earthing fault help

[Ryan Kavanagh]

hi guys,

Just need some help with some course work.

does earthing provide basic or fault protection?

Now i know it provides fault protection as the earth is need to trip the circut breakers but im thinking is this a trick question and could it be both? :rolleyes2:

any help is muchly appreciated

thanks

look up basic protection in the bible. ( BS7671 ) that will give you the answer. wish this forum was around when i had homework, but then, the nearest thing to a computer took up as much room as a row of terraced houses, and it worked on valves.

hi,

ive got to the bottom of this now!

yes this forum is great! and they alot of really helpful guys like yourself. Im studying a OCLI course so all the theory side to it is all home study and there course material isnt the best, so ive just had to order 3 supplementary books of amazon to help me.
