A plus point is having a separately fed annexe, some where to run a
lead light from and more importantly, somewhere to boil the kettle!

I did look at just fitting the RCBOs into the CU and not bothering
with the terminals, HA!! not a chance, it is cramped even with just
one single L&N from each RCBO Never again!

Any way, thanks to all for their advice a while back, it was much
appreciated.


Photos please if you could be so kind


I'm not sure that I am brave enough to do that, but here goes.

Taken with a rather washed out phone. The spaghetti to the right is
alarm and door bell wiring. The 3 terminal combination on the right
hand side of the DIN rail is for the smoke detectors and their
interconnecting line.

Yes there is still an MCB in there, not too sure what to do about that,
it is the feed to the garage, about 3m of internal cable to a 2 way
"garage" CU with RCD and 2 MCBs for lights and power. Ideas please?

No requirement (in fact it would actually be a disadvantage) to have RCD
protection at the head (assuming its not a TT install) of a submain to
another CU. Its better discrimination of a leakage situation on a garage
circuit causes a tip there rather than at the house CU.

There is about a 2" gap behind the CU Don't look too closely at the 2
copper pipes to the right, they are central heating, when it was put to
bed the cabling was cable tied together and away from the pipes.

All thoughts, comments etc. most welcomed, what ever they maybe.

All in all very neat and tidy[1]. It can be very difficult with so
little working room using tall RCBOs in many CUs. Assuming the boxing in
will cover the wire entrance to the tops of the tops of the CU/Din rail
box there is no need for additional packing to fill the gaps. Else you
would need something to close off the gaps.
