I am thinking of replacing our existing consumer unit, to be able
to add a couple of new circuits (garage lighting/power, and a spur for
an electric shower).
Originally I was thinking that I'd have to either get the LEB to do
the final fitting of the tails, or do as a few in this newsgroup have
advocated and break open the LEB seals to wire this bit up myself.
However, when having a proper look this morning I was pleased to
realise that there is a 100mA RCB in circuit just before the CU. It
looks unsealed (although I can't quite see yet how to open it up from
my cursory inspection).
So - assuming that I can get access to the output terminals of this,
it should be safe to trip the RCB and connect up the tails to the CU
A supplementary question - is there any mileage in removing this RCB
and fitting one in the new CU? I'm thinking of neatness, really, since
I shall be fitting at least one RCB (for the garage circuit) in the
new CU anyway.
Thanks for any thoughts
