My electrics keep on tripping but it has me puzzled.. started a couple of weeks ago and all ok for a few days but will trip 6/7 times before staying stable again.. the RCCB split load is the one that trips and this feeds the cooker upstairs and downstairs sockets... when it trips turn circuit breakers off reset the RCCB and the swith on the cooker all fine... sometimes try to switch upstairs but wont then will switch.. the same with downstairs.. unplugged lots of things but still happens now and again and when resetting today the is a crackling/arcing noise coming of the fuseboard... would I be right in saying problem is within the fuseboard?? bit lost really as my electrics are very basic........ thanks in advance
