If a cable is run outside of the zones shown with green and blue then it must either be buried to a dept of 50mm or more below the finished wall surface, or comply with regulation 522-06-06 parts (i), (ii), & (iii) (see below)





If the wall is 100mm or less thick then the safe zone also extends to the other side of the wall as shown here in more detail
