Now, many people are going for tripped GFCI receptacle than the traditional fuse. Unlike the traditional fuse, where copper wires were used in the contraption and in case of overloading, automatically snapped up. This ensured that electricity was off before a fire could start.

In GFCI receptacle, there are two vertical slots and a round hole posing as hot, neutral and ground. Electricity always pass from high-conservation to low, and thus in case from hot to neutral. If it is the other way round due to problems in integrated circuit, it will snap in razor fast time.

This generally happens in bathrooms or kitchen; former because of profound water and later because of profuse use of electronic appliances like mixer and oven. Don’t use shallow boxes for its installment. See that wiring connections are done well and neutral wire does not connect with earthing. That would be fatal to your GFCI receptacle.
