Hi guys
as u know I'm learning at the moment so please don't berate me if I'm wrong. My friend called me to say that he was home when his whole flat went out at once, when he went to his cu (old board with ceramic fuses maybe?) he said the knob on the far right had turned to off. ( i dnt know what type of switch this is?) He tried to turn it back on and it wouldn't turn until after several attempts. When he finally turned this knob on all power resumed as normal, however when he went upstairs he noticed his immersion heater was not on and he could smell burning from the airing cupboard he thinks.
Now I said to him that it sounds like a loose connection, possibly the burning smell was insulation? Could be caused by wear and tear, could be something that has bitten into it?
Am I right in saying there sounds like a fault in the immersion circuit? This is on it's own dedicated circuit as shown in the cu by a blue 15a fuse. Has the fault blown this fuse and then tripped the main switch (which i presume is the knob?) due to circuit overload?
Thank you for your help
