Hi guys. Am I right in interpreting the regs with regards to rcds that they need to be rated equal to or higher than the main supply fuse? So not to overload them? Or am I reading it wrong?
Thanks on advance.
 
Well that's the thing I cant seem to find any manufacturer that does a type apart from hager.
Lewden... fitted a couple so far. Good price, nice quality, loads of room and a spare SPD slot right at the end (longer than the busbar). The only thing I don't like are the square grommets but hey, I'm warming to them.
 
Hager do type A RCDs and RCBOs
Lewden do type A RCBOs
Wylex do type A RCDs and RCBOs
CP fusebox do type A RCBOs and are a cheap and popular option at the minute.
SBS trade sales do type A RCBOs

There are probably others too.

I should confess, I'm a pretty new Lewden 'fanboy'. but really like Wylex too. The only brand I'm beginning to loath (for CU's) are 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!

I've been using Lewden RCBO boards for a couple of years or more now. Can't complain at all, apart from maybe their SPD could be a bit cheaper.

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.
