Installing a Home Electrical Installation

Electricity is the most important source of energy for all humans. So it is important to have a home electricity installation to flow through this one energy source to be even more useful, for example, to illuminate the house at night, turn on the television for entertainment facilities for families, and others. But unfortunately, many still underestimate the correct installation procedures, for example in densely populated settlements. You can see the cables overlap from one pole to another, then play as long as you connect into the house. In fact, the wrong installation can be fatal, such as short circuits and fire.

Of course, you don’t want it if the electricity will bring disaster to your dwelling in the future. Therefore it is important to make sure all home electrical installations are installed correctly and safely. How to? The things that need to be taken into account when installing a home electrical installation. Installing an electrical installation must be correct and according to the rules. Of course, to minimize the risk of an electrical short circuit to fire. But before discussing how to install an electrical installation, it’s good to pay attention to some important things first.

Knowing the area of the house and the number of rooms

To be able to drain the entire room with the electricity needed long cables. Therefore, it is important to measure the area of   the house and the amount of space available to determine how long the cable is needed. In addition, you also need to know how many lights, sockets, and switches are in each corner of the house.

Knowing the amount of electric power

One of the most important components in a home electrical installation is the Miniature Circuit Breaker (MCB). This component has a function for the electric current protection system in anticipation of overload. With MCB, the risks of short-circuit to the short circuit can be overcome. Now to determine how much MCB is needed, of course, you need to know first how much electricity is the house. The greater the electrical power, the more MCB must be installed. The goal is that if there is minor damage, it does not spread to other installations.

For example, if you have a two-story house, then electricity on the first floor is damaged, the installation on the second floor has no effect. Don’t get me wrong, the more spacious our home would ideally require greater power too. Consider the costs carefully if you decide to increase the electrical power of your home.

Preparing materials and components needed

The electrical installation can work well thanks to the important components in it. The following are some important components and materials needed.


Earth Leakage Circuit Breaker (ELCB)

MCB and ELCB boxes


Electric socket

Power cable



Embodies (junction box)


Know the proper home electrical installation wiring

In an electrical installation, there are many cables that have different sizes and functions. Use it appropriately and carefully avoiding the risk of short circuits and short circuits. In addition, make sure that the cables used are SNI standard. If the cable has SNI standard, it means that its worthiness and safety are guaranteed.

How to install a good home electricity

After knowing the most important things above, now is the time for us to discuss the steps to install the electrical installation in your home. But first, make sure first that your house has installed KWH and MCB from the PLN. Because electricity can only be received if it has been connected from the PLN cable.

Designing electrical installation lines

First, you certainly have to design an electrical installation line at home. Which rooms you want electricity, for example, a room, kitchen, living room, family room, bathroom, and other important spaces.

Installing pipes for power cables

Once designed, you can start breaking down walls to insert pipes inside, including the linen and switches. Measure the height of the bed in accordance with their needs. But try at least 125 cm from the floor in order to avoid the reach of small children.

Start installing the mainline cable

The installation of this mainline is measured from the MCB box, then connected to the most recent socket. This main cable can be installed on the roof or top of the ceiling so as not to be seen. Then later the cable will be connected to the electric pipe in the walls that have been broken down.

Connect for switch cables and sockets

After the mainline cable is channeled, then the cable from the mainline is forwarded to walls that have been broken down for switches, sockets, and lights. Connect all the cables in accordance with the purpose.

Install the components

After the cable extends into the wall that is broken into pieces, all that is needed is to install the necessary components, such as a socket, switch, and a header for the lamp. But make sure that all cable and pipe connections are covered with insulation to be safe when electricity is running.

Home electrical installations can begin testing by activating the MCB

After everything is installed neatly, just activate the MCB. After the MCB switch is in the on position, please turn on the switch and the lamp to test whether the electricity is successfully delivered or not.
