Numerous Best Quality Electrical wires Cables are used at the domestic level to transport electricity from the main panel to different home appliances. However, it is of paramount significance to know about the basic knowledge of these wires, and only then the accurate choice can be made in the selection of wires and cable from the Best Electrician point of view. Electricity has greatly helped us in achieving our modern goals of today as without electricity it is not possible at all. The need for this resource is rising for a long time and electrical wires transport this electricity to our homes which are generated somewhere at power plants. Wires are an essential part of the house as these help in connecting the equipment in the house. We must be very careful while dealing with electricity and at the same time we should always use high-quality wires in the house. Poor quality wire can easily get heated and in this case, chances of fire hazard multiply. Using poor-quality wires can also increase the chances of electric shock.
Tips to Consider While Selecting Quality Wires and Cables
When it becomes necessary to select a cable or wire, the following factors must be given special consideration.
Brand – Branded and well-reputed wires must be purchased only. Always remember that using poor-quality cables and wires will always be a risk for you and your family. Not only human being is at risk but also our home appliances face the same danger. Therefore, only reputed brands of top-quality wires to be selected.
Gauge and rating – Wires are available in the market in different sizes and gauges. Such size and gauge meant carrying safely a specific amount of electric current. One available gauge or size of wire can be fit for carrying one voltage while the same wire is unsafe for transporting another amount of voltage. For example, a 1000-watt electric heater requires high gauge wire, and using a low gauge cable might heat up and chances of short circuit or electric fire are there.
Coating – Well reputed brand wires and cable available with high protection principles. The protection here means the coating that surrounds the wires. The said coating is meant to prevent short circuits and keep us safe from being electrocuted. Although all the electric wires produced with a coating, however, the quality of the coating always remains a matter for the users.
Type of wire or cable – Countless varieties of wires and cables are available in the market, however, an individual requirement of users at home is varied. Until and unless a specific requirement is not comprehended, an exact selection cannot be made. In the market, the difference of wire is based on the gauge for wires and the number of cores within it. To find out your requirement first and then purchase accordingly. Purchasing a wire or cable is easy if one considers all the factors mentioned above.
What the Color Scheme of an Electrical Wire Signify?
Remember that all the wires carry an electrical current at varied points, that is why treat every color wire with equal caution. If you have any hesitations at all, leave the electricity job at once until the arrival of a professional.
Black Color Electrical Wires/ Cables
This said wire is used to carry power to miscellaneous switches and in all types of circuits. Black wires are also used as switch legs in circuits, which link a switch to the electrical load. Make sure to be vigilant that all black wires are live at all times.
Red Electrical Wires/ Cables
In all circuits, red wires are the secondary live wires. Like black wires, they can also be used in some types of switch legs. In addition, red wires are used to connect smoke detectors. It is possible to link two red wires together or a red wire to a black wire.
Blue Electrical Wires/ Cables
While wires in these colors carry power, they are not used in typical outlet wiring. Instead, blue wires are used as the live wire. For example, you may see yellow wires as switch legs to ceiling fans and other outlets paired with light switches. These are also used as travelers for three- or four-way switches.
White and Gray Electrical Wires/Cables
White is most commonly used, but gray wires also serve the same function. They serve as a neutral wire to connect to the neutral bus bar, within an electrical panel that attracts the electric current for distribution throughout the house. These electrical wires can only be connected. Although they are called “neutral” wires, however, they may still carry a current, especially if the current load in the circuit is unbalanced. Therefore, careful handling of these wires is preferably needed to avoid untoward occurrences.
Green Electrical Wires/ Cables
Green wire aims to ground an electrical circuit. They connect to the grounding terminal and run the ground bus bar in an electrical panel. In this way, green wires act as a safety device and giving electricity room to escape into the ground if there is a live wire within the circuit that touches metal or something else. It is to be remembered that Green wires can only connect to other green wires. Keep in mind that if there is a fault somewhere in the circuit, green wires can be live, so pay special heed.
Best Quality Electrical Wire Cables Other perspectives
Other perspectives of electrical cable are also to be kept in mind while selecting the right cables. As cables measure voltage so they are categorized into the following groups:
• Low Voltage cables: The said group of cables are designed and built to carry up to 750 voltages of current. This group of cables is used for industrial power installations in varied fields and carries up to 1000 v.
• Medium Voltage cables: These are used to distribute electricity from substations to transformer stations and the voltage range is from 1 kV to 36 kV.
• High Voltage cables: from 36 kV. The said of cables is used to carry electricity from Power generation house to the substations while voltage range from 36 kV and above.
Types of Electric Conductors
• Bare wire conductor: These are single-wire available in solid-state and without coating.
• Aluminum conductors: Aluminum conductors are also used as a conductor although the said metal is 60% bad conductor than copper.
• Copper Conductors: It is the most widely used material because it is a good conductor of electricity.
• Single Core Cable: It is a cable available with a single conductor.
• Multi-Core Cable: The said cable has several conductors within the insulation cover.
Classes of Insulation for Best Quality Electrical Wire Cables
The purpose of insulating coating on the conductor is to prevent current leakage from it. They are classed into two main groups i.e. thermoplastic insulation and thermosetting insulation.
a. Thermoplastic Insulation
They are most common in the following shapes.
• PVC: Polyvinyl chloride
• Z1: Polyolefin
• PE: Linear polyethylene
• PU: Polyurethane
b. Thermosetting Insulation
The most common are shapes are as follow:
• EPR: Ethylene Propylene
• XLPE: Cross-linked Polyethylene
• EVA: Ethyl Vinyl Acetate
• SI: Silicone
