Electricity IGA: What is and what is it for?

1 What is IGA of electricity?

It is a fundamental component in any residential electrical installation. It works as a silent guardian, monitoring the electric current that flows through the circuits of your home.

Its main function is to detect anomalies and, in case the current exceeds safe limits or a short circuit occurs, automatically disconnect electricity. This preventive action not only protects your electrical installation, but also minimizes the risk of fire -related fires.

2 What is the automatic general switch (IGA) for?

As we have been detailing, the IGA is an electric lifeguard. Its crucial role is to protect both the electrical installation and the inhabitants of the home. By automatically disconnecting the current in risk situations, the IGA avoids severe damage to the equipment, preserves the integrity of the cables and considerably reduces the probability of serious incidents. In summary, the IGA is a tireless defender of electrical security in your home.

3 How many amps is the automatic general switch (IGA)?

The capacity of the IGA is expressed in amps (a), and in Greenice we always say that choosing the appropriate amperage is crucial.

Households commonly use Igas of 10, 15, 20 or 25 amps, depending on the required total electric charge. The precise selection guarantees that the IGA efficiently protect your installation without unnecessary disconnections.

4 How is a single -phase single -phase IgA:

The choice between a single -phase and three -phase IGA is based on the type of electricity supply that feeds your home. These two variants serve to manage different electrical configurations, and choose the correct one is crucial to ensure effective and safe functioning. Let's look at some examples:

Single -phase IgA example

Imagine a small urban apartment that works with a basic electricity supply. In this case, the home is likely to be connected to a single -phase electric grid. A single -phase IgA would be the right choice to protect the electrical installation of this type of housing. This switch would manage the electric current efficiently, guaranteeing the safety of appliances and devices connected in a single -phase electric supply environment.

Three -phase IgA example

Now, consider a larger home or a commercial establishment that uses heavy machinery. In this scenario, it is likely that electrical infrastructure is based on a three -phase supply to meet the most intensive energy demands. Here, the right choice would be a three -phase IGA, designed to manage the complexity and variability of three -phase electricity supply. This type of switch would offer the necessary protection in an environment where the distribution of the electric charge is more robust and diverse.

The importance of the correct choice

The importance of choosing the correct type of IGA lies in the compatibility with the existing electrical infrastructure. A single -phase IGA would not be effective in an environment with three -phase supply and vice versa. The incorrect choice could result in poor performance of the electrical system and, what is more critical, in inadequate protection against overloads and short circuits. This highlights the need to carefully evaluate the type of electricity supply of your home before selecting the right one, thus guaranteeing a safe and efficient electric environment.

5 How to choose an IGA in each case?

Selecting proper implies evaluating the total power of connected electrical devices. In Greenice we recommend you consult an electrician who has the electrical diagram of your environment to determine the necessary capacity and select an IGA that efficiently protect your installation.

In addition, it considers factors such as location and environment to guarantee the durability and effectiveness of the IGA in your home.

6 What differentiates an IGA disjunct?

The main difference between a disjunctr and an automatic general switch (IGA) lies in its function and scope in an electrical system.

A disjection protects specific circuits, allowing manual or automatic disconnection in cases of overload or short circuit. On the other hand, an IGA operates globally, disconnecting the entire electricity supply of an installation in emergency situations.

While a disjuncture acts at the local level to protect individual circuits, an IGA provides broader protection when addressing the entire electrical system. Both play crucial roles in electrical safety, adapting to different needs within an electrical installation.
