Top Reasons Why Enclosures Are an Electrical Necessity

prolog February 16, 2018

Electrical enclosures are used to protect both the wiring system and people with access to them from danger. Electricity, although very useful every day, also has its drawbacks when mishandled. The use of electrical enclosures is no longer a luxury, even in residences. Over the last few decades, they have become an integral part of any electrical wiring system. Luckily there are a lot of enclosure manufacturers that offer customers top quality enclosures, whether they are made of metal or plastic. These enclosures, including Gewiss enclosures, are designed such that they have a long lifespan despite being exposed to harsh conditions such as changing weather and other elements.

Protection from the Elements

Harsh weather, dust, dirt, rain and other environmental elements are kept out of contact with the wiring, which prevents it from getting damaged, something that can eventually cause harm or damage not only to the devices the wires are connected to but to the people who handle the wiring as well. Debris and external elements, when they come in contact with electrical wires, can cause short circuits and physical damage to the wires.

Protection from Electric Shock

Enclosed wires protect people from accidentally coming into contact with them, causing electric shocks. Shocks can be fatal, especially if the voltage of the wire is very high. A lot of workers and even homeowners have died or been injured due to exposed wires at work or at home.

Wires are Organised

Exposed wires tend to tangle with each other, making it hard to identify which wire is which, especially if they are of the same colour. Enclosing them in an electrical box makes them a lot more organised, and tangles are avoided. It is also easier to identify specific wires.


Plastic enclosures are good insulators, and wires need to be housed in a box with the right temperature to prevent them from becoming heated or cooled to the point of malfunctioning. Many users prefer plastic enclosures for this purpose, as metal enclosures are good conductors, and need to be grounded beforehand.

Fire Resistance

Metal enclosures are fire resistant. Wires inside this type of enclosure are protected from fire, thereby avoiding further damage. Wires affected by fire can make it a lot worse.


Metal enclosures are durable. They can last for decades without having to be replaced unless intentionally damaged, which can compromise the housed wiring.

In conclusion, it can be said that no establishment can function without the use of either metal or plastic enclosures. Although they may have some disadvantages, they are far outweighed by the benefits that can be obtained from them. There are electrical standards that must be adhered to when choosing the type of enclosure for a specific use. There are ratings that indicate if an enclosure is suitable for a certain purpose and the number of wires to be housed.
