I was wondering if anybody could shed some light on what the minimum depth that electrical cables had to be buried outside to get code of compliance/to be signed off in 2008?

 

My parents had their driveway replaced and we found that the electrical cables/conduit supplying some outdoor lighting was sitting directly below the poured concrete when the old driveway was excavate.

 

 

 

Thanks in advance.

AS/NZS 3000:2007 Applies

 

Assuming CAT A or Cat B wiring system and poured concrete no less then 75mm = 300mm depth

 

otherwise 500mm if less then 75mm of concrete.

 

Get an inspector to check if your not sure.

Thanks for the reply

 

I will search the standards.

 

It was for 240V cables.

Was the concrete poured over the conduit or did the conduit come later? My neighbour's Telstra coax install was thrust under our drive. Whatever the intention was the drill seems to have just come up and scraped along the underside of the old concrete. Luckily it was possible to cut a slot and push it down out of the way of the new concrete.
