Ground fault and arc fault are sometimes used interchangeably but they are actually two separate things. Ground fault is a type of short circuit sometimes known as “short to ground.” It happens when current going out on ungrounded phase (energized “hot” current) accidentally makes contact with a ground path. Electricity always wants to find a path to ground. Sometimes this unintentional path to ground is a person’s body. Ground fault causes electric shock that could be severe or fatal to people…
