Ground Fault and Arc Fault 101

Safety

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…

What’s the Difference Between Short Circuit and Overload Conditions?

Safety

Short circuit and overload conditions are a bit different but they both pose similar dangers. Read on to see their slight differences. Short Circuit – We know that current flows in a path from point A to B – this is considered one phase. A short circuit occurs when current flow deviates from that path in two different ways: phase-to-phase (direct short) or phase-to-ground (ground fault). When current flows from one phase to another, also known as a direct short, that huge amount of current…
