Doesn't really matter as I have spare capacity and VD well within limits but I have a sub board fed with 10mm SWA.The sub supplies a 32A socket ring, 6A lights and a 20A radial to a 16A switched commando serving a 10A fixed load motor. All single phase 230V.
Which would you calculate the diversity based on, from OSG table A2;-
1, count (based on 4) 100% of the largest motor, therefore 10A. As there is a 10A motor on the socket at present.
2, count (based on 9) it as a socket radial and use 40%, therefore 4A. Anything could be plugged in in all reality.
3, count (based on 4) 100% of the largest load possible to go on the commando socket, therefore 16A as a larger motor could be feasibly be plugged in.
In this case a 6mm SWA was very borderline to begin with so a 10mm will be used and gives a lot of wiggle room but just wondering how people would approach the situation if things were a bit tighter.
