About a month ago i ran a spur to feed a socket in my garage,after
connecting and checking i switched on mains supply.The mcb that supplies the
ring the i was using sparked and tripped out,after checking all connections
that i had made i tried again.This time everthing seemed ok with no trip.The
trouble i am having now is that the same mcb trips out about once a week for
no reason.This has happened twice in the middle of the night with no
switches used.An earlier request for help for a similar problem suggested a
fridge/freezer coming on to be the cause,the mcb i am having trouble with is
not on the same circuit as any of the kitchen appliances so this could not
be the cause. I will be gratefull for any theories about my problem
..Thanks for any replies KEITH
