Main cable buried in the ground?

[msodaitis]

hello i got a question , i need to run armour cable from the main meter electric box which is outside to the house and its something like 10 meters and i want to run it trough a car park so how deep that should be buried?

Appendix 4 in the 17th edition
Reg 522-06-03 states buried cables shall be marked by cable covers of a suitable marking tape.It does not state a depth but buried at a sufficient depth where it will not be damaged

As its a car park and likely to have heavy usage over the cable I would go down 0.6m and have added mechanical protection as if it was on agricultural premises 705.522 refers. That way if anything goes wrong later at least you have done your best and although car parks are not covered as a special location it shows you have at least used your brain.

I have read some where that a depth considered reasonable is 500mm+

Don't forget to put the marker tape 150 mm or so above the cable and not directly on it.
