Some basic wiring links for you. I hope they are helpful http://www.acehardware.com/sm-adding-new-electrical-wiring--bg-1284868.html http://www.ablegroup.net/BasicWiringDiagrams.htm http://www.epanorama.net/documents/groundloop/why_grounding.html http://www.hometips.com/articles/sunset_books/complete_wiring/circuits/electrical_grounding016.html By all means not the end all on grounding. I threw in some other diagrams to get you familiar with the way simple circuits are built. Hope it helps/ W

Ok, Is this more like it? 1 x 2 core wire daisy chained to eack GPO (hot and Neutral) 1 x 1 core earth return of each individual GPO.

Pretty much. But if you have two sockets in the same physical wall box, then you can just bridge the grounds on those two sockets together, and run one ground wire back to the bar in the distribution panel, provided that you use thick enough ground wire to meet code. Or thicker. Thicker is better. They way you have it is fine, but you could save a bit on wiring by using only one ground run for each wall box. ( Of course, if you don't mind supporting the Chilean copper mining industry, then by all means, add the extra ground wire, and run one wire for each individual socket! We folks that live in Chile would be grateful for you extra business! :) )

Sound man and guys, I went to buy the wire for the studio and the guy behind the counter said that it was illegal to run a 2 core cable for GPO's with a seperate ground wire! I explained my reasoning and he finally said that it would have to be colour coded correctly. Which is fair enough. I got a quote @ about $190 for a 100m roll of single core earth and a 100m roll of dual core (neutral/hot) cable. Both are just the standard plastic covered OZ style cable. Is it legal?

Is it legal?

Where I live it sure is! In fact, not only is it legal, it is actually code for retrofitting old residential buildings that were built with no grounding. But I live in Chile, and you don't! :) So you'll have to check your local code for your area. Round about now would be a real good time to have an electrician friend on hand! - Stuart -

When running new wires, it is best to have the hot, neutral and safety ground conductors as close to each other as practicable. That is in the same metal or plastic conduit or in the same multi-conductor cable. For reworking old wiring try to have the safety ground wire follow the same path as the hot and neutral wires.

Lilith, Maybe Google electrical code for you area. Best to inform yourself so you understand the requirements. Find trustworthy people who know the trade. You'll be glad you did. Sorry about the slow response, all jammed up at work. :oops: W
