What You Should Know About House Electrical Wiring

Home wiring can be on the surface. In that case, the cable is laid on the surface of the wall and held with clips. Or a conduit that passes cables through PVC pipes laid inside the wall. Some trunking PVC pipes are laid on the surface of the wall and the wire passes through. Cables used for surface wiring usually consist of 2 or 3 insulated wires. On the other hand, the cable for conduit wiring is a single-wire insulator so that it can easily pass through the PVC pipe. For cleanliness, conduit wiring is recommended, but a qualified electrician is hired to handle the project and care must be taken to ensure that only high-quality materials are used. This is because a conduit case caused by a failure is usually difficult to track and can lead to a fire.

Insulators, commonly referred to as wires or cables, are composed of various sizes measured in millimeters and are also used to connect various types of electrical fittings. There are also variations of aluminum and copper in the wire. Copper wire is recommended because of the higher resistivity and higher conductor requirements. The following are examples of commonly sized wires and appliances that can be used to connect.

* 1mm-optical switch and socket for electronic equipment
* 1.5mm-bulb and other lighting fixtures
* 2.5mm-air conditioner and refrigerator
* 4mm & 6mm-air conditioner, refrigerator and other large equipment
* 16mm- Used to connect home to public power supply [PHCN].

ELECTRICIAN & # 39; s Dictionary
Switching: This is used to switch between different power sources, for example private power set and public power source. In some cases, you can manually switch to an alternate source in the event of a power outage or failure. There is also an automatic type switch that is configured to switch the power supply automatically.

Circuit breaker: This acts like a fuse and breaks the circuit path when a given amount of current flows. Some breakers are self-resetting, while other breakers require a manual reset. The manual type is highly recommended so that you can monitor the problem when the circuit path is restored.

Control switch: This is also called a load control switch. Installed in home appliances that consume large amounts of power, such as air conditioners and freezers.

Switchgear: In wiring, this refers to the combination of electrical disconnect, fuse, and / or circuit breaker used to isolate electrical equipment. In other words, it is used to cut off power from certain parts of the building so that work can be done to eliminate the obstacles.

Junction Box: This is an electrical connection container that hides the connection from view and prevents damage from unauthorized hands. This forms an integral part of the circuit protection system.

Switch: This is an electrical component that is used to break an electrical circuit, cut off current, or flow from one conductor to another. It is used to control the power flow of the circuit. An example is a light switch.

Lamp holder: This is used for hanging light bulbs and other lighting fixtures. This is usually mounted on a wall or ceiling.

Thunder arresters and earth wires: Thunder arresters are important for controlling the effects of thunderstorms on electrical appliances in that they reduce electromagnetic interference caused by thunderstorms that can cause damage to electrical equipment. The ground wire, on the other hand, is used to ground [connect] the lightning arrester to the ground. It is also used to connect electrical circuits as a standard wiring procedure.
