Tom Tanski, electrical and advanced electrical program instructor at Apex

Get to Know Tom Tanski, Electrical & Advanced Electrical Program Instructor

“Teaching is the most rewarding job I ever had, and I can stay involved with the trade I love.”

A Legacy in the Trades


Tom Tanski comes from a long line of master craftsmen. His father was a general contractor and master plumber. His maternal grandfather was a union electrician, and many other family members were in construction. “I grew up doing carpentry and plumbing,” Tom says. “As soon as I was old enough to push a broom, I was on a construction site.”

Tom worked as a framing carpenter in his 20s. When he decided to become an electrician, he spent seven years attending night school while working during the day to learn his trade. He rose to the top of the profession and became a foreman, before a freak bowling injury derailed his career. He was 34.

I just picked up a bowling ball, there was a rupture, I had nerve damage and lost fine motor skills in my right hand.

A Fresh Start with Apex

While working as a traveling superintendent, living in hotel rooms across the country, Tom saw an APEX ad looking for teachers for its Electrical & Advanced Electrical program. He wasn’t sure he had the patience to teach, but he went to the interview anyway. That was 14 years ago.

“Teaching is the most rewarding job I ever had, and I can stay involved with the trade I love,” Tom says. “Most tradespeople don’t see themselves as teachers, yet all of us have taught apprentices in the field. We are teachers; we do this all the time. For any tradesperson who has physical limitations like I do, or anyone who has retired from the field but wants to work, this is the perfect career.”

The trades are more technically advanced than most people understand. In the electrical trades, for example, teachers and students alike are at the forefront of technology. Smart homes, next-generation solar technology, and electric car recharging stations all rely on electricity—one of the reasons why career prospects are so great for electricians.

There is so much that is rewarding about teaching for Tom. He can travel anywhere in the country and see buildings his students helped to construct. He loves seeing the moment when students finally grasp a difficult concept. And he loves giving back—one of his students was living in a shelter when he started the program, and now has his own apartment and pays his own bills.

“I was part of changing that student’s life. I never had a job before that offered that kind of reward. There is a pride in knowing you had that impact on someone’s life.”

Work Safer with These Electrician Tips

Individuals who work in the electrical field often enjoy a hands-on experience on the job. Electricians require practical skills, the ability to work alone or with others and a passion for problem-solving. The working environment for an electrician may be in a large commercial building or a small corner in a residential home. No matter where electricians apply their skills and knowledge, they should understand and follow electrical worker safety standards.

Electrical safety is critical, whether you’re an electrical student starting training classes or you’ve been working in the electrical field for decades. Safe protocols and gear can protect people, property and things from dangers such as burns, sparks and electrical fires. Explore some electrical safety tips and keep these top-of-mind when you’re handing electrical wiring.


Assess the Work Setting

An electrician assesses a breaker box before beginning his repairsWhen an electrician arrives on a jobsite, he or she should pause and gain an understanding of the environment. Where is the electrical box? Are there current dangers, such as smoke or water near electrical currents? If the situation is not an emergency, are there any potential hazards? Incorrectly installed equipment may not be immediately noticeable. Take a few moments to look over the work setting and prepare yourself for the job at hand.

Equip Yourself with Safety Gear

Safety gear is one of the most important parts of staying safe in the workplace. It’s a good idea to keep all your electrical safety gear with you when you travel to jobsites so you aren’t putting yourself at risk. Items like insulated gloves protect your hands from electrical currents, while protective eyewear keeps your vision safe from sparks.

If you are working on a construction project with the potential for falling debris, don’t forget to wear a hard hat to ward off injuries from heavy or sharp objects. Some individuals wear flame-retardant clothing that covers your arms and legs. In the event that an electrical spark starts a fire near you, fire-retardant clothing can keep your skin protected from burns.

Use a Multimeter to Test Wires

An electrician uses her multimeter to safely check electrical wiresA multimeter is a handheld electrical tool used to test voltage, resistance and current. This tool may be standard in the electrical trade, but it is important for testing to see if a wire is safe. If the multimeter determines the component is weak enough, you can safely handle or touch the wire during the repair job. Always use a multimeter to test wires; other tools like screwdrivers or wrenches should not be used to check potentially live components.


Electrical safety is the first rule of working in the electrical trade. With electrician training, you can help keep your work environment safe and productive. Learn more about the Electrical & Advanced Electrical program at Apex Technical School. Classes are starting soon!

What is residential electrical wiring vs. cable?

Electrical wire is a material that conducts electricity, and it is usually made of copper or aluminum. Most residential wires are wrapped in a nonconductive plastic coating. The plastic coating is sometimes called a jacket. A combination of two or more wires is called a cable. These are also wrapped inside a jacket to insulate the wires from touching other objects.

How do you read labels on electrical wiring?

