Got it, massive thanks everyone
Also just found out machine 1 is actually 13a, machine 2, 12a. So downgraded to 32a protection.
When you say L3 for N, this is from my switch onwards, correct? I can't use the L3 line all the way back to the DB can I?! This will not be a balanced load.

The earth will come straight into our PE terminal inside the cabinet from the supply line, it will not go through the isolator. Is this OK? Technically in the event of an earth fault, you probably need to be able to isolate the machine? But if there is an RCD on the DB, it would protect it anyway...
