Could anyone Email me digrams or photos of the type of earthing systems used in these two countries as I teach the potential electrical contractors in Qeensland as well as electrical licence upgrades to electricians who immigrate to Qeensland. This information will help me better understand those country's electrical installations. My Email address is bill.langford@det.qld.gov.au

Can't help with the info but as a Qld contractor I just want to say "teach 'em well Bill". My life may depend on it one day.

I would suggest moving this thread to the non-US section where I know there are those that can oblige.

In the meantime, one of Paul's favourites:-

We have some sketches of the British arrangements in the Technical Reference area:
