i have just had some electricians install some sockets in the loft and the
mcb they told me to buy is only a 16A
instead of a 32A like downstairs sockets ETC.
there are 4 doubles on the loft ring so to speak but these
i done my self all they done was install the cable up there
and install the mcb
16A will be fine, but 20A would be more normal. You don't have to run the
sockets in a ring. You can branch off to your heart's content. Don't worry
about not having 32A available, I don't think you need the ability to run
7kW of appliances up there!
I would not see a problem using a 16amp MCB on such a load, but 20A is
usually used. What sort of electricians "told you to buy" such parts as
MCBs? Supplying these should be part of their service. You would not take a
car in for repair and be told which parts to bring.
You can wire it in any configuration that pleases you. You can daisy chain
each in turn, run as a ring, or branch off in a tree.
Unless you are planning to have a 3kW fan heater up there, I wouldn't bother
changing to a 20A MCB. You'd probably actually get the 3kW fan heater and
computer simultaneous on 16A, anyway.
