    You will get any size terminal block. 25sq won't be a problem. Would a reducing pin be of benefit?

    What's the application

    25sq isn't that big , the board should accomodate it if it's rated for 25

    I'm assuming the earth and neutral are too big for the earth and neutral bars? A reducing pin would suffice.

    Another option would be to install 25sq din rails, terminate the cable and come out in flexible tails.

    Yeah,The earth and neutral are to big,I should of checked the board before purchasing.Think the din rails could be the way to go and come out with flexi as you said.Would 16s flexi be an option

    It's not an uncommon problem. Double check all the terminals. Sometimes there's one larger than the rest. What size breaker is protecting the 25sq? 16sq tri rated flex is good for a 100A

    As the 25sq would be going on an 80 amp breaker

    I remember going back a bit my inspector wanted the main protective conductor spread across 2 terminals

    Something to do with the risk of 1 terminal loosening

    I'm nearly sure he said there was a regulation but I don't see anything in ET101

    I think hes looking at consumer units too much. I see in what he is trying to achieve.

    Not a regulation, can't be done in most cases. Can't be done on Atex equipment.
