ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Do we need grounding?

I like to learn about things that may be better (or worse) in other areas. Sometimes we are a little slow about updating the standards, and yes it is just as an hobbyist, but earlier I had to know becaouse we worked with companies in other countries, It was quite a job to read NEC and spot what was important to be OK in both countries.

It is not easy to be a certicated electrician here in Norway and non electrcians ar not alowed to do much here.

Is it any important differences between NZ and Australia?

About the only thing on your list that gets tested is the GFCIs in residential. Most inspectors carry a bug eye tester with GFCI testing capability.
I had an Ecos tester that checked ground impedance.
Ground/earth testing is usually done by an engineering firm but I have only seen it on some state jobs. Toll booths were one. Out in the boonies, a toll plaza is the most attractive lightning target. The grounding system is right up there with radio towers, another interesting job.
Some commercial jobs do get megger testing but not residential..
