The Electrical cables wiring system could be as easy as following the given tips. Connect the cords, the circuit connections, the device connections, the electrical board connections. These all need some kind of cabling connections. Here are the electrical cables wiring tips:

1. The Appliance electrical Wiring:

Every piece of equipment, if it is a counter top electrical device like a pot of coffee or a main electrical device such as an electric range, which has the electrical connection, all of these have particular channel and definite breaker range that they are necessary to be connected.

2. The Electrical cable Wiring Connection – Either Good or Bad:

The manufacturers although providing the option of special points of connection, such as with the switches and the outlets, but a close look would disclose that which type of connection must be opted. There are some connections of electrical cables which should not be used however.

3. The Electrical Services Wiring:

To make the appropriate links to the components of electrical services would help to keep the electricity leakage. Before connecting the wire to the electric meter, to disconnect, the electrical panel, and the sub-panels, or anything related to connection make sure that the procedure you know very well.

4. The Electrical appliance Wiring:

The Electrical appliances should be wired to build the electrical connections secure and protected. There are some appliances that need the outlets of just 120-volts; however the others require the outlets of 240-volts. It is not enough to connect the wires to device terminals. The appropriate way is needed to strip, to bend and make tighter the connections in order to get the useful connection.

5. Wiring Size and Application:

It must be remembered that which electrical cable to use for installation before making electrical connections. The color of the wire is also important for electrical application, similarly the suitable size of wire also to manage the weight of the circuit. But For the electricians and the technicians, the colors of the wires mean not anything specific. They categorize the wires that whether the cables are hot, ground wire or just neutral.

  1. 1.      The Materials of electrical Wires – The Aluminum and the copper are usually used materials for manufacturing the electric wires. The Copper is thought to be the perfect material for making the electrical wires due to its greater conductivity, the superior ductility, the greatest potency and prevention to oxidization.

    2. The Size of the electrical cables
     – The Electrical cables might be formed in different sizes. The magnitude of the electrical cables would differ with the needs of the working voltage, the power and the temperature. If the size of the size of the electrical wire would be higher then the need for the power, the voltage and the temperature would be higher.


3. The Types of the Insulation
 – The function of the insulation is to stop the outflow of the current, and save the conducting cables from external elements and the surrounding. The Insulation wires separate the conductor from each other mot only physically but electrically as well. The insulating materials that are normally used are the PVC, the Polypropylene, and the Polyethylene.

Sizes of Electrical Cables Used in Residential Projects

Electrical cables are the main source to supply power to the wiring and equipment used at home. There are different types, sizes and strength of cables which are used according to the requirement. These cables has different sizes according to the kind of circuit for which they are used. If the gauge is lower than the wire will be thicker. Gauge wiring which is larger is used for heavy applications so it can take the flow of current without getting short or overheated. That is why it is very important to have the knowledge of law and appropriate safety measurements to take when one is installing electrical cables.  Before starting any project regarding wiring, it is important to obtain permits and conduct proper inspections of the area. Also it is wise ti contact a wiring man or skilled electrician to do the project. Following are the list of cable sizes which are used in residential wiring.

 

NM-B Electrical Cable

This type of cable contains at least 2 individually insulated wires. These wires are then housed together in a non metallic PVC or nylon made flexible sheath. NM is reference to non-metallic sheath while B indicates the insulation around the 2 wires. It is made to handle current heat of maximum 90 Celsius degrees.

 

14-2 Gauge Cable

It is used for circuits which requires 15 amps or less. 14-2 gauge cable is mostly utilized in installation of items like switches on walls, receptacles, lighting fixture and power outlets. This cable is also consist of 2 individual wires, 14 gauge each. This gauge measurement shows the amount of electric current the wire can conduct.

 

14-3 Gauge Cable

It is also used in those circuits which require up to 15 amps and are common in the wiring for switches of 3 way light, ceiling fans and receptacles which are split.

 

12-2 Gauge Cable

It is used for the appliances which require up to 20 amps. These appliance can be furnaces, air conditioners, water heaters, dishwashers, kitchen receptacles and freezers.

 

12-3 Gauge Cable

It is also used for the wiring of standard appliances which require 20 amps or lesser.

 

10-3/8-3 Gauge Cable

This size of wiring cable is used in the installation of electrical items which require more than 30 amps. It is used for electric dryers and ranges.

 

All these sizes are used in the electrical project according to the requirement of equipment, circuit and power supply. Only a skilled electrical, a wiring expert or the person dealing in electrical cables can tell accurately that which size is appropriate for which requirement. That is why, it is a wise thing to consult them before purchasing the cables for your project so they can guide you properly about the details of wiring. It is not only safe but also a money saving action to take the guidance from experts instead of doing the work your self if you are not expert because electrical things are not safe to handle without proper precaution and appropriate guidance.

