The term “arc flash” is used to describe low impedance connections in an electrical system, which allows movement of unwanted electric discharge through the air from one voltage phase to another, or to ground. This leads to a rapid rise in temperature and pressure in the air between electrical conductors, causing an explosion known as an arc blast.

Arc blasts and the resulting heat can lead to fires, pressure waves and flying shrapnel that result in serious damage to life and property. These explosions typically occur without any warning, destroy electrical equipment completely and lead to severe injury or death of personnel present within the boundary of the arc flash.

What Are the Main Causes of Arc Flash?

Arc flash occurs when several electrical conductors are placed close to each other, with significant fault currents flowing through them. In this situation, ionization of the air can take place as a result of various factors – such as differences in potential – which leads to a low resistance path and allows current to flow through the air gap between conductors.

Many people assume that low voltage equipment is safe from arc flash, but arc flash hazard levels may be higher at low voltages, due to the high fault currents. Most incidents that occur in low voltage systems are caused by human error, e.g. a tool slipping while a technician works on electrical equipment.

Arc flash can also be caused due to:

When you sit in the den to read a good book, you probably want some soft lighting to do so by. You don’t want harsh, bright overheads sending a glaring reflection off of the page back into your eyes. Of course, you could use a lamp to read by. However, we suggest that you speak with a member of our staff about dimmer switches and softer overhead lighting options. That way you can enjoy the convenience of overhead lighting without the headaches – figurative and literal – of harsh reading light.

Cooking a nice dinner for the family can be a fun affair. It can also be rather hectic, with timers going off and sauces to keep an eye on, not to mention the action on the cutting board. If your kitchen is not well-lit, there is no way that you can hope to go about your business safely. Under cabinet lighting and adjustable track lighting can give you what you need to see precisely what you’re doing when working in the kitchen.

Some people forget that lighting can be as much about fashion as it is about function. Illuminating original artworks, photography pieces, or even unique architectural flourishes can be a great way to class up your home. We have the right indoor lighting solutions for any such purposes.

Limit switches, as the name suggests, are precision switches that are designed to work as limiting devices. The switch is typically snap-action and designed to sense the presence, absence, or be triggered by an excess or lack of physical contact at the position where it is installed.

The flexibility and adaptability of limit switches to different tasks and environments has made them very popular as components of conveyor belt systems.

Industrial conveyor belts are considered to be amongst the greatest inventions for boosting production, as well as reducing time, costs and manpower requirements. They are commonly used in production, mining, assembly lines and just about every major industry or sector today.

They typically consist of a number of pulleys that rotate under a continuous belt. Some of these pulleys are powered and they drive the belt, keeping any material on top continuously moving towards its destination.

Conveyor belts can be broadly classified into two classes, which are:

These conveyors are used for transporting smaller volumes of material like packaged goods, or lighter materials like boxes.

These are heavy duty conveyor systems which are designed to carry heavier loads or bulky materials, like industrial and agricultural goods.

While conveyor belts can tremendously increase efficiency, they are prone to jamming from over-loading unless the correct safety measures are put in place. Limit switches help prevent this by measuring the height or number of individual products passing through the conveyor system. In case the switch senses an object that may cause an obstruction, it shuts the system down to prevent damage or spillage.

Depending on the environment and purpose, there are a variety of limit switches which can be used in conveyor systems:

Electrical problems have the potential to cause serious injuries and property damage, and should never be ignored.   What may seem like a minor problem, such as a flickering light or a circuit that repeatedly trips could be an indication of a major problem hidden within the walls of a home or business.
