Electricians install electrical wiring, lighting fixtures, and other appliances. They also connect or disconnect power for equipment like generators, motors, and pumps. They read blueprints and other technical diagrams to plan projects. They use a variety of hand and power tools, including screwdrivers, wire strippers, conduit benders, and drills. They are also skilled at using specialized tools like voltmeters, ammeters, and thermal scanners to test and inspect electrical systems.
Some electricians specialize in new installation projects. This may include putting in recessed lights, ceiling fans, and outdoor landscape lighting. They also might do lighting upgrades, such as putting in LED or energy-efficient light bulbs.
Other electricians are more experienced in service and repair work. They might work for residential, commercial, or industrial customers. They might do emergency repairs, such as fixing a tripped circuit breaker. They could also do larger projects, such as putting in wiring in an entire house or office building. This type of work can involve a higher degree of skill, as the electricians have to deal with higher voltages and more complex electrical systems than those found in homes.
When a customer complains about flickering or dimming lights, it could indicate that the wiring is outdated or overloaded. A licensed electrician can check the circuit breakers, replace old fuses, and even rewire the circuits to resolve these issues.
An electrician can also do other types of maintenance work, such as ensuring that outlets are child-proof and properly grounded. They can help homeowners install and setup home security systems, such as alarms and cameras. They can also put in ceiling fans, mount televisions on mantels, and install a wide variety of light fixtures, including chandeliers, bathroom sconces, and paddle fans.
Some electricians are experts in specific technologies, such as solar, wind, or hydropower energy systems; backup and emergency generators; EV chargers; lighting control and efficiency systems; and data communication wiring. These electricians often work alongside architects, engineers, and other professionals to design and build these technologies. They also ensure that these systems meet local and national electrical codes and safety standards.
Troubleshooting
Electrical problems can be frustrating, and they can also be dangerous. Flickering lights or outlets that buzz can be indicative of serious issues that need to be addressed immediately before they cause damage to appliances, fires, or even electrocutions. Electricians can help customers identify electrical problems and provide them with solutions to repair or upgrade their systems.
One of the most important skills that electricians possess is troubleshooting. Electrical systems can be complex, so determining what is causing a problem can be difficult. Electricians use a series of techniques to troubleshoot, or determine the source of an issue. These steps include visually inspecting the system, using testing equipment, and referencing wiring diagrams.
When a problem arises, the first thing an electrician will do is conduct a visual inspection of the system. This will help them find any signs of damage or wear that may be causing the problem. They will then use testing equipment to measure the input and output signals of the system in order to zero in on the source of the problem.
Once they have isolated the source of the problem, they will be able to fix it. If it is a simple issue, like a blown fuse or a tripped breaker, they can replace the appropriate component and solve the problem. If it is a more serious issue, they can repair or replace the entire fixture.
In addition to using hand and power tools, such as screwdrivers, wrenches, and wire strippers, electricians can also work with a variety of test equipment, such as multimeters, thermal scanners, and voltage meters. They can also read blueprints and technical diagrams to locate circuits, outlets, and switches.
Oftentimes, a common electrical problem is something as simple as not plugging in an appliance properly or having it plugged into the wrong outlet. If you have an intermittent problem with an appliance, try plugging it into a different outlet to see if the problem persists. If it doesn’t, you know the problem is with the outlet or circuit and not the appliance itself. It is a good idea to keep a notebook while you troubleshoot so that you can write down what you are doing and note any results. This will save you time and effort, and it can also help you avoid making mistakes that could lead to more serious issues in the future.