The jacket, or insulation on an electrical wire is stamped with a code. This special code tells you what type of electrical wiring it is, as well as characteristics about its performance. THHN and THWN are the most common types of electrical wire used in residential construction. These letters stand for:

  • T: Thermoplastic, a heat-resistant plastic
  • H: Heat-resistant up to 167F
  • HH: Heat-resistant up to 194F
  • W: Moisture-resistant
  • N: Nylon-coated to resist damage from oil and gasoline

Nonmetallic cables also have codes and lettering on them, indicating the number and size of wires inside the jacket, or plastic coating. Common labels on nonmetallic cables include:

  • Nonmetallic Sheathed Cable (NM-B): Standard for dry indoor locations
  • Underground Feeder (UF): Suitable for outdoors and in-ground
  • Service Entrance (SE): Suitable for above-ground appliances and bringing power from a transformer to a house
  • Underground Service Entrance cable (USE): Suitable for outdoors and in-ground, similar to SE cables

Finally, the numbers on a nonmetallic cable tell you about the wiring size and number of wires inside the jacket. For example, a jacket with “12/2” contains two 12-gauge insulated wires.

What is cable jacket color coding?

In addition to lettering and numbering, electrical wiring and jackets come in different colors to indicate how to use them. Color coding is a valuable tool in the electrical trade because it makes wires easily identifiable and promotes safer jobsites.

Components needed for rewiring a house wall socket

Residential Electrical FAQs

Electrical problems can be unsettling for most homeowners. Electricity powers many appliances in the home—and when it’s not working, it can be an inconvenience. Some electrical issues can also pose a potential fire hazard. These should be addressed right away by an electrician. In fact, all electrical problems, from a short circuit to rewiring a house, should be handled by a qualified individual with electrical skills and knowledge. Check out these common questions homeowners might ask about the electricity used to power items in their homes. 

What uses the most electricity in your home?

This basic electrical question is one of the first questions homeowners may ask. Residential energy consumption is the third-largest use of energy in the United States. These are the 10 most common sources of electricity consumption in 2019, as projected in the Annual Energy Outlook 2020: 

  1. Space cooling
  2. Space heating
  3. Water heating
  4. Refrigeration
  5. Lighting
  6. Clothes dryers
  7. Televisions
  8. Computers
  9. Furnace fans
  10. Freezers

Sometimes, homeowners don’t know when appliances are actively consuming electricity in their homes. In fact, some appliances use electricity even when they are switched off or not in use! These include printers, microwaves, routers and modems, and gaming consoles. 

Why does aoutlet spark when I plug in a device or appliance?

It’s normal to see the occasional small flash of electricity when you plug in a lamp, hair dryer or other appliance. However, if there is a spark every time you use the outlet—there might be a problem. The outlet could be short circuiting. Short circuits break down insulation and wires, and they are a potential fire hazard. An individual who works in the electrical trade can help diagnose the problem and recommend a solution. 

Why are plugs falling out of my wall outlet?

An electrician helps install a home electrical outlet

Over time and with frequent use, the outlet loosens and wears down. When this occurs, homeowners should have it fixed it right away. Like outlets that short circuit, loose outlets can spark too. These sparks are a potential fire hazard. If a socket is worn out, it is best to replace it right away to stay as safe as possible. Replacing an outlet requires rewiring part of the home’s electrical wiring. Make sure to call a qualified electrician who has the knowledge and hands-on skills to rewire a house wall socket easily and quickly. 



My circuit breaker trips all the time. Why?

This likely occurs when you use too many appliances at one time. And it may be an indication that your electrical circuits were not designed or installed correctly. Some powerful appliances, such as refrigerators and clothes dryers, require their own powerful circuits. An electrician can inspect the home’s circuitry to determine if too many appliances share a circuit, and ultimately make repairs to stop breaker trips.

What is GFCI protection?

A GFCI outlet is designed to protect against electrical shock if it gets wet. GFCI outlets are required in bathrooms, garages, crawl spaces, basements, laundry rooms and other areas where water is present. They have a test button to turn off the GFCI, and a reset button to turn it back on after it has tripped. Having trouble getting a GFCI outlet to turn back on? Call an electrician who will be able to diagnose and fix the issue.

Wire Stripper

Electrical tradesmen often need to strip or cut off insulation wires. Wire strippers are designed with various-sized teeth for cutting a variety of wire sizes. Some wire strippers feature ergonomically designed handles and curved blades that provide clean, precise cuts through tough wire and cable.

Wire Crimper

When an individual joins two pieces of metal wire, he or she generally uses a wire crimper to deform the pieces so they hold together. Wire crimpers allow electrical tradesmen to repair wires causing faulty circuit connections by providing a long-lasting seal.


Most individuals in the electrical industry need a variety of screwdrivers, including Phillips 1 and 2, straight blade screwdrivers, magnetic screwdrivers and screwdrivers with interchangeable tips.


