Electrical materials used in house wiring, I believe these are the materials that you need to wire your house from start to finish. I personally have done a lot of electrical house wiring including commercial and industrial buildings. For this reason, I will share with you materials that are commonly used. First I will list down the materials and later I will explain how each material is used.
List of electrical materials used in house wiring.
- Conduit pipes.
- Couplings/Female bushes
- Adapters/Male bushes
- Junction boxes/Loop inboxes
- Switch boxes
- Sockets boxes
- Cooker control boxes
- Distribution board/Consumer unit
- Meter box
- Circuit breakers
- Cooker control
- Geyser switch
- Light fixtures.
- Roof shackle.
Conduit pipes are the basic materials that you will need to wire your house. Conduit pipes can either be PVC or GI galvanised. These conduits can be flexible as well. What is the work of conduit pipes? Conduit pipes are mainly used to create a passage through which cables are run. Conduit pipes protect the cables from being damaged. If you are doing your house wiring and you want it to stand a test of time run your cables through the conduit pipe.
Couplings and adapters.
These two electrical wiring accessories are very important, materials in electrical house wiring. These are the accessories that make tubing works very easy. What is the main function of these two accessories? The coupling or female bush is mainly used to join two conduit pipes. While the adapter or male bush is mainly used to join a conduit pipe and either a switch box, loop inbox and junction box.
These are pre-made bends or elbows. You use already made bends when you don’t have a spring bender to bend the conduit pipes. Bends are mainly used to join conduit pipes at a point where you want to bend your conduit pipe.
Junction boxes/Loop inboxes.
Junction boxes and loop inboxes have three main functions. The first you use junction boxes at a point where you want to join your cables. In the second situation, you use a loop inbox at the point where you want to mount your light fixture. Thirdly you use either a loop inbox or junction box when you want to split the path through which you will run your cable or joining two or more circuits.
Sockets and switch boxes.
Just from their name, you can tell that these are the boxes where you mount or instal your switches and sockets. I feel I should mention here that both sockets and switch boxes can either be flush or surface mounted. You use flush-mounted boxes when you embed or conceal your conduit pipes in walls. Then you use surface-mounted boxes when you install your conduits on the surface of the walls.
Cooker control boxes.
Cooker control boxes are installed on positions where you would like to control your cooker. Usually, it should not be far from the actual cooker unit. These boxes come in various sizes. The choice of size mainly is left to the owner.
Distribution board/Consumer unit
The heart of your electrical house wiring. Why do I say so? all your electrical circuits in the house come from the distribution box. Distribution boxes can either be surface or flush-mounted. This is dependent on the type of wiring that you decide to use. All the circuit breakers controlling your lighting and power circuits are installed in the distribution board.
This is a box where the service cable from your electricity utility company connects power to your house via the distribution board. It is in this box you install your lightning arrester and incomer circuit breaker.
The MCB is the most used circuit breaker in homes. A circuit breaker is an electrical device that is used to control a circuit. in the home. A circuit breaker can detect an overload in the circuit it controls. It does not only detect an overload but a short circuit as well. In both cases, a circuit will trip automatically thereby protecting your house and installed electrical appliances.
Cables are conductors through which electricity passes through.There a lot of cable available but for the purpose of electrical house wiring.I will limit my discussion to cables that are used in house wiring.
In electrical house wiring, you use cable types and sizes with the circuit that you wish to wire.I will talk about lighting, power or sockets, incomer, cooker and geyser circuits
LIGHTING. In the lighting circuit, you use 1.5mm squared cables. The circuit should have three cables red black and green. Red for live, Black for neutral and Green for the earth. I know some countries have different colour code. Find out from a qualified electrician or technician the correct colour code in your area.
POWER/SOCKETS.In power circuits a 2.5mm squared cable is used.The colour code is the same as in the lighting circuit.
INCOMER/SERVICE CABLE. The incomer or service cable should be the biggest cable size in your home. As the correct size of the service cable, this is different from country to country. For those using the British standard, some time back 16mm squared cables was used as the service cable. Nowadays, most utility companies use 10mm squared cable for the service cable.
COOKER AND GEYSER.use 6mm squared cable for the cooker and 4mm squared cable for the geyser. Both of these appliances must be earthed. Therefore, you run three cables. For the live neutral and earth. The colour code is the same as in lighting.
Sockets and switches.
Sockets come in various forms but the most common types are the double and single sockets.You use socket outlets to power electrical and electronics appliance in the home.Good examples of appliances powered through sockets outlets are Television,laptop,refrigerator,and a charger for your mobile phone..
Switches also come in many forms. The widely used switches are photocells, one-way switch, two-way switch and intermediate switch. A photocell is used when you want your outdoor lights to light automatically.
One way switch is used to control a light fixture from one position. A two-way switch is used when you want to switch light from two positions. You use an intermediate switch when you want to control a light point from three positions.
I for one I think that light fixture make our homes to look nice and good. Naturally, light fixtures give the feel and mood of a room. You can achieve any mood that you want when you combine all the available light fitting in a certain way. Let me mention that there are a lot of light fittings. I will list the most widely used fittings.
List of common light fittings.
- Pendant lights
- Led lights
- Fluorescent light
- Floor lamps
The above list is not an exhaustive list.
Roof shacke is an electrical accessory that is used to anchor the service cable to your house. This applies when you are supplied power through overhead.
