Earthing Schematic Query

me1899 over 3 years ago

Hi all, hope you are well.

Just a quick question on the attached snippet from a drawing - basically for an energy centre and on their earthing schematic all earth bars are shown as follows:

The big text above is the drawing revision text saying the change was deliberate.

I would have thought the above is not right - the main conductor should be connected to the other side of the disconnecting link.

What they have done on site is install a different earth bar as follows:

Disconnecting link is wrong way round?

I am not sure of the rationale behind this?

Any ideas?

Hi Mapj1 - hopefully this helps.

They have put the main connection after the disconnecting link which look wrong.

Surely the main one would be on the first stud and then all the others would be after the disconnecting link.

On their drawing revision they specifically said that they had moved the main connection from the other side of the link.

Don't have much other information - just little snippets.
