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…
Coronavirus is the buzzword. We are making history in our current state of global pandemic. If you’ve been living under a rock, COVID-19 is a disease that affects the respiratory cells. More specifically, SARS-CoV-2 is the virus that enters the respiratory cells, replicates, and proliferates throughout the lungs, causing pneumonia. We won’t get too deep in the science, but let’s talk about what’s happening outside and what this means for electrical contractors…

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…
This General Electric Armor Clad (AC) plug is an older bus plug version that’s been replaced by the newer GE Spectra bus plugs. The AC plug family is one of the most popular GE bus plug systems. This family of bus plugs has been in the market for many years. The 600V line are the most popular varieties in the family. They have amperages that range from 15A to 800A.

In 1887 Nikola Tesla invented an alternating current (AC) Motor to harness the power of electricity. It is a great invention but not as useful unless operators could turn the motor on and off. Therefore the “knife switch” was created, which connected the power to the motor when the operator manually pulled the switch to the “on” position.
