 COMPLETE ZERO ELECTRICAL INSTALLATION (FROM THE STANDARD TO THE OUTLETS)

How to MAKE a ZERO RESIDENTIAL ELECTRICAL INSTALLATION

Have you ever stopped to think about all the steps to make an electrical installation from scratch? Do I start thinking about the project or do I run the cables?

First or do I mount the frame and when do I close the sockets?

Well, in today's video we're going to show you step by step how to make an electrical installation from scratch, safely, quickly and professionally, thus avoiding future problems.

The 1st STEP to carry out an electrical installation is to carry out the planning of this work.

It is very important to define together with your client which appliances and other equipment will be used in the residence. In addition, it is necessary to define the number of outlets and lighting points.

And why do we need to do this? Simply because that's the only way we can define the amount of circuits and the power needed to feed them.

In addition, we were also able to design and predict circuit protections, cabling and general protections, and thus define the size of the QDC, which is the property's distribution board. It is even at this moment that we can predict what the entrance pattern of the building will be.

With the number of outlets and lighting points defined, in addition to the location and size of the QDC, we can move on to the 2nd STEP, which is the installation of passage boxes and conduits and conduits, as you prefer.

Conduits are ducts that protect electrical cables, and they are installed on walls, slabs and floors, and must have a specific type of resistance for each installation, according to item 6.2.11.1.3 of NBR 5410, which mentions that “They are only conduits that support the deformation efforts characteristic of the construction technique used are admitted in built-in installation.”.

We generally use the yellow conduit on the walls, orange conduit on the slab and what is known as HDPE (High Density Polyethylene) duct for floors directly buried in the ground, O

Yellow conduit is the most fragile and HDPE is the most resistant.

Another important detail is to choose the passage boxes, so that they are resistant and suitable for each type of installation.

And speaking of adequate, a very important item to ensure the safety of building users is electrical grounding.

The electrical grounding system serves to protect people and people from the risk of electric shock. It is responsible for directing the electrical currents that may arise in the event of internal equipment failures or short circuits in the electrical network to the ground.

The TN-S type grounding is one of the most common and recommended for use in homes.

And so we finish the infrastructure part of our installation.

And with the infrastructure ready, we arrived at the 3rd STEP, which is the passage of electrical cables.

As we've already planned which cables and protections we're going to use, now it's time to run these cables. A tip I give is: always start the cable routing from the QDC. From the QDC, the cables will reach the junction boxes on the ceiling and from there they will be branched to the boxes on the wall.

Remembering class, always respect the maximum load capacity of each circuit, so we avoid overloads.

Cables passed, the 4th STEP is to make the closures, installing the sockets, switches and light fixtures. It is at this moment that the helpers start to make all the closings and the electricians will assemble the QDC with all the circuits and protections.

Personally, I consider this one of the best stages of the work, because putting together a beautiful and functional painting is like my signature on that work, which I consider to be art.

And finally, STEP 5, is to perform tests to ensure that everything is working correctly. In the panel we test the circuit breakers, the DR and also if there is no continuity in the DPS. As for the sockets, light fixtures, in addition to testing the operation, we also test the polarities if they are correct, if there is a voltage drop and so on!

  And after this class, what can we conclude my dear?

To do an electrical installation from scratch, it is necessary to do some planning, a little technical knowledge and a lot of attention to standards and regulations.
