Electrical Installation

The electrical installation begins from where the electric cable commences on the open road, from which the utility-operated grid delivers power directly to individuals’ houses. A cable then commences to the next electrical cabinet containing the power meter and the main power switch. These are known as circuit breakers. When these two safety measures of safety are in place, the electrical installation is completed. The installation of such a system is entrusted to the experts.


For any electrical installation, there are three major components. First of all, there is the distribution board or board, which is a thin rectangular box with an opening at its top for placing the cable and terminals. This box needs to be near the points where the cables are being distributed. It should be placed at least six inches away from the live wires. The distribution board also has fuses to handle emergencies and the circuit breakers to protect the live wires from the shock caused by overload of electricity.

The fuse is the second major component of an electrical installation. The fuse is a metal cylinder that contains a coil that has the potential to burn up if it comes in contact with combustible material. The fuse box should have a sufficient number of fuses so that the panel may be able to handle the load of current when there is a short or a power outage. The fuse box is usually an insulated box with a central locking mechanism, so that it can be opened only by an authorized person. It is important to ensure that the persons handling the wiring and the fuses are qualified to do so.

Insulation is the third and final component that makes up an electrical installation. The insulating materials come in different varieties and should be selected based on their suitability for the wiring job. The insulation is most useful when it comes to preventing heat transfer. Most people use two types of insulation: the spray foam insulation and the fiberglass.

Wiring of electrical installations should be done according to the power distribution requirements specified by the utility. There are various types of wiring: thermal and voltage. Electrical wiring for power distribution consists of: loads, circuit breakers, transfer switches, wiring to condensers, conduit connections, power distribution lines, outlet strips, fuse holders, and grounding wire.

Fuses, in electrical installation, are devices that are used to turn off electrical systems when they are not in use. They are designed to be very safe and reliable. Fuses should be selected based on their frequency of operation, the expected life span of the fuse, and its electrical resistance. Some Fuses have a higher rating than others and are intended for heavier loads. It is important to ensure that the Fuses are compatible with the electrical wiring systems being installed.

Good electrical installation would avoid the use of electrical equipment that can damage the surrounding materials. Therefore, the fittings and wiring should be made of materials that are durable and will not cause any damages in case they are exposed to fire or electrical shock. The fittings should also be placed at a height so that they cannot come into contact with anything when they are being used. The placement of the Fuses is also very important; the closer they are to the ceiling or other electrical equipment, the better they are.

It is very important that all electrical installations comply with the electrical codes of the United Kingdom and of the North American union. Failure to comply with these codes can lead to major fines. All electrical installations should be inspected periodically for compliance by competent inspectors who specialize in electrical installations.
