Guide To Types Of Electrical Box

An electrical box is sort of a junction where exactly all of the electrical wires which link many electrical devices in a room culminate into switches. These switches serve as an interface for user to operate the electrical equipments, are preset in to the electrical box. Various types of electric boxes are found today for particular needs. Whilst a normal electric box could possibly be enough for a home, an explosion proof electric box is just what exactly you will need for a unsafe site. This post makes it possible to recognize the necessity for different kinds of electrical materials, especially electric boxes.

Different kinds of electrical boxes

Electrical boxes may be set up indoors or outdoors. They come in numerous styles, size and material based on the usage. Normally for indoor application like in your house, these electrical boxes are hidden in the wall, whilst in case of outdoor applications, electrical boxes have to be weather proof and moreover durable enough to guard the switches fitted within from any mechanical stress. The design of the electrical box is mostly rectangle, square, octagonal, or maybe round and are manufactured from either metallic (cast iron, aluminum, steel) or even non-metallic material (plastic, PVC). Plastic or even PVC boxes are low-cost and also easy-to-install however must not be used where metallic cables are used.

Difference between regular electric box and explosion proof electric box

Electrical boxes are important not merely from the aesthetic perspective yet likewise from the security viewpoint. Since these help in covering the electrical wires and additionally protect the users from any possible sparks that could possibly take place due to overload, loose connections or even ingress of foreign particles for instance dust.

Oftentimes these electrical boxes additionally will need to be installed in conditions which can be unsafe and hence they might should be designed in a different way from normal electrical boxes to make them explosion proof. A dangerous location generally entails an atmosphere where flammable or even explosive gases, liquids, or maybe dusts are present possibly all the time or when there is a failure in normal functions.

A typical electrical box which is to be set up in a non-hazardous location has to be just powerful enough to bear the weight of the enclosures and moreover provide safety to personnel towards minor sparks, that could occur because of loose connections or overburden and also give protection against the ingress of dirt / water Or oil and even corrosion.

Although, in case there is an explosion proof electrical box, you need to be sure security of the people, even in the case of a heavy explosion and that is why really should be bigger and also heavier compared to normal enclosures. The joints and also flanges of explosion proof enclosures will need to ensure that hot gases that are formed as a result of an inner explosion are cooled down to a temperature point that if they’re released doesn’t have plenty of heat to trigger another explosion. Depending upon the amount of risk to safety the design of the explosion proof enclosure is further calibrated. Explosion proof enclosures are produced utilizing material having high durability such as polyester, aluminum, and even stainless steel to ensure that in case of an explosion, there’s no external damage.

So now, that you have realized the significance of several types of electric boxes, keep the info in mind when souring electrical engineering materials.
