I've just moved house - so decided to fit a shower - when I look at the
consumer unit its an old tin box thing with BI Callender stamped on it.
obviously in time it looks as though the unit needs upgrading somewhat. But
for now I'd like to just do with it, it has two spare fuses left so why not
My friends a plumber and I normally have enough knowledge to wire up, but
I'm not familiar with this consumer unit. All in all they all do the same
Does anybody have any instructions ideas, Ive attached a photo in pdf format
so you have no problems opening
With all due respect, wiring up a shower circuit isn't a beginner's task.
I would suggest having a new CU fitted alongside the old one, have the
shower connected to it, and then at your leasure you can test and move or
rewire the existing circuits from the old one to the new one.
I didn't know BI Callender Cables ever made CU's, although they made a
lot of the electricity company's accessories such as cable terminations,
service connector blocks, head-end fuse blocks, etc.

Given the age I suggest you should be thinking about replacing
it - and that is a job for a professional by the looks of it.
Also - I may be wrong and get well flamed here - but I think
under the Part P wiring regulations any wiring involving
bathrooms or kitchens MUST be done by a pro, it certainly has to
be checked by one (or by the Local Authority) which could cost
you nearly as much as having it done by one.
As already posted get a new unit.
I haven't seen one of these old BICC boxes for years but I do remember they
are open plan (i.e. bare bus bars inside) with porcelain fuse carriers rated
5-15 & 30a
Also the whole thing was only rated at 60a or even 45a IIR.
For your own safety please don't try and wire a shower into it get an
approved sparky to fit a new board for your shower or as posted a new
One consolation may be the weigh in value of the copper bus-bars in the old
