Different Types of Circuit Breakers: Everything You Should Know

March 22,2021

The electrical panel is so humble, effective, and silent that most property owners never give it a second thought - until something goes wrong. It’s easy to forget that your electrical panel is doing some pretty heavy lifting behind the scenes, but responsible homeowners and business operators understand that the electrical panel deserves care and attention.

If you're not familiar with the electrical panel, then keep calm and read on. In this brief article brought to you by Mr. Electric, we introduce you to this integral part of the electrical system and take a closer look at how it works - and how it should NOT behave.

Those who are looking for certified electricians in Greer, SC and surrounding areas can call Mr. Electric to hire a uniformed local professional today. We're happy to address questions and concerns, schedule an appointment, or arrange an emergency electrical service for as soon as possible.

What Exactly Is an Electrical Panel?

An electrical panel (also known as a breaker box, fuse box, or load center) is a box that you’ll find on a wall in a utility room, basement, garage, or hallway closet. Open the lid and you’ll see rows of switches called circuit breakers. Each one of these breakers controls power to a specific area of your building.

The electrical panel connects to the main power line from your utility company and acts as a traffic director by sending power where it’s needed while shutting down any circuit that behaves badly. That’s what makes it so critical: when a breaker trips, it’s often preventing overheating, electrical fires, or damage to appliances.

Types of Circuit Breakers (And Why They Matter)

Now that we understand the general role of the electrical panel and circuit breakers, let's dive a little deeper. As it turns out, there are several types of circuit breakers. Here are a few common types you should know:

  • Standard Single-Pole Breakers: These are the most common and handle 15-20 amps of electricity. They control individual circuits and trip when they detect an overload or short circuit.
  • Double-Pole Breakers: These can handle 20-60 amps and are used for larger appliances like dryers, ovens, or HVAC systems. They provide 240 volts.
  • GFCI Breakers: These are typically found in kitchens, bathrooms, outdoors, and anywhere with moisture. They're designed to shut off power when they detect even tiny electrical leaks - often caused by moisture or faulty wiring.
  • AFCI Breakers: Arcing is when electricity jumps between wires, and it can create enough heat to cause fires. AFCI breakers monitor for this dangerous condition and cut power if detected.
  • Combination Breakers: This includes AFCI and GFCI protection.

Is It Time for an Electrical Panel Upgrade?

Your electrical panel isn’t forever. Over time, parts wear down, homes get renovated, and our power demands increase. What was once perfectly fine for a 1980s house might not be safe for a home full of smart devices, induction cooktops, and dual-zone HVAC, for instance.

Here are some signs that it might be time to consider an electrical panel upgrade:

  • Frequent Breaker Trips: This is your panel telling you something’s off; either the circuit is overloaded or the breaker itself is wearing out.
  • Flickering or Dimming Lights: This could be a sign of overloaded circuits or voltage fluctuations.
  • Burning Smell or Warm Panel: You could be dealing with faulty wiring or an overheating breaker.
  • Buzzing Sounds: Think of this as an electricity leak. Have it checked out immediately!
  • Rust or Corrosion: Water and electricity make a dangerous mix. Rust on your panel or breakers is a red flag that water is getting in somewhere.
  • You Still Have a Fuse Box: Fuses were fine in their day, but they don’t offer the same safety features as modern circuit breakers.

To be clear, a circuit breaker repair can have you back on schedule many times - but this is something to determine with the guidance of a certified electrician.
