Earthing Arrangements Explained + Photo's

[topquark]

To be quite honest gents I want other members to say things like what TC has said on this thread to expand it into a great source of information for everyone. Please continue with positive posts.

Why? Are you covering DC systems as well?

Do you want me to start on that?

Just a quick point as this is for training purposes Paul, on the drawn TT system someone may think that water and gas do not need earthing! I know it's a stupid point but someone will..................!

Edit:- As kindly pointed out to me it should read bonding not earthing!

Let's just keep to domestic earthing systems for now lads. I know this is basic stuff but its somewhere that the learners can Google and learn more than in a book from us lot.

It's worth the effort IMHO.

Thanks for this thread its great to see some real life pictures, rather than just the pictures in books. One thing that took me by surprise in the transition from books to real life was that the main earthing terminal is sometimes in the CU in real life, rather than a totally separate earthing bar which how it is normally illustrated.

that used to be the norm years agoo. it's only in the last 10-20 years that a separate MET has become more widespread.

Is there a reason for this? Is it easier to measure Ze? Or the manufacturing of cheaper CU's? Or is it just the way it is?

What are those yellow, blue and black things!:biggrin5:

You did say you liked what TC was doing! Lol

Air conditioner and Tel, these are the things that I'm on about. It's great learning from books to pass an exam but its a different world out there once you pick up your tool box and go to your first job.

Has any other members got main incomers photos? Post them up.
