hard facts and knowledge for them to make up their own minds...

There is nothing Dangerous about an RFC, that has not been tampered with!! As far as your students go, keep your own opinions and prejudices to yourself!!! The last thing this industry needs is your personal prejudices being perpetuated along with all the other myths and scaremongery that's out there...

Ring finals are great. It’s when the know nothings come to fault find on them they become a problem! And BTW if I were to do a house rewire I’d still do the lighting in a ring. OK I’m a bloody dinosaur but I’ve never gone back to a fault of my making.
Radials are for the know nothings that can’t do simple calculations.

The bottom line here imho is, as long as you have done the calcs and proven the installation is ok, and as long as no one has buggered about with them andit's been tested properly it does not matter whether the circuit is a radial or a ring it'll be alright