A set of pliers is one of the most common tools of the electrical trade. Diagonal pliers specifically cut wires in tight spaces, while a set of do-it-all pliers with a squared-off tip are ideal for twisting, cutting and pulling wires.

3 Top Trends in the Electrical Technology Industry

Increasingly, homeowners are turning to home alternative energy sources and smart technology to save money on electrical costs. They want electrical technology that is better for the environment and their pocket books. As electrical trends continue to evolve, it’s important to know which innovations are rising to the top of this exciting industry.

Residential Solar Electricity

Solar electricity isn’t a new invention. In fact, it’s been around since 1954 and has been used to power everything from space satellites to calculators and wristwatches.

Today’s homeowners, businesses, and governments are installing rows of solar cells on rooftops, hill sides, and farm fields. These solar cells—also called photovoltaic (PV) cells—convert sunlight into electricity. This feature makes solar power for homes highly desirable to individuals looking to save on electric costs over time.

As technology improves and demand for solar electricity goes up, systems such as solar hot water, solar heating and cooling, and solar electricity are becoming more cost effective for homeowners to install. According to the National Renewable Energy Laboratory, “Because of their flexibility, thin film solar cells can double as rooftop shingles and tiles, building facades, or the glazing for skylights.”

USB Wall Outlets

Grounded outlets have been a necessity in American homes since the 1960s. However, with modern devices like phones, tablets and computers, homeowners want faster, easier ways to charge their batteries.

Outlets designed specifically for USB ports can be installed by swapping out a traditional outlet. A new receptacle can mean homeowners don’t have to choose between the table lamp, charging their phone, and turning on the A/C window unit. Additionally, homeowners can rest easy knowing that as technology evolves, USB outlets are replaceable.

Lighting Upgrades

Many homeowners choose to incorporate more functional and modern lighting in their new homes and remodeling plans. Recessed and under-cabinet lighting offer a practical solution to dark kitchens or bathrooms while adding to the aesthetic of the room. Similarly, focused track lighting is a chance for homeowners to illuminate specific areas of the home, from portraits to art and more.

Tech-smart homeowners, however, choose upgrades that may require specific products and installation techniques. Home automation enthusiasts may want to install wireless lightbulbs, switches, dimmers, or outlets, which they can control by using Alexa, Amazon Echo’s virtual assistant.

Finally, homeowners with electrical panels and systems more than 20 years old generally opt to upgrade their amperage. With older systems, there is the potential for electrical fire. In order to safely provide enough power to a home, someone in the electrical field will inspect and make the proper conversions to ensure the system accommodates appliances in modern homes, including air conditioners, TVs, computers, stoves, refrigerators and lamps.

Nikola Tesla appears on a US stamp for his alternating current induction motor, which outperforms Edison’s direct current.

Tesla vs. Edison: Who Had the Better Electrical Career?

Thomas Edison and Nikola Tesla were contemporaries, and even rivals, as inventors in the late 19th and early 20th Centuries. In fact, Tesla was even an employee of Edison early in his career.

While there’s no doubt that Thomas Edison had a more financially prosperous career as an inventor, historians and engineers could argue that Tesla’s innovative electrical ideas make him the better inventor. Let’s review his accomplishments and career to find out how he impacted today’s electrical industry.

Alternating Current vs. Direct Current

Easily Tesla’s most important electrical contribution, the alternating current (AC) rivaled the direct current (DC) used in Edison’s power plants. Direct current was invented in 1800 by Alessandro Volta and evolved slowly over the years, becoming an everyday utility with Edison’s invention of the household lightbulb in 1882. Direct current refers to the flow of electricity in only one direction and is used by the following:

  • Batteries
  • Power supplies
  • Solar cells

While he was studying math and physics at the Technical University of Graz in 1882, Tesla came up with an alternating current idea. After moving to the United States, working at Edison’s headquarters, and his alternating current idea being rejected by Edison, Tesla pursued AC on his own. While AC had been invented in 1884, Tesla designed and invented an induction motor, which became today’s commonly used three-phase form. The difference between AC and DC is that DC is usually contained within a cell like a battery, and can be drained, while AC electricity flows in both directions and is used when you plug an appliance into an outlet.

With alternative currents the standard today, and considered more efficient than direct current, Tesla’s AC can be called the superior electrical invention. He had the foresight to pursue this complex form of electrical conduction, while Edison dismissed the invention, considering it unworthy of pursuit. As LiveScience explains, “Tesla’s inventions are the backbone of modern power.”

What Held Tesla Back?

LiveScience continues to explain that many of Tesla’s inventions did not outlive him, and he was unsuccessful financially. While extremely intelligent, History.com notes his obvious mental illness, which resulted in debilitating obsessions. Additionally, financial backing was difficult to come by for Tesla’s large-scale innovations.


But despite mental and financial instability, Tesla’s legacy lives on, and his electrical genius cannot be discredited or overshadowed by the business success of Edison.
