If you read the original post you will find the trench he is talking about is inside the building to carry conduit not outside so 30mm is fine.

"the vast majority of electrical tradesmen who work for companies like ergon, energex, country energy, transgrid and the like...whilst deemed competent to work on HV installations are not 'electrical contractors' so they can't work in residential installations"
One of the main reasons for this is the cost of maintaining a contractors licence when they don't need it is very high
My SIL is in this position but he does keep his licence as he makes a bit off it doing the odd domestic job on the side,

In my previous posts I had not read AS3018 or reread AS 3008. Now I have a better understanding of what is involved in the job and will continue to research the options finding out the pros and cons of each one. Everybody thank you for the advice.

Thatirwinfella maybe I didn’t use the right terminology and should of wrote a 30mm width x 30mm deep channel instead of trench in the wall. I had hoped everybody would understand by the size of the conduit 20mm what I meant.

Thank you Ashore for pointing that out.

Sorry for starting the debate about non electricians doing electrical work.

Hi Guy,

Isn't it non government personnel who prosecute such people?.

Cheers

there are also seperate licence requirements in most states for low voltage <500 [i think] and high voltage >500 [again, i think]. the average joe blogs domestic who rewires your house or does new homes is unlikely to have the high voltage licence, and many high voltage guys are unlikely to have a low voltage licence. However, there is the crossover in heavy industry. A lot if it is different regulations, some of it would be revenue [but thats the inner cynic in me]

Most if not all of those with high voltage certificates in NSW have passed during their training the necessary courses to get them a ( locally called in the game ) a contractors licence , this allowes them to work on low voltage stuff wire up domestic new and existing homes etc , but as I said they dont keep their contractors licence because the cost is too high, and thats not the cynic in me its just another way for the authorities to generate revenue
BTW there are also diffrent rules when you go to sea , I was quallified to work on 3.3kva and anything lower , switch boards , rewire whatever , but on land unable to wire in a GPO, and for those who are quallified and understand marine power generation and distrubition this land based stuff is a doddle
