Have found various ref. to elec. conduit depth for open ground (500mmm+), but nothing on running cable/conduit from house to garage under concrete drive way (a run of approx 2.5 - 3 M.)
The cable that exists is just a single 2.5mm^2 tapped into the "ring" (kitchen - spur) and running out the wall, in fresh air to the garage soffit board and inside! (not even 8 Ft+ above ground!!) does have seperate fuse board, but seems obsolete at moment if on a 30amp circuit already (unless it is 15amp... haven't checked yet)
There are drainage pipes around this area so wanted to know the minimum depth under concrete (I assume that it is at least 100-150mm thick)
Will contact sparky when suitably informed (want to know jobs worth, etc.)
Any help guys... cheers.
