Is there anything that says an MCB rating for a ring main has to be 32 amps, could it be 16 amps? I want to put my kitchen on its own circuit but the MCB's are no longer made by Crabtree but I have two unused 16 amp MCB's. If I use the 32 amp that is currently the downstairs ring main for the kitchen then put the front room/hall on one 16 amp ring and the living room on another 16 amp ring would I run into problems?
