Don't worry about the difference between 30A and 32A. Neither of them will trip for at least a few seconds even at 50-60A load, so the difference is academic. However, they still trip faster than a cartridge fuse - due to a teensy-weensy little assembly error when I made some recent changes to my control box, I put an earthed bolt through the incoming mains cable. 32A ring main MCB tripped pretty much instantly, but the 13A fuses in mains cable and extension lead stayed intact. I suppose the MCB saved the fuses!
