Blasted contractors that cobble stuff together to save 50 cents. Relatives in their two year old house opened the meat filled freezer in the garage to find a warm rotting supprise.
They thought the freezer died, hauled the stinking thing away and rerplaced it with a new freezer, only to find no power at the garage outlet.
They called an electrician to find the problem, as no breakers were tripped.
The electrician found the garage outlet piggybacked onto a basement bathroom GFCI about 100 ft away.
