Electrical Wiring
Electrical wiring is the network of cabling that delivers electricity to fixtures and appliances throughout a building. It is subject to safety standards for design and installation. Electrical wires and cables are usually insulated with plastic or other material to prevent electrocution. They are also color-coded to indicate their function.
When determining the type of electric wire you need for your project, consider the capacity and voltage requirements of your household appliances. To do this, make a list of your home appliances and calculate their daily usage in terms of watts. Multiply the wattage of each appliance by 1,000 to convert it to kilowatt hours (kWh). This will give you an approximate indication of the gauge of wire that you need.
Household appliances typically require a minimum of 12 or 14-gauge wires to accommodate their electrical demands. Larger appliances may require a higher amperage, which would require a larger wire gauge to handle the load. If you are unsure about what gauge of wire you need for your project, consult an electrician to avoid buying wire that is not suitable for the intended use.
Electrical Troubleshooting
Having trained troubleshooters on-staff saves industrial companies time, money and customer satisfaction. When a piece of equipment goes down, it’s important that maintenance workers know how to quickly identify and resolve the issue in order to keep production running.
Electrical troubleshooting involves a careful inspection of a circuit in search for the source and quickest remedy of any malfunctions. The first step is identifying the problem, which often requires a multistep process that starts with turning off all power to the affected equipment and investigating all of the sources of electricity to the machinery, such as the building’s wiring systems or fuses. Technicians look for visual indications of mechanical damage, such as signs of impact, strained wires and loose components. They also check for evidence of overheating, which can be identified by the smell of burning wires.
It is essential to avoid making assumptions in electrical troubleshooting, as even the most experienced technicians make mistakes. For example, an employee might assume that a dead circuit has been caused by an overload when in reality the circuit could have been tripped by another appliance or even a light bulb. Once the electrical system has been inspected, it’s time to start narrowing down the possible causes of the malfunction using a checklist and basic troubleshooting methods, such as determining what wattage each piece of equipment is drawing from its source.
Electrical Repairs
Modern life is dependent on electrical equipment, but it can break down. An electrical repair technician can troubleshoot a piece of malfunctioning equipment and fix it to keep it running.
Often times when an automobile shows signs of electrical issues such as the inability to start it, the reason is a bad battery, alternator or starter. An auto electrical repair technician will inspect all of these components and determine the best solution to rectify the problem.
If there is a corrosion build-up on the terminal ends of the battery, a chemical terminal cleaner will be used to remove it and clean it off. Then the battery will be tested and reconditioned to ensure that it is in good condition and capable of holding a charge.
When it comes to home electric repairs, it is always best to leave them to the professionals. Electrical issues are responsible for causing thousands of home fires each year and can result in damage to your belongings or serious injury to a family member. Open junction boxes and uncovered light or dimmer switches are also a huge safety hazard, as they can allow children to experiment with the outlet and cause an electric shock. An electrician can replace and install covers and switches, as well as repair or replace lamps. He or she can also connect approved portable electrical equipment to the appropriate permanent receptacles.
Electrical Installations
Electrical installations connect and power multiple items of electrical equipment within a building. They combine and permanently connect equipment from a local electricity supply and deliver power to the equipment’s control and distribution devices. Electrical installations are subject to strict safety standards to protect people from injury and property damage. These standards vary by location, country, and region.
Residential wiring systems are subject to a standard, or code, set by the national or regional electrical authority. Wiring codes may also vary by locality within a country. The International Electrotechnical Commission tries to standardize wiring regulations, but significant variations still exist between different countries.
Many residential electrical projects require the services of a certified electrician. Whether you are adding outlets to your spare bedroom or installing a new appliance, you need professional help to ensure the work is done correctly.
Industrial electrical installations are critical for the productivity and operations of factories and other industrial facilities. These electrical systems power machinery and lighting, as well as support communication systems. They must be designed, installed, and maintained to adhere to strict safety standards.
