Electrical Installation Training To Learn Electrical Skills


Electrical hazards can cause burns, shocks, and electrocution (death). The image above shows multiple National Electric Code (NEC) violations and poor workmanship making it a clear electrical fail. We have listed the specific NEC violations at the end of this post for you to review

Although these are simple issues to repair, and everything in this photo could be fixed for a few hundred dollars, that is not an accurate representation of what the cost would be if these issues were not found in time and caused the electrical system to fail

The true electrical fail in this photo is the person who performed this electrical installation. The photo clearly shows that the person performing the installation didn’t have a true understanding of the National Electric Code or didn’t care about the safety risk they were creating. Violating the National Electric Code and delivering poor workmanship can create a dangerous electrical hazard for the facility as well as other electricians following behind. If these issues were not found and repaired by a licensed electrician, they would have led to shorting and arcing which can cause electrical fires or shock and lead to an extremely high repair cost and OSHA fines all while compromising the safety of employees.

Choosing and using an electrician

For all our celebrated national love of DIY, when it comes to tackling the electrics, most of us are wise enough to call in the professionals. According to the Electrical Contractor’s Association (ECA), a recent report showed that almost three-quarters of homeowners would not attempt electrical jobs themselves, which means there’s a lot of work out there for a skilled electrician.

Unfortunately there are also a lot of lucrative opportunities for unscrupulous unskilled electricians as well. Incredibly, there is no statutory requirement for electrical contractors to be qualified, so you need to make very sure that you choose someone who is not going to leave you living in a time bomb. As the National Inspection Council for Electrical Installation Contracting (NICEIC) points out, “It’s easy to make an electrical circuit work – it’s far more demanding to make the circuit work safely.”

If you’re having electrical work done, it’s often going to be part of general building work, in which case your chosen builder will probably have a favourite contractor. The Federation of Master Builders (FMB), which has a rigorous vetting procedure and a useful website recommends you take your builder’s advice, as long as you’re generally happy with their credentials.

Electrical installation design methodology

Range of low-voltage extends from 0 V to 1 000 V in a.c. and from 0 V to 1 500V in d.c. One of the first decision is the selection of type of current between the alternative current which corresponds to the most common type of current through out the world and the direct current. Then designers have to select the most appropriate rated voltage within these ranges of voltages. When connected to a LV public network, the type of current and the rated voltage are already selected and imposed by the Utility.

Compliance with national regulations is then the second priority of the designers of electrical installation. Regulations may be based on national or international standards such as the IEC 60364 series.

Selection of equipment complying with national or international product standards and appropriate verification of the completed installation is a powerful mean for providing a safe installation with the expected quality. Defining and complying with the verification and testing of the electrical installation at its completion as well as periodic time will guarantee the safety and the quality of this installation all along its life cycle. Conformity of equipment according to the appropriate product standards used within the installation is also of prime importance for the level of safety and quality.

A review of all applications needing to be supplied with electricity is to be done. Any possible extensions or modifications during the whole life of the electrical installation are to be considered. Such a review aimed to estimate the current flowing in each circuit of the installation and the power supplies needed.

The total current or power demand can be calculated from the data relative to the location and power of each load, together with the knowledge of the operating modes(steady state demand, starting conditions, non simultaneous operation, etc.)

How electricians choose the most suitable protection devices

There are at least four main issues electricians must take care off very carefully when choosing the most suitable protection devices. Of course, there are dozen of other issues, but let’s try to define the most important ones from the aspect of protection: short circuits, overloads, earth faults and surges.

Shorts circuits

This is certainly one of the most tricky issues for electricians designing electrical installations. For this purpose, he must ensure good co-ordination of protection devices

To increase availability of a feeder, we recommend that you supply it as far upstream as possible (near the source) to prevent tripping a protection device for another item of equipment.

On networks with high availability, use of an automatic resetting device may be justified if discrimination is partial or if a short circuit can be eliminated naturally (this is rare). This technique is used in high voltage but seldom in low voltage: a rodent or crawling animal causing a fault leads in most cases to a permanent short circuit fault.


The overload current is seen by the circuit breakers upstream of the faulty load. To prevent tripping of these protection devices

Cables and wires

Cable and wires make the transfer of electrical signals possible. Extensive range of cables and wires make them suitable for all types of application. There are installation wires, control cables, power cables, medium and high voltage cables and many more.


Every house or garden needs good lighting. Thanks to wide range of lighting every customer can choose the best product with suitable colour or shape. Among modern lighting there are classic lamps or very ornamental whereas modern light bulbs are energy-saving and durable.

Electrical installation equipment

Electrical installation equipment – switches, dimmers, sockets – is a very important part of the house’s design. It should be functional but also aesthetic. It is manufactured from various materials, for example metal, glass or wood

Modular apparatus and automation

Modular apparatus protects electrical installations in buildings from for example overvoltage. It can also control and measure. The elements of automation such as controllers or sensors are used in industry and construction sectors where there is need to make processes autimatic.