Electrical Cables

The term ‘Electrical Cable’ is generally used to describe insulated conductors that carries electricity. The basic function of electrical cables is this that they conduct electricity from its source to some piece of equipment or tool such as computer, television, microwave etc. the composition of electrical cables is not that much difficult. Electrical cables are made up of metals that can conduct electricity, such as copper, aluminum etc. Electrical cables that are manufactured today are usually made up of copper due to its high electrical conductivity and flexibility. Small cables are stranded to produce electrical cables that are more flexible. This process requires small individual wires to be twisted or tangled together to produce large more flexible cables so that the working of those cables could be made more efficient. Copper is often plated with a thin layer of some other material such as gold, silver or tin as these materials are less prone to oxidation as compared to copper. This makes the electrical cables long lasting and more durable and also helps in reducing the chances of getting short circuit. If copper is a not available, then in such case, electrical cable can also be manufactured by using aluminum or copper plated aluminum as they can also serve the same purpose as will gold, silver or tin will do.

           Electrical cables of both, copper and aluminum are vital in the production of many equipments and infrastructure. These cables have a significant use in the fields of construction, shipbuilding, mining, aeronautics, energy, machinery etc. Thus due to their demand and importance electrical cables are manufactured under strict international standards.

Cables used for industrial and commercial purposes contain insulated conductors in order to protect them from moisture, which can cause physical damage to them. Cables manufactured for marine or some other very flexible services are shielded with woven a bronze wire that protects them. Power or communications cables, routed in or through air-handling spaces of office buildings must be encased in metal conduit and rated for low flame and smoke production to make sure they are safe.

In building construction it is important to make sure that that electrical cable used in the wiring are coated with a material that is fire resistant. Inorganic coating safeguards the adjacent areas from the risk of fire spreading and causing damage to both life and property. A cable can be made safe from the risk of spreading fire by either adding insulating material with fire resistant materials or by covering the copper conductor with mineral insulation.

One problem with electrical cables carrying current is that they radiate electromagnetic field. This electromagnetic field can be picked up by any conductor or cable; this unwanted transmission of energy can cause damage to the equipment. This problem can however be avoided by  keeping the length of the cables in buildings short as transmission and pick up are proportional to the cable’s length. Also some particular cable designs such as shielding, coaxial and twisted pair can be used to avoid such problems.

Colors of Electric Cables Matter

Each wire has different color and has its purpose. Electric cables installation will be easier if you have some knowledge of letters and colors of wires. If you want the electrical appliances and power system to function smoothly and safely, the installation needed to be done correctly by the professionals for the best performance.

Black cables and red cables are used to utilize as hot wires. They’re often used for switch legs such as in the ceiling fans and maybe fed to an outlet or switch but never use them in neutral or ground connections.

Moreover, other hot wires can be colored in blue and yellow. Normally they have switches with 3-4 ways applications. Fans, lights switches also have legs in blue cables but yellow cables normally are used as switch legs for controlling units. For grounding installations, the green cables are usually used for that purpose. So that it will be connected to grounding unites and devices for safety of appliances. Underground cable is subject to ensure the safety which can lead to damage and the worst can happen is the effect to people which can cause a death. White cables are used as hot wires also or with 240 volts appliances. It can also be used as switch leg in 3 way switch and lighting fixture.

It is really important to make sure that each of electric cables is in shape of great use. Be careful and make sure that the cables are installed well and correctly because they can develop problems and I know that you don’t want to waste your time and money fixing it up over again. If everything is okay, the power will run smoothly and efficiency. But if there are something happening with the cables and you’re not sure what to do, just call the professionals to help you out.

How to install electric cables

Electric cables installation is a necessity for providing the power in our home for operating heat and appliance using. It is usually done by professionals for safety. But some basics about electrical and wiring installation will be useful for us to know also in case we need to electric cables repairs in our home. And here are the basic principles on how to install the cables briefly.

1.  Shut down the main power supply

Before doing anything, shut down the main power supply to prevent dangerous situations that may occur. This is very important. Or you can just choose to shut down specific circuit if you just need to work on specific area.

2.  Studying the guide book

Reading the how-to book or guide book will help you understand the electric cables in your home more. Normally, the guide books will be explained with pictures which are easily understandable. The manual should be kept at home where you can easily find. It will be very helpful in case there’re unexpected electrical problems happening.

3.   Colors of the wires

Each wire has color and it is color coded to prevent wiring errors. Please note that the same colored wires connect to each other. Black wires are used for connecting switches and white wires are intended to connect with other white wires. But in some cases if this is the material, white wires are used instead of black wires but for the easy separation, painting white wire black will be helpful but just keep in mind that each color is intended to be used differently, don’t get confused.

