What Are The Most Common Mistakes In The Installation Of A Home Electrical Network?

The first has to do with a deficiency in the design of the installation or network, many times the electrician masters do not put on a sheet of paper the planting of this installation, which consists of a plan or sketch to determine the distribution of dampers, electrical outlets, lighting, etc. Electricians are also sometimes called when the construction of the house is already very advanced, which forces them to mentally improvise the distribution of this network, leading to mistakes.

Another of the most common mistakes happens when you start with the laying of cables, either in their paths, moorings, or in the amount and caliber of them, causing short circuits, energy leaks to some element of the construction, such as conductive tubes, rods, or supply deficiency.

What are the most recommended materials for the electrical installation of a home?

The minimum materials required in the construction of a house are: registration boxes, dampers, outlets, lamps, etc. – and ducts where the wiring passes – which can be either metal for thick or thin wall or PVC, this being one of the most used.

Conductors are also needed, that is, cables with a plastic insulating sheath. The ideal metal for this type of conductor is copper, and there is no more.

In addition, 30-amp knife switches and load centers that use thermomagnetic switches are needed. Generally, taking into account the regulations, both switches must be installed. An element that is of the utmost importance and that few construction companies take into account is the use of the ground system, that is, to have an element that goes to the physical ground, which can be a copper rod or conductor buried in the ground and a bare cable that travels through all the pipelines of the electrical installation.

What can other advice be given to electricians to guarantee quality work?

A first tip is that when working, they do not do it on a wet floor or after having been in contact with water without making sure they are completely dry, because when handling electricity in this condition we are more susceptible to electric shock. Another basic advice is to cut off the mains supply and verify directly that there is no electricity supply, easily with a socket and a bulb.

There are some houses with a ring-shaped installation, where the power is still cut off, we can be the connector of this and receive a discharge. Therefore, you should always have an insulating element, whether on the floor, with rubber shoes, gloves, wood on the floor, or any non-conductive material.

Basic Lighting Living Room Tips

The living room is a difficult space to illuminate. That’s because it contains so many functions from watching TV, reading a good book to receiving friends.

Light plan living room

Lighting makes or breaks the carefully constructed atmosphere. So make sure you have a good lighting plan.

Start by applying the basic lighting. This ensures that everything is illuminated evenly. That there are a few shadows as possible. This way there is sufficient background clarity. That needs your eye to orientate yourself. Less large differences in light intensity ensure that your eyes are less tired.

It is a must that the basic lighting is dimmable. This way you can adjust the atmosphere depending on the use.

Ceiling lamp living room

You can use a ceiling lamp for the basic lighting. You can connect this to the connection point in the middle of the ceiling. Choose a lamp that shines towards the ceiling or shines in all directions.

Often only a ceiling lamp is not enough as basic lighting. We therefore always recommend a second lamp. For example, a standing lamp that shines in all directions. You have to ensure that the entire living room is lit.


By having a lamp shine upwards, the light is reflected back through the ceiling. So you hardly have any shadows. And that is the purpose of the basic lighting. The significant advantage of up lighters is that they do not blind. This is because you do not see the light source.

Indirect lighting living room

Indirect lighting is lighting that is reflected through ceilings, walls or other elements. They soften the shadows of other light sources. Therefore perfect for essential lighting. Many indirect lamps are free-standing floor lamps or wall lamps.

Recessed spotlights in the ceiling

When ceiling spotlights have a broad apparent direction, you can use them for general lighting. So do not opt ​​for those small halogen spots, but the larger version. It is a bit more powerful, has a giant reflector and gives much more pleasant light. These lamps are dimmable but also orientable — ideal for essential lighting.

For these lamps, light sources are available in a sharper light angle with more bundled light. Do not use that model for essential lighting. Well for the mood lighting. So you can finish with one type of recessed luminaire to provide both essential lighting and mood lighting.

Essential Tools For Electronics

To get started in electronics, here is a list of tools described in detail in this article. There are indispensable tools, such as soldering iron, tin, screwdrivers and if you want to make models, hole cards and electronic components (standard) will be necessary.

The Essential Tools Of The Beginner Electronics Technician Are:

-The Multimeter

A multimeter is a device that includes several functions: voltmeter (voltage measurement), ammeter (current measurement), ohmmeter (resistance measurement), diode function (diode test), and sometimes capacity measurement (capacitors) and still temperature (probe).

There are very basic multimeters and others that integrate more functions and especially robustness. The multimeter’s cords are an important element as they are manipulated all the time and we rely on them to guarantee the electrical measurements we make.

– The Mini Drill

To realize its electronic cards, a mini drill is indispensable to be able to fix the traversing components. The drills must have a diameter of the order of 0.8mm to 2mm for the legs of the components (resistors, capacitors, etc.).

There Are All Kinds, On A Column Or To Hold By Hand.

– The Soldering Iron

We immediately think of the soldering iron. The first-price soldering irons plug directly into the socket. They are often too powerful and heat too much. This is especially the case of irons “pistols” that are 100W and more. There is a wide variety of soldering irons.

Some brands of soldering iron: JBC, Antex, Ewig, Weller (one of the best known).

Workstations where the temperature is adjustable are ideal for making more precise welds on small components (type CMS). A convenient setting for most welds is around 370 ° C. Do not hesitate to test, mainly between 300 ° C and 450 ° C.

Tip: If your soldering iron is too powerful (and connected to the mains directly), you can dose the power through a power dimmer (halogen lamp dimmer type or 230V motor speed controller ). You can make an ultra simple by following this setup:

– Tin

There are two main families of tin: lead-free tin and tin with lead. For realizations, repairs and the vast majority of welds, leaded tin is more convenient to use because of its lower melting point.

Lead-free tin: melting at 230 ° CE with lead: melting at 180 ° C (more practical)

Tin with lead requires less heat, so there is less risk of damaging the tracks of the circuit or the pellets, and also the electronic components. The lead contained in the tin is not found in the fumes when soldering. The fumes are not toxic. On the other hand, they are irritating. If you weld a lot, it is better to use a hood, a fan that extracts air or be outdoors (nice temperature of course …).

Lead-tin is recognized by the Sn60 / Pb40 marking, which means 60% tin (chemical symbol: Sn) and 40% lead (chemical symbol: Pb).

The industry has been using lead-free manufacturing processes for about 10 years for most areas. This allows for RoHS compliance, which means there are no hazardous substances in the circuit board (so no lead in solder). Using lead-free tin lowers the melting point of an existing solder on board and makes working easier (component replacement, connecting something, etc.).

Tip: you can even put a good dose of lead-tin on solder to easily desolder an electronic component!
