Everything You Need To Know About Wire Loop


Wire loops are integral in the electrical field and they are primarily used to create internal looping between two lights using a single wire which is further connected to multiple fixtures. This technique of looping is majorly done for neutral wires which is a return wire for the current that flows within an electrical circuit- that is, the movement of the electricity from the output device right back to the service panel or the service board. 

Since neutral wires carry charge on their path of return, it does not get heated up extensively. Therefore, it is important to loop neutral wires as they cannot be pulled to longer distances and hence possess distinct neutral wires for every electrical connection. 

Let us illustrate an example for you to help you understand this a little better. For example, your room has 10 separate lights and lighting connections. The neutral wire is looped in between these 10 light connections and the looping is done internally which is then further connected to the main switch using a neutral wire, which completes the whole circuit. This results in 1 single circuit for 10 separate lights and can also be controlled by 1 single switch. This is exactly what is internal looping- as simple as that. 

The Various Advantages of Internal Looping Using Wire Loops: 

Internal looping of wires comes with a number of advantages. Some of these are: 

The physical labor required to complete wiring using wire loops is reduced significantly. Hence, not only material or labor is saved, but also the overall expense is reduced to a great extent. 

  • It is no rocket science, but common sense, the thicker the neutral wire is used to do internal looping, the more durable it is. Therefore, when it comes to looping thicker neutral wires are used. 
  • Internal looping is crucial and if not done correctly, may lead to innumerable wires and color-coding leaving you all perplexed about which wire to connect where. 

What is External Looping? 

Like we discussed internal looping, external electrical looping is also done using wire loops. 

As the name clearly suggests, external looping is done outside the home which is from the main MCB box to the neighborhood’s MCB Box. However, this is illegal, and if it is being done then understand that you are being cheated. Therefore, it is necessary that you understand what exactly external looping is so that you are well aware of whether you are being cheated or not. 

When it comes to external looping, for instance, the neutral phase of electricity of house 1 is connected to the neutral phase of the neighboring house. As a result, house 1 receives electricity much lesser than it generally does. On the other hand, the neighboring house receives a much higher bill (much more than what is being used). So, in order to stay away from problems such as these, external looping must not be done and ensure that you are not being tricked into this either.
