Glossary of Workplace Electrical Terms

If you work in the electrical industry, you are likely to hear many workplace electrical terms on a daily basis. In order to function in your line of work, it is necessary to become familiar with these terms. Workplace Electrical Terms for Circuits These are some basic workplace electrical terms that come up often when referring to electrical circuits. AC (Alternating Current): This type of current will alternate its direction many times a second at regular intervals. DC (Direct Current): Current will flow in only one direction. Feeder: These are circuit conductors between the service equipment, the source of a

Electrical Supply: What is a Fast-Acting Fuse?

Fuses work to protect us from electrical faults that could start fires in our homes. If they detect there is too much current running through an electrical device, they block the currents by shorting out. There are different kinds of fuses which can be used in various electrical applications. While a slow blow fuse can withstand high current for short amounts of time, fast-acting fuses will burst immediately when high power voltage passes through it. This article will take a look at some of the uses and applications of a fast acting fuse. How do Fuses Work? Wires get hot

Electrical Supply: What Are Non-metallic Conduits?

An electrical conduit is a tube used to protect and route electrical wiring in a building or structure. It is generally installed by electricians at the site of installation of electrical equipment and its specifications are regulated by the US National Electrical Code (NEC). An electrical conduit is made of metal, plastic, fiber or fired clay. Most conduit is rigid, but it can be flexible as well.   While metallic conduits serve to shield sensitive circuits from electromagnetic interference from enclosed power cables, non-metallic conduits resist corrosion and are lightweight, reducing labor and installation costs.

Electrical Supply: What is a Molded Case Circuit Breaker

Molded case circuit breaker is a protective device that used when load currents exceed the capabilities of miniature circuit breakers. It can also be used in applications of current ratings that require adjustable trip setting that is not available in plug-in circuit breakers or miniature circuit breakers. This article will serve to familiarize you with the functions of a molded case circuit breaker and things you should know if you are using one in your electrical application. What is a Molded Case Circuit Breaker and What Does it Do? Molded case circuit breaker (MCCB) offers electrical protection for a wide

Electrodes – How Electricity Works

When you think about how electricity works, the most likely thoughts that come up revolve around electrodes. An electrode is defined as a point where current enters and leaves an electrolyte. When current leaves an electrode, it is known as a cathode, and when it enters it is known as an anode. Electrodes transport electrons to one-half cell to another producing an electrical charge. The charge is measured with the standard electrode system (SHE) with a reference potential of 0 volts which serves as a medium for any cell potential calculation. Electrons are vital components of electrochemical cells. The Mechanics

How Do Carbon Monoxide Detectors Work?

Carbon monoxide detectors are very valuable for ensuring the safety of your home and family. Odorless and colorless, it is very difficult to tell when carbon monoxide is present. However, this deadly gas can find its way through your home through a number of seemingly harmless sources. When it does, it can cause unconsciousness within minutes, not to mention permanent damage. Find out more about carbon monoxide and the potential harm is can cause as well as what you can do to prevent poisoning with a carbon monoxide detector. What is Carbon Monoxide? Carbon monoxide is an odorless and colorless
