  • Why does my circuit breaker keep tripping?

    Repeated breaker trips are commonly caused by overloaded circuits, short circuits, ground faults, faulty appliances, or a breaker that has reached the end of its service life.

  • How do I know if I need a circuit breaker replacement?

    If your breaker trips frequently, won't reset properly, feels hot, or shows visible signs of damage, it should be inspected by a licensed electrician to determine whether replacement is necessary.

  • Can a bad appliance trip a circuit breaker?

    Yes. A malfunctioning appliance can overload a circuit or create a fault that causes the breaker to trip repeatedly. Disconnecting the appliance may help identify the source of the problem.

  • Is it safe to keep resetting a tripped breaker?

    No. If the breaker continues to trip, repeatedly resetting it without correcting the underlying issue may increase the risk of electrical damage or fire.

  • Should I replace a circuit breaker myself?

    Circuit breaker replacement involves working inside an electrical panel and should always be performed by a qualified electrician with the proper training and safety equipment.

Overloaded Circuits

If your business has expanded but the electrical system hasn’t kept up, you may be exceeding the safe capacity of certain circuits. This can lead to:


  • Breaker trips
  • Overheating
  • Equipment malfunctions
  • Increased fire risk

Uneven distribution of electrical load across phases can cause voltage drops or surges. This may lead to equipment wear and reduced energy efficiency.

Rewiring Options for Occupied Homes

Safety and Code Compliance

  • GFCI protection in kitchens, bathrooms, and outdoor outlets

Common Power Distribution Issues in Commercial Buildings

A small main panel may not support your business’s long-term needs. If you're constantly adding equipment or rearranging workspaces, it may be time to upgrade your panel or add subpanels.

Installation of New Wiring

Once installed, we test the system thoroughly to ensure everything is functioning properly. We also coordinate with your local inspection authority to ensure the rewire meets all code requirements.

Lack of Proper Labeling

When to Upgrade or Modify Your System

You may need to evaluate your power distribution system if:


  • You’re expanding your business or adding machinery
  • You’re renovating part of the building
  • You’re moving into a new commercial space
  • Your staff frequently experiences power issues
  • You’ve failed a recent inspection or insurance audit


NJC Electric works with businesses in Elizabethton, Johnson City, Bristol, and other nearby areas to design and install commercial electrical systems that support growth and compliance.

Backup Power Options

Electrical safety is something many homeowners overlook until there’s a problem. But when it comes to preventing shocks, fires, and costly repairs, a proactive approach can make all the difference. Whether you live in a historic home in downtown Elizabethton or a newer build on the outskirts of town, these essential tips can help you maintain a safer home environment.


Here are five practical and important electrical safety tips for homeowners in Elizabethton and surrounding Tennessee communities.

1. Never Ignore Flickering Lights or Tripping Breakers

It’s easy to dismiss a flickering light as a loose bulb or a tripped breaker as a one-time inconvenience. However, these are often warning signs of a deeper electrical issue.


Flickering lights can indicate:


  • Loose wiring connections
  • Overloaded circuits
  • Voltage fluctuations
  • Faulty switches or fixtures


Frequent breaker trips may signal:


  • Circuits exceeding capacity
  • Short circuits
  • Faulty appliances
  • An aging electrical panel


If you experience these problems more than once, have a licensed electrician investigate. These issues can escalate into serious safety hazards if left unaddressed.

2. Test Smoke Detectors and GFCIs Monthly

Your home’s first line of defense against fire and electrical shock are devices designed to detect danger and shut off power before it causes harm. But these systems need to be tested regularly.


For smoke detectors:


  • Test each unit monthly using the test button
  • Replace batteries at least once per year
  • Replace the entire unit every ten years


For GFCI outlets:


  • Press the “test” button once a month
  • Ensure the outlet shuts off and resets properly
  • Install GFCIs in all wet areas, including bathrooms, kitchens, laundry rooms, and outdoor outlets


In Elizabethton homes built before the 1990s, GFCI protection may be missing or outdated. If your home lacks these critical safety features, schedule an upgrade with a qualified electrician.

3. Avoid Overloading Power Strips and Extension Cords

Extension cords and power strips are useful tools, but they are not designed for permanent use or heavy electrical loads. Overusing them can overheat wiring, trip breakers, or lead to electrical fires.


Best practices include:


  • Plug major appliances directly into wall outlets
  • Do not chain multiple power strips together
  • Use extension cords temporarily, not as permanent wiring
  • Choose cords rated for the load you are connecting
  • Never run cords under rugs or furniture


If you find yourself relying heavily on extension cords in one part of the house, it may be time to add more outlets or upgrade the circuit.

4. Schedule Routine Electrical Inspections

Electrical systems can deteriorate over time, especially in older homes. Wires may fray, insulation can wear down, and circuit loads may become unbalanced. Many electrical hazards are hidden behind walls, making them difficult for homeowners to detect.


A professional inspection by a licensed electrician should include:


  • 5. Hire a Licensed Electrician for All Major Electrical Work


Homes in Elizabethton that are more than 30 years old or have undergone DIY renovations are especially at risk for outdated or unsafe wiring. Regular inspections help catch problems before they lead to fire, equipment failure, or injury.

5. Hire a Licensed Electrician for All Major Electrical Work

When it comes to home improvements, some projects are better left to professionals. Electrical work that seems simple—such as replacing a light fixture or moving an outlet—can quickly become dangerous if done incorrectly.


Hiring a licensed electrician ensures:


  • The work is up to local and national code
  • Proper permits are pulled where required
  • Systems are safely installed and grounded
  • Your homeowner’s insurance remains valid


DIY electrical repairs not only risk personal injury, but they can also void insurance claims if a fire or damage occurs as a result. In Tennessee, permits are often required for panel upgrades, rewiring, or adding circuits. NJC Electric handles these details for you, ensuring everything is done right the first time.

Additional Tips for Families with Children

If you have young children at home, take extra steps to ensure safety:


  • Use tamper-resistant (TR) outlets to prevent objects from being inserted
  • Keep cords secured and out of reach
  • Avoid using outlet covers that can be pulled off
  • Educate kids early about the dangers of electricity


Childproofing your home’s electrical system is a simple but important way to prevent accidents.

When Should You Schedule a Home Electrical Safety Check?

It’s a good idea to have your home’s electrical system checked every five to ten years, depending on its age and the complexity of the system. You should also schedule an inspection if:


  • You recently purchased an older home
  • You’re planning a renovation or addition
  • You’ve experienced tripping breakers or dimming lights
  • You’ve added major appliances or equipment
  • You’re selling your home or preparing for appraisal
