I hate metal blanks there I said it I simply do not see the point the cover should stay closed itself and if there were an internal fire the mcbs would melt and the fire would get no further than the metal lid what about earthing are you supposed to drill and bolt an earth onto the blank? Scrape away the paint on the Cu and crush the ends of the blank to ensure good continuity?
I also see no point in a metal board if your going to gland tails into it with a plastic gland or use the huge gaping rear entries without intumescent Sealant round the cables like 99.5% of sparks do.... and even at that the cables themselves are not fireproof !!!!
