If they are both on the same erf then what you have described is not legal. Where is the municipal meter ?

Special permission can be obtained from the supplier for more than 1 supply per Erf, but they will not allow more than 2 in which case the breakers in the kiosk outside will be downgraded so that the total of both does not exceed 70A.

Each db will then need a double pole mains as well as a supply authority meter.
