Splitting one house into two
Posted: Mon Dec 20, 2021 10:15 pm
Im trying to wrap my head around a job im approaching where an existing single storey house is adding an extra storey.
The goal is to have two separate apartments each with their own electricity metering. Ideally, the existing 16mm underground cable is re-used, taken to a meter box with the two meters, and then split off to the relevant submains. I haven't approached the network yet but cant see a problem with this unless someone here can tell me otherwise. The two apartments would be considered one installation? The meter box would be the distribution and MEN point.
My other query though is maximum demand. Do the two apartments have to be fused to a total of less than the 63a supply? ie two 32a (which is actually 64), or one 40 and one 20?
Ideally I would like one at 32a and one at more like 50a.
However going by maximum demand calculations using multiple units, demand is pretty low except for an EV charger in one of the apartments pushing it up. Hope that all makes sense and any guidance appreciated. Thanks!
