Wylex NH range Consumer Unit RCD+4,RCD+4,MS+2

[macabethiel]

I have an old Wylex Consumer unit in my garage and the RCB is failing I know it is an issue on these units having replaced mine about 6 years ago.
The unit is obsolete so cant get a replacement RCB module.

I have bought a replacement unit that has Split Load and 2 seperate RCB units so if you get a trip it does not switch everything off.

As I have fish tanks in my Garage extension,pond pumps, freezers etc etc the twin RCB seemed a good idea.

I am a little mystified by the split load section on the consumer unit as it has a B6 30ma NHXSBSB06 connector with a pair of fly leads attached one is a thin white lead and the other is a purple-blueish lead.

I am hoping there are some electicians that can point me in the right direction as it is marked with live outgoing and neutral outgoing.

I have fitted about 6 consumer units over the last 25 years or so and am pretty competent but this modern unit is a new one for me.

Have we any electrician members who can just clarify this bit I guess its some sort of RCBO or similar.

From what I can make out the white lead is the earth connection and the Purpleishblue fly lead is for connecting to the neutral bar then the Live outgoing and Neutral outgoing can be used on my freezer supply or similar.
Presumably this having a white fly lead checks the earth continuity somehow?
A search on U tube etc has not shown me a similar unit.

No lectures please on my competence.LOL
