[QUOTE="Doc Hudson, post: 493233, member: 1607"] Welcome to the forum. It sounds like you have a perfectly functional consumer unit doing exactly what it was designed to do, protect you & your property from electrical danger. What you refer to as RCDs I think are MCB's and what you call the main circuit breaker is an RCD. RCD's must remove the power in less than half a second if they detect a fault as small as 30ma passing to earth, as that is sufficient to kill and adult. You need the RCD verified first of all, then a whole list of cable tests with various meters to get a better understanding of what may or may not be going on. The incoming supply & earthing arrangements would also need checking. I would guess the biggest problem you have is a poor design of fuse box with just a single RCD protecting multiple circuits. Which does not comply with regulations about minimising inconvenience in the event of a fault. Best solution is employ a competent electrician with the proper test gear to start getting some facts established. Where about are you? we may have a forum member near who could assist? Doc H.
