How old is this rewireable fuse box?

I don't think that will happen with too many variables with different cable sizes and some with one cable or two or possibly three

See in lots of other countries you are only allowed 1 cable in 1 device , it is against their regs / code to 'double up' in a single device.
In these countries it would be pretty easy to simple to make a mcb/rcbo that has a single lever that could accept a single cable up to 6mm ?

For now at least. Though it is not beyond belief they would regulate to 2 cables per breaker (e.g. RFC or two light feeds) and then it would be practical.

Exactly
You could have Single lever and Double lever
Or
Do away with the RFC and have all Single lever
In a modern board you don't really need to double up feeds like you had to in the old smaller way boards

I would do one step further and do away with the single screw type busbar and make all breakers rcbos plug in with back stabs so their is no exposed bar anymore

 

[pc1966]

I still think the RFC has its place, more so given the move to expensive AFDD and so a good way to have enough sockets without too many circuits.

But it is disappointing we don't have plug-in RCBOs with live and neutral both having shrouded busbars, and to make them all follow the same damn standard for it!

But two cables of what CSA it would certainly make the configuration of a 32A MCB / RCBO interesting

Why lose the versatility we have now

Plug in breakers can just as easily be swapped out / moved around as breakers that screw to a traditional busbar

Not sure, but some spring connection DIN terminals cope with 0.2mm to 10mm which would cover most domestic cases.

A sensible approach would be based on the rating, so 6A would only need, say 1mm to 4mm, where as 50A would be something like 6-16mm.

That's assuming you can get a board of sufficient size in the space vacated by the old board

That was my first DB… sparky said have a go @ connecting it,,, was a 4 way with 16mm tails in a council house..nightmare

In answer to the thread title.....

Very old.... if found in a house.....
Not old enough..... if found in Lucians museum


Concerning MCB's with WAGO style connectors... If you remember, i worked in a german built kit house, and the breakers had push-in springed connectors... 2 per breaker... Photos are on here somewhere. Had to be a 48 way board or something.... Everything was done on radials.... to individual outlets in some instances.

I have Hager board in use in a shed that has push in terminals for the neutral an earth bars.

 

[SparkySy]

Yes I've used some Hager boards and GEWISS that had sprung terminals for the neutral & earth connections, they were very quick to terminate, don't see a problem with them at all, no more getting the torque elbow out to do them up!

Here is a consumer unit? from a Huf Haus that also uses those push in terminal MCBs. (sorry it's a bit blurry)
