I have just signed up and tried to post my first topic, but it seems to have been lost in the 'ether', or I made a mistake.
My consumer unit is rated max 60amps and comprises MCB's 3 x30 amp, 2 x 5 amp, 1 x 15 amp. One of the 5 amp is not in use. I propose to to replace gas hob with electric and replace existing electric oven. Depending on the choice of each item, can I replace the spare 5 amp MCB with 32/45 amp MCB or will I have to replace the consumer unit for 100 amp?
