What Does an Electrician Do?

Electrician West Chester PA works to install, repair, and maintain electrical systems. They execute the plans of electrical engineers and may work as part of a construction team or independently.Electrician

Most electricians complete a trade school program that includes 144 hours of technical training and 2,000 hours of on-the-job experience. They then take and pass a licensure exam.

Electricians install and repair electrical wiring and fixtures in structures like homes, office buildings, retail shops, and industrial factories. They follow blueprints and technical drawings to wire new construction or update existing systems. Their responsibilities also include testing equipment and ensuring that all components comply with safety standards.

An electrician can specialize in different areas depending on their skills and experience. Some are skilled at working on residential or commercial structures, while others may work specifically on power transmission lines. The specialized work of these electricians helps ensure that electricity reaches the people and places that need it most.

During the installation process, an electrician follows all necessary precautions to prevent fires or other accidents. This can involve removing old wiring, rewiring or replacing it with newer models, and resetting breakers. It is essential for these professionals to be familiar with all local building codes and safety regulations.

Other responsibilities of an electrician involve inspecting and maintaining the wiring, fixtures, and other equipment that make up a power grid. This can involve working on electrical stations and substations as well as repairing any problems that occur during distribution. The responsibilities of these professionals often include climbing poles or using lift buckets to reach high areas to inspect and repair electrical equipment. They are also responsible for maintaining grounding systems and installing protective devices like circuit breakers and surge protectors.


If a fixture or an appliance starts acting weird or giving out sparks, it’s time to call in the professionals. Trying to fix faulty electrical fixtures on your own can lead to serious injuries or even fatalities.

The first thing that an electrician does is gather as much information as they can about the malfunctioning fixture or appliance. This includes the owner’s manual and other technical documentation that can help them troubleshoot more effectively.

Once the electrician has this information, they’ll try to determine which component or part is causing the problem. They’ll do this by isolating each component or part according to the parameters that they’ve determined. Then they’ll examine each one by measuring the input and output signals that they send or receive.

Once they’ve found the culprit, they’ll either repair it or replace it. After that, they’ll repeat the steps above to make sure that everything’s working properly again. This is an important step because it ensures that they’ve taken care of the problem completely and that it won’t happen again in the future. It also helps them save time by not having to go back through the troubleshooting process again and again. This is especially helpful if they’re working on a large electrical project.


Electrical maintenance is the process of inspecting, testing, and monitoring equipment to ensure that it’s working properly. This is important for residential and commercial properties because it prevents problems that can cause a loss of power or an electrical fire. It also helps reduce costs by avoiding the need for expensive repairs or replacements.

Some electricians specialize in specific types of maintenance. For example, a residential electrician may focus on installing wiring, outlets, and switches in homes and apartment buildings. These electricians also perform maintenance on electrical systems and appliances in these buildings. In addition, they are responsible for ensuring compliance with residential electrical codes and safety standards.

Another type of electrical maintenance is performed by electricians who specialize in maintaining and repairing industrial equipment. This includes electrical systems in factories, warehouses, and other large industrial facilities. These electricians must be able to read and understand blueprints and use a variety of hand and power tools to maintain equipment. They also need to have excellent customer service skills so they can communicate effectively with other employees and management personnel.

Preventive maintenance is a vital part of any business, and it’s no different for electrical systems. Many electricians perform this type of maintenance by regularly checking for signs of wear and tear and repairing them before they become more serious problems. They may also replace worn parts or make upgrades to improve energy efficiency.

Electrical maintenance is especially critical for businesses that rely on heavy machinery or sensitive electronic devices, such as hospitals and private practices. These types of electrical systems require regular maintenance to ensure the health and safety of patients and staff. Without maintenance, electrical short circuits can cause fires or other problems that could endanger lives.


Electrical testers are used to check whether a product, component, or installation can be safely energized. Tests are usually carried out on the basis of pre-determined regulations (such as those in Guidance Note GS 38). The types of tests that can be performed depend on the type of equipment and circuits being tested, but can include:

RCD testing: checks to ensure residual current devices shut off electric current quickly when they detect imbalances to reduce the risk of shock or fire. Tests may also include a visual inspection of the wiring.

Insulation resistance tests, sometimes known as “meggering,” put the electric insulation of an installation or product under a voltage much higher than its operating voltage to see how it holds up. These tests can reveal faulty or damaged insulation that needs repair.

Continuity and earth continuity tests can be used to determine if metal parts of an installation are connected to the correct points on a system or not. These tests often involve a digital multimeter and a visual inspection of the installation.

A low-resistance ohmmeter is often used to test switches, circuits, and bonds for contact resistance. This type of test can be done without dismantling the switch or disconnecting the circuit. It can identify a number of problems, including corroded connections and poor contact between surfaces.

For safety reasons, it’s important for electricians to wear gloves and full protective clothing when performing electrical tests. They must also leave bulky or loose items, such as food and drinks, outside the testing area so they don’t interfere with the test results. Basic classroom courses can help an electrician develop the skills they need to work safely.


When a piece of electrical equipment breaks down, the first thing an electrician must do is determine what caused it to stop working. This involves a systematic process of observing the device and its components in order to find the root cause. The electrician may also need to consult technical documentation on the equipment or seek help from a colleague who has worked with it before.

Using this information, the next step in troubleshooting procedures is to identify what components need to be evaluated. This might involve isolating circuits per group or evaluating the circuit parameters of each component. This step is especially important since some electrical devices are very complex and might have multiple components that are prone to malfunction.

Once the problem is identified, the electrician can begin to work on it. They may need to inspect the circuit to check for mechanical indications of damage, such as broken fuses, loose wires, and signs of overheating. They must be careful not to touch energized wires or circuits, so they should shut off the power before beginning work. They should also be sure to tag the circuit so that others know not to work on it.

This is a challenging but rewarding career for those who are interested in solving problems and making things work. There are many opportunities for advancement in the field, and those with the right skills can become contractors or even branch out into their own businesses. They can even move on to a more engineering-related position, like becoming a building services engineer or an electrical designer. Regardless of the path they choose, an electrician must have excellent interpersonal and communication skills to succeed.
