Electricians are essential to the operation of homes, businesses, and industrial facilities. This career combines technical expertise with physical work and meticulous attention to detail.
Rather than attending school to earn a degree, most electricians learn their trade through a four- or five-year apprenticeship program. This apprenticeship allows them to earn a living while they train. Contact Nash Electric LLC now!
The wiring in a house is the conduit that carries electricity from the power source to switches, outlets, and other appliances. In many older homes, the circuits are overburdened, straining to supply the many electricity-hungry gadgets in use. The wires themselves often need to be updated. An electrician can inspect the wiring and make upgrades as needed.
Wires and cables have markings stamped or printed on their insulation or outer sheathing that tell electricians important information. These include the wire size, material and number of wires inside a cable. The size tells electricians how much current the conductor can safely carry. The insulation also has an electrical resistance rating, which is how much heat the conductor will dissipate.
An electrician needs to understand how to read and interpret an electrical wiring diagram before beginning a project. This will help them plan for the right amount of wire and anticipate when they will need to add more. It will also help them avoid making mistakes that could result in a fire or other dangerous situation.
Every home has a service panel that distributes electricity to switches, outlets and other appliances. This panel is usually located in the basement or garage and is the place where you shut off power to a particular circuit before working on it.
All new installations of electrical wiring are required to be color coded. This is to prevent accidental contact between live and neutral wires, which can cause a fire. The colors used are determined by government regulations and may vary from country to country.
A professional electrician can install electrical wiring in a variety of ways, including running it through a receptacle box and then using it to connect to the switches and other devices. They can also install it in a wall or ceiling by using metal conduit. This is a more involved process that requires cutting and shaping the conduit, but it provides a more durable solution than simply running the wires through holes in a stud.
DIYers can save money by installing their own wiring, but they should have a thorough understanding of electrical wiring before starting a project. They should also make sure they are properly qualified to do the work or know someone who is. An injury caused by improper wiring can be very serious and even deadly.
Circuit Breaker Installation
Adding or replacing a circuit breaker is one of the most common jobs for an electrician. Homeowners may need to add a new circuit for an expansion of their electrical system, or replace a faulty breaker that is overheating or causing a fire hazard. There are many important safety precautions to be aware of before attempting this task. It is important to turn off the power supply to the breaker panel before working and to wear rubber-soled shoes, gloves, and insulated tools. It is also important to test the incoming wires with an electrical tester to ensure they are not live before working with them.
A breaker panel is a metal box that contains the breakers that control electrical current in your home. It is usually located in a utility room, basement, or garage and has a hinged door that covers the breaker terminals inside. A professional electrician will shut off the power supply to the breaker panel and disconnect the large black wires feeding into it before opening the cover and removing the breaker. The breaker panel should be clean and free of debris or dust.
If you are adding a new circuit, first choose the location in the breaker panel where you want to install it and note any unused spaces. Then locate the knockout tabs in the breaker panel cover that are pre-punched to accommodate electrical wiring. These holes are used to feed the wires through, and they can be opened with a screwdriver or hammer. Once you have a space to feed the new breaker wire through, loosen the screws holding the panel cover in place and set it aside.
Next, remove the breaker from its packaging and identify its voltage and amperage. It is important to use a breaker that matches the amperage and voltage of your electrical system to prevent overheating or fires. If you are installing a new circuit for a living area, it is required by code to use an arc-fault circuit interrupter (AFCI) instead of a standard breaker.
Once you have the correct breaker in place, reattach the panel cover and tighten the screw holding it in place. Then, reattach the wires to the appropriate terminals on the new breaker and connect them to their corresponding bus bars. Once you have everything connected and the breaker is in the on position, turn the power back on and test it for proper operation.
Troubleshooting Electrical Problems
When you’re experiencing electrical problems at home, it can be difficult to determine where the problem lies. Luckily, there are some straightforward techniques that you can try before calling in a professional.
1. If the Outlet or Switch Is Warm, Then You May Have a Problem
You can tell if an outlet or light switch is faulty by touching it. If it feels hot, that means that the current is flowing through it more than it should. If this happens frequently, then you should call an electrician to repair it.
Another way to test an outlet is by plugging something into it. If it doesn’t work, then the outlet likely has loose contacts that need to be tightened. If it still doesn’t work, then you should replace it with a new one.
- If the Circuit Breaker Keeps Tripping
It’s important to assess your electricity usage before determining what’s causing the breaker to trip. If it’s a regular event, then you might be overusing the power in that area of your house. This could mean that you’re running too many appliances at once, or that your household appliances are outdated and not up to New York state requirements.
Once you’ve determined what the cause of the tripping is, turn off all of the switches in the area that’s affected. Then, use an ohm meter to test the connections on each of the wires leading into that outlet. If a wire isn’t connected properly, or it’s frayed, it can draw too much current and create a fire risk.
- If the Electrical Power Is Constantly Flickering
A flickering light can be caused by a variety of issues, from a simple bulb replacement to an unstable electrical system. A qualified electrician should be able to inspect your wiring and fixtures to ensure that they’re up to code.
Power surges are also dangerous and can damage your electronics. They’re often caused by lightning strikes or electric company slip-ups. However, you can protect your appliances by using surge protectors. In extreme cases, you’ll want to hire an electrician to look for a serious issue like a short circuit that could be causing your devices to overheat and burn out.
Electrical Safety
Electricity is dangerous, even in low voltage forms. It requires the knowledge, skills and focus of a professional to work safely. Every year, 411 people die from electrocution on the job, and thousands more sustain serious injuries. That is why service professionals must always follow best practices when working on electrical systems – at home, in commercial sites and in industrial environments.
Electrical safety begins with ensuring that the circuit is not energized, and this can be done by using a multimeter to check for volts before touching wires or equipment with gloves. If there is any doubt that the circuit is energized, it must be locked and tagged out according to the company’s Lockout/Tagout procedures before any electrical work can take place. This can be achieved by shutting all panel doors and making sure that all exposed electrical contacts are capped.
Other safety precautions include observing any signs of electrical hazards and having them corrected immediately. Damaged insulation, for example, can increase the risk of shock and fire. Keeping electrical cords away from water sources, installing ground fault circuit interrupters (GFCIs) in wet areas and ensuring that any confined spaces have adequate ventilation all reduce the risks of fire, shock, and tripping.
Having the proper personal protective equipment is also vital, including wearing the right PPE such as safety glasses, hard hat and insulated gloves. Cluttered workspaces also raise the dangers of accidents, so good housekeeping and a well-planned layout of electrical cords are important.
Finally, it is crucial to have regular electrical inspections performed. These can identify potential problems like overheated circuits and devices, and help prevent equipment failure, electrical burns or other hazards.
Working with electricity demands the highest level of technical understanding, which is why only trained professionals should perform these tasks. This could be through a combination of licensing, completion of an apprenticeship or formal education and training, or on the job experience. However, no matter the qualification, one thing is essential: a good understanding of the principles and hazards of electricity, both high and low voltage.
