[QUOTE="Sidewinder, post: 471128, member: 9512"] I've run the selectivity study for you, using MK data in the design software I use. In the main board, C32. In the sub board, C16 & B32 on separate circuits, 15m cable runs, 4mm sq radial on the C32, 2.5mm sq radial on the C16. The cable sizes and lengths don't have any bearing really on the selectivity between breakers. C32>C16, partial selectivity achieved C32>B32, no reasonable selectivity achieved [/QUOTE]
