but come on Allan...the roles each play havn`t changed with time ...have they....

If you'd asked me that in my apprenticeship 40 year ago I would have said you were talking rubbish.................we were taught to 'earth bond' and at that age we didn't query it.
I was working underground mate............7 mile under the north sea..............everything was extraneous and wet lol.
We ensured there was a good earth on all the equipment by bonding everything...............hence the term 'earth bond'
Twas ELCB's in them days.

Wasn't until I came to the sunlight that I started to understand the difference between bonding and earthing and it still 'shocks' me how many working sparks don't know the difference to be honest.

and with good reason n all...take a look at some of the past chief examiners reports for the old 2391...
time n time again its `wrong terminology`....`incorrect terminology`.....`lack of understanding of terminology`....`wrong naming of test instruments`....`lack of understanding of earthing & bonding arrangements`...
