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?

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.
