Thanks ericmark and Ban-all-sheds for the info.
I just had a read through of this: https://www.tlc-direct.co.uk/Book/3.8.6.htm
I will ditch the MCBs. I will keep the spur though as it is conveanient as a switch and connection point for the cable.
With regards to the size of the box, i wanted it to be big enough so that there would be space for some of the adaptors/cables
that i would need to take with me when i went camping.
