House Wiring

Electricity is supplied to your home by wires buried above or below your utility. Before entering your home, electricity is passed through a watt-hour meter and the amount of electricity used has measured.

It then enters your home via a service access panel (also known as a “loading center”), where circuit breakers or fuses have located.

Electricity distributes throughout your home using branch circuits to supply power to appliances and lamps through pots, switches and fixtures.

 Types of electrical housing wiring systems

Cleat wire

These cables consist of PVC insulated wire or ordinary VIR. They have placed on the walls and ceilings using branches, wood or plastic using porcelain cleats. It is not suitable for indoor premises as it is a temporary wiring system. Also, the cleat cable system is rarely used these days.

Covers and shielded cables

It was very popular in the past, but nowadays it is considered obsolete due to the popularity of carrier and sheet cable systems. The cables used in these power lines were PVC, VIR or other approved insulated cables. The cables were routed through wooden casing boxes and covered with a wooden strip with parallel grooves cut lengthwise to secure the cables.

Baton wiring

This is done by placing a single electric wire or group of wires on a wooden tube. Using a wire brass strap, place the batten on a pole at a distance of 10 cm for horizontal running and 15 cm for vertical running.

Lead sheet wire

The conductors used in the lead sheet wires are insulated with VIR. And it covered with an outer sheath of lead-aluminum alloy, which contains about 95% lead. The metal sheath protects the cables from mechanical damage, moisture and atmospheric corrosion.

Conduit Wiring

There are two types of carrier cables depending on the pipe installation:

When GI or PVC conductors are installed on the surface conductor cable walls or roof, it is called surface conductor wiring. The conductors are mounted to the walls with a 2-hole strap and a base strap at regular intervals. The electrical wires are placed in the conductors.

When hidden conductor wires are hidden in the wall shelf or in the brick wall it is called concealed conductor wires. The electrical wires are placed in the conductors. This is more popular because it is stronger and more aesthetically appealing.
