Common Electrical Questions Answered
Can I repair my own electrical system?
Electrical work can be dangerous. If you don’t have any idea what to do or where to start, you need to hire an electrician to take care of any electrical needs you have. You don’t want to get injured due to not having enough knowledge. Don’t let electrical work scare you, there are some projects homeowners can do on their own. For example, you can change out light switches, receptacles, and light housings. Make sure you switch off the breaker to the electrical circuit you are working on before you start any project.
What is a GFCI outlet?
Do you know the outlets with the test and reset buttons? Those are GFCI outlets. GFCI stands for ground fault circuit interrupter. These outlets are used in wet areas of a home like a kitchen and bathroom. This outlet works by killing the power to the circuit if it senses a difference in the outgoing and incoming current. These outlets help prevent electric shock due to faults.
What’s the difference between a fuse and a breaker?
Fuses and breakers perform similarly. They disrupt the flow of power when there is a fault in the system. The major difference between a fuse and a breaker is that when a fuse trips, it needs to be replaced. When a breaker trips, it can be easily reset. That is why breakers are used more than fuses.
Why is my breaker tripping?
Have you lost power in a section of your home and when you go to your panel to check you see a breaker has been tripped? That is an electrical panels way of keeping you safe. When there is too much load on the circuit, the breaker will trip. The breaker trips to prevent your wiring from overheating.
How do I reset a tripped breaker?
- Locate the electrical panel and open the cover.
- A tripped breaker will be in the “off” position, or somewhere between “on” and “off”.
- Reset the breaker by moving it to the full “off” position and then back to the “on” position.
- This should restore power.
If the breaker trips again, it could be because too many things are plugged into the circuit, damaged wires, bad switch, or faulty wiring. If it keeps tripping, call a licensed electrician
to troubleshoot the issue for you.
Should I upgrade my 100 amp to 200-amp service?
Most older homes have 100-amp electrical panels. There wasn’t as much power being used then as there is now. New technology has increased the amount of amps homeowners need for all the new appliances and devices. It is worth the money to upgrade your service to a 200 amp to make sure you have enough power when you need it.
It is best to have an electrician do the upgrade. Call us

Every time a circuit breaker trips in your home, it’s doing something incredibly important—protecting you and your electrical system from danger. But have you ever wondered where these little safety devices came from, or how we protected homes before they existed? Here’s a quick look at the evolution of electrical breakers, and why they’re one of the most important inventions in modern electrical safety. ⚙️ Before Breakers: The Age of Fuses (Late 1800s – Early 1900s) Before circuit breakers became common, homes used fuses to prevent electrical overloads. A fuse contains a thin wire that melts when too much current flows through it, stopping the circuit. The problem? Once a fuse blows, it has to be replaced—every single time. Fuses worked, but they were: Inconvenient Easy to install incorrectly Prone to over-fusing (dangerously replacing with a higher-rated fuse) ⚡ Enter the Breaker: Early 20th Century Innovation The concept of the resettable circuit breaker emerged in the early 1900s, offering a reusable, more reliable solution. The first patent for a circuit breaker came in 1924 by Hugo Stotz (working with Siemens), whose design used a bimetallic strip to detect overcurrent. Breakers gained popularity throughout the 1930s–50s, especially in industrial and commercial buildings. Why they caught on: Could be reset instead of replaced More precise at detecting electrical faults Better suited for growing electrical demands 🏠 Breakers in the Modern Home (1960s–Present) By the 1960s and 70s, circuit breakers became the standard in new residential construction across the U.S. and many parts of the world, replacing fuse boxes entirely. Modern home panels include: Standard breakers – for basic overcurrent protection GFCI breakers – to protect against shock (especially near water) AFCI breakers – to prevent electrical fires from arc faults Dual-function breakers – offering both GFCI and AFCI protection These advanced breakers are required by modern electrical codes in many areas, and they’ve drastically reduced electrical fires and injuries. 🔌 Why Breakers Matter More Than Ever Today’s homes use far more electricity than they did 50 years ago. With more appliances, electronics, EV chargers, and smart tech, the demand on your electrical panel is greater than ever. Circuit breakers are the unsung heroes, silently monitoring every circuit to: Prevent overloads Stop short circuits Protect people and property 🧑🔧 Should You Upgrade Your Breaker Panel? If your home still has an old fuse box or outdated breaker panel, it might be time for an upgrade—especially if you’re: Experiencing frequent tripped breakers (check out our blog about troubleshooting electrical circuit tripping ) Adding new appliances or renovations Living in a home over 30–40 years old Find you need to upgrade your panel?

Noticing your lights flickering lately? Whether it's just a quick blink or a persistent issue, flickering lights aren't something to ignore. While some causes are harmless, others can be a sign of a much bigger electrical problem lurking behind your walls. We believe in addressing electrical issues early—before they turn into safety hazards. Here’s what flickering lights could mean, and when it’s time to call in a professional: ⚠️ Loose or Faulty Bulbs Let’s start simple. Sometimes, flickering is just a matter of: A loose bulb in the socket An incompatible bulb, especially with dimmer switches A bad connection between the bulb and socket contacts 🛠️ Try turning the bulb off, tightening it, or replacing it with a fresh one. If the problem stops—great! If not, keep reading. ⚡Overloaded Circuits Do your lights dim or flicker when you run the microwave, HVAC system, or vacuum cleaner? This could mean: A circuit is overloaded and struggling to supply enough power Your electrical panel may be undersized or outdated for your current energy needs ⚡ Solution: An electrician can evaluate your system and recommend upgrades, such as a panel replacement or circuit expansion. 🔌Faulty Switches or Loose Wiring Flickering in a single fixture—especially when touched or adjusted—may point to: A loose connection in the light switch Frayed or deteriorating wires behind the wall A faulty fixture that’s wearing out 🔥 Loose wires can generate heat and even lead to electrical fires—don’t delay an inspection if this sounds familiar. 🏡 Whole-House Flickering Lights flickering throughout your home? This could signal: Issues with your electrical panel or main service line A failing main breaker Problems with the utility company’s supply line This is a more serious issue that requires a licensed electrician’s immediate attention. ⚠️ Never ignore widespread flickering—it’s often a sign of a potentially dangerous voltage problem. 🌩️Power Grid Fluctuations or Storm Impact Sometimes flickering comes from outside your home. Storms, power line damage, or utility equipment issues can all cause fluctuations in your service. We have a blog about how to set your house up for stormy weather. Check it out here ! While these may resolve on their own, frequent or prolonged issues should still be evaluated to protect sensitive electronics and ensure safety. 🧑🔧 When to Call a Pro If flickering lights happen often, are unpredictable, or are accompanied by: Burning smells Buzzing from outlets or panels Warm switches or outlets Tripping breakers 👉 It’s time to call a licensed electrician.
