Many thanks for the reply.
I have been mulling over the design of mine and plan to incorporate many ideas from your build.
Just placed and order with Chalon for a rotary disconnect switch and two type D MCB's 4A & 10A.
On holidays fo rthe next few weeks so taking viso and some cables, plugs and sockets plus soldring iron with me and relax in the sun while building my wiring looms ;-)
Cheers,
Ian
