Yes! the orange cable is the same stuff used with the 230v hook up cable, i just cut a piece of as i didnt have any twin & earth. I used another short length to go to a twin socket.
So can you tell from the pics what size MCB's they are, and is the 63A, 30MA RCD acceptable? (i said earlier i had a main switch not an RCB)
