good day,
we have had an electrical fault on the property we live in for the past 8 months
we have gone through 4 electricians and counting

does anyone have any idea

facts
the property has a main house, granny flat and garage
the electricity was previously fed from the house to the granny flat and then to the garage

the electricity trips (mains) outside for both the granny flat and the house simultaneously but only in the early morning and in the evening

we have suggested dew but the electrician and owner are adament that is not the fault

any ideas??????
