MK - who should be top. Their boards are rubbish (IMHO) now (for 18th) - everything else they make is great but they are falling behind big time - don't even make an SPD yet - but endorse Surge Protection Devices for use in their boards... messy!
Yes, their CU's aren't up to the general standards of MK..........but CU's have never been their strong point. Never touch them.
The trouble with MK is that many of their 'superior' accessories are no longer superior....even for superior prices
 
Rated diversity factor (RDF) / Values of assumed loading
1way = 1.0
2way – 3way = 0.8
4way – 5way = 0.7
6way – 9way = 0.6
10way and above = 0.5
Note: RDF only applies to continuously and simultaneously loaded circuits.
In principle, this means adjacent circuit-breakers having a load ‘on’ time exceeding 30 minutes or where a load not exceeding 30 minutes has an ‘off’ time less than the ‘on’ time, will need to have the rated diversity factor applied as indicated.