Here are the basics to help you understanding and knowing how the electric cables are installed. However, if you’re unsure about your ability to fix up or change the electric cables, it is best and recommended to leave it to the professionals.

 

Selecting electric cables for your own usage

There are over thousands electric cables available in the market. Before purchasing cable or wire, you should have the right knowledge and information of each wire. There are several things you should consider before buying wire or cable. Knowing the basic can help you make a decision better as you know that each company has a variety of products and we can’t really know what is good and bad.

Cable shielding is used to ensure the smooth of electrical process. It helps the power runs smoothly and lessens the problems of signal exit and entrance caused by interference in the electric cables. There are many types of shield such as braid, spiral, foil, and braid/foil shield. To select the right one for your using, it’s best to do research on each type of shielding before buying electric cables.

Temperature range is also what to consider before purchasing cables or wires. Make sure a cable can handle the temperatures in the highest range of your appliances and also the temperatures of the Mother Nature in the worst case scenario. You don’t want to change the cables in your house often, right? In addition, choosing the high quality electric cables that are flexible will make the installation and fixing much easier.

Due to the fact that electric cables possess several levels of chemical resistance, you should keep in mind that some kinds of chemicals can cause troubles in the entire lifespan of your wire. Additional sealing can prevent moisture permeation and help the cables last longer.

However, it is hard to select the ideal electric cables if you lack of knowledge. Above is just basic knowledge you should know. If you want to learn and know more of each type of cable and how to use it, it is recommended to ask and discuss with the electrical professionals or the manufacturer and distributor.

High voltage.

What is high voltage.

ACSR

High Voltage is the electrical voltage between the power lines exceeding 1000 volts or more.

Why use high voltage

Power system with high voltage electricity can be sent to a distance. And the loss of electrical power system under a low voltage. The power transmission efficiency. Must be delivered with high voltage almost all

High voltage is dangerous, however.

Because high voltage is the voltage very high compared with the low voltage. With common household appliances (220 volts), high voltage is able to jump over the air. Or insulators have approached the object or creature. Without touching or touching wires. If the object is within a high voltage dangers that can jump over it. This will depend on the risk level of the voltage of the high voltage By the high-voltage electricity can jump across the stage, it is extremely remote. High voltage is dangerous genie. The statistics have been danger of high voltage in the service of the MEA. Deaths per year, nearly 100 injured and disabled people.

We do know that it is a high-voltage power lines.

Due to high voltage power lines is dangerous to jump over, so they have to hold the power cord. With an insulating material. To some extent with the high voltage. Insulators used mainly to do with ceramic floors. Hand shaped like an inverted bowl called insulators. Therefore, we can observe that the high voltage power lines. From the power line insulators with layers. The Class of insulators. To indicate the voltage level of the high voltage. Observing that the high voltage Another is. The height of the power cord. High voltage power lines. Usually elevation of 9 meters above the ground from the power lines above. Usually the voltage over the power lines below.

High voltage power lines are insulated or not.

High voltage power lines, most of the electricity used by road or field. Most are not insulated, or if there is insulated cover only some of which are considered unsafe to touch or touch. Insulation shall be secured with thick insulation. Are overlain by a thousand Shield (Shield) and a shell on top. The cable is heavy so it can not lean on the power poles are not.

Knowing the types of electrical cables

Cable-Types

To know the types of electrical cables can help you choose and use the right wire for your application at home as there’re various types and prices of wire and cable in the market. It is very important to use and keep any type of cables safely to prevent us from unpredictable danger that may happen at times.

Aluminum Wiring

It is the cheapest and most dangerous wiring that is still being used because it’s easy to bend and shape. But most people don’t know that this kind of wire has the lowest quality and can cause a fire in your home if it gets damage or becomes overheated. Aluminum wire is cheap and easy to find but is not recommended to be used if you care about danger.

Copper Wiring

When it comes to good quality electrical cables, this one is standard material that many electrical contractors choose to work with. It is a little bit expensive due to the performance of itself but it’s still a good choice for people who care about danger that may have caused by electrical cables in your house. Most of time, it’s used for underground purposes, for example, connecting of wire ways, channels, tracks and conduits to guarantee the safety of the underground. Moreover, the copper wiring can also be used for poor ventilation area.

Silver Wiring

This one has the highest quality with very expensive prices which is rarely used because it is harder to bend and shape.

However, the materials of the electrical cables are what we should pay attention about as well. Each of wiring, even though how expensive it is, cannot be 100% trusted as we all know that electricity is dangerous and can easily cause massive troubles so it’s best to ask or consult with a professional to ensure the safety and to understand all of the electrical cables more.
