Browse Forums General Discussion 1 Jan 22, 2022 1:42 pm We are looking for what the Australian Standards are for buried High voltage electrical conduit ? We hear it is 60cm, with Safety Tape being laid 20cm Above the Conduit to Warn people of the impeding danger below. Dream Big, Work Smart, Not necessary Hard, and be kind to your Mum ! Re: Australian Standards for Depth of Buried High Voltage El 2Jan 22, 2022 2:37 pm Each state has it's own electrical standards, it's not an Australian Standard. If you google the electrical standards for your state you will find the answer. 600 deep for an open trench with marker tape above as you have stated is pretty standard and will most likely be correct but it depends if it's a shared trench and exactly where it is located.

There will only be Low Amp 240V AC feed and 100~800V DC running in the Conduit Trenches. I will go & try a few different searches, but found the Australian Standards site want to be Paid hundreds of Dollars, for what should be FREE information for Safety information.

The Doc's should assist our Rural customers looking to build a Large On-grid Systems we supply equipment to. We are finding many Rural people are looking to set up Solar Farms for a long term income.

Re: Australian Standards for Depth of Buried High Voltage El 8Jan 23, 2022 2:24 pm The entire system would need to be installed and signed off by a licensed electrician anyway, including all trenches for conduits. The licensed installers will be completely up to speed with the requirements in your state.

Knowing what the Conduit Codes are is not Rocket science, it is simply digging a Trench to Code & then engaging an Electrician to Tick off the Installation. However, as 90% of Farmers are only interested of getting Totally rid of there Total Power, and it in Not worth the Puss-n-Pain of heading down the CEC path. As if there System is installed Off-Grid & Behind-the-Meter, you can give the Distributors & Retailers the Bird !
