Breaker Panel

Guide to Circuit Breaker Panels in your Home

The circuit breaker in your home serves two important purposes. It is a conduit for power to flow through your house to the circuits that provide electric power to areas that require it. Circuit breakers cut off electrical power flow when there’s danger. They also protect the circuits. We’ll be discussing the function of circuit breaker panels and the time when you may want to upgrade or replace them.

It’s unlikely that you think of this particular component very often, but it’s one of the most crucial components of your home’s electrical system. It’s referred to as a circuit breaker box or the breaker box.

It is vital because the majority of electricity used in your home flows through it and those circuit breakers. If it’s correctly configured then you’ll never think twice about it.

If the equipment isn’t sufficient It could be extremely inconvenient or even create safety issues for your home.

This article will provide an explanation of the definition of an electrical panel and how it works. We’ll also go over some of the reasons to have the main panel for your breaker to be inspected by a qualified electrician of Texas Solar Group. Let’s begin by understanding the fundamentals of a circuit breaker box.

What is a breaker panel and how does it work?

The circuit breaker box connects the electrical grid that is outside your residence to wiring within. It is the primary service panel that controls all electrical outlets and lighting, heating and other devices.

The service drop is a way through which power is brought into the breaker box through the outside. This could come from power poles or buried power lines. This electricity is then distributed through branch circuits to provide power to your home.

You should also be familiar with other names

“Breaker panel” is a name that refers to the circuit breakers which supply electricity to the branches that originate to the panel. It can also be referred to by a variety different names. It could also be referred to as the circuit breaker, breaker box or electrical panel. It functions in the same way no matter what name it is.

How it works

Circuit breakers are vital security devices that shut off branch circuits if they sense an overload. This is the reason you may have observed a circuit interrupter that is tripping (shutting down) after plugging in several appliances in your kitchen.

The fuse box is an older version in the event that you’re older and reside in an older residence. Fuse boxes’ primary function was to protect your branch circuits from overloads. But, a fuse that has blown must be replaced in order to restore power to the circuit. Circuit breakers can be reset by turning the switch.

Capacity of the breaker box

Amperage capacity is probably the most crucial figure to learn about your panel. It is also known as amps. (or amps) is a measurement of how much electricity is used. The capacity of amperage in the breaker panel in your home has increased as homes get bigger and more electrical appliances are being used. Although circuit breaker panels with 200 amps are standard nowadays there are panels or fuse boxes with ratings as low as 60 amps in homes built prior to the 1960s.

Where can I find my main fuse box?

It is possible that you are uncertain about where your breaker panel is in case you’ve never used it. There are several common locations.

Garages are often found in common areas. They’re usually positioned against an exterior wall, in which power is supplied through the service drop.

It’s not uncommon to locate the panel for a breaker in a basement, if there’s a buried powerline.

Another place that’s not common for single-family homes but may be more common in a townhouse or duplex is on the lower levels of hallways, in the pantry in the kitchen or in an utility closet.

An exterior wall is a less common spot which you may find in older homes.

A look inside your electrical panel

Let’s get through the panel by opening it up.

It is impossible to see what you don’t know.

The primary breaker panel can be found inside the box. There are some switches. Below that is the ground and hot bus bars. Every single switch is equipped with ground and powered wires connected to it.

Main switch

The panel’s top will be equipped with one switch. This is your main breaker. This will turn off the power supply to your home.

Individual circuit switches

Two rows of numbers is the initial thing that you notice when you open the panel’s door. These constitute your circuit breakers. Each one is responsible for the home’s circuit. The circuit breakers should be set to ON to allow power to flow through them. This circuit is cut off when the switch is turned off.

A piece of paper with the information for the number can be found within the door’s door panel. The card could read “1 Kitchen Outlets.” It is possible to turn the switch on or off to shut off power to your kitchen outlets.

It is common that the card is difficult to read or badly written. It’s best to spend some time with another person to go over the controls of the switch and ensure that the card is legible and accurate. This will allow you to understand how to shut off the power supply to circuits, for instance, if you have to change an outlet or wall switch.

Switches with single-pole or double-pole poles

Your panel can have two kinds of circuit breakers.

  • Single-pole breakers are described as single switches having an amperage of between 15 and 20 amps. These switches are common in household circuits with 120 volts.
  • Double-pole breaker refers to the double switch that has two switches linked. These are designed to handle more than 240 V, and come with greater amperage ratings. They can be connected to high-voltage circuits such as water heaters, furnaces and air conditioning.

The sub panel

It is possible to find an additional panel next to your main box in certain cases. There may be an outbuilding that you need to operate on a separate system or because you have modified the electrical system of your home. If a backup generator is connected to the home’s electric system, then a sub-panel could be employed.

The size that you need

You might find an article on the rating of breaker panels when you read about panel upgrades and breakers panels. The most common ratings discussed being 100-amp and 200-amp. These ratings indicate the power of the electrical panel.


These panels are not suitable for homes equipped with central heating or air conditioning. A 100-amp panel is utilized to power appliances, lights, and receptacles.


They are a standard feature for new construction and can be utilized for a typical electrical requirement. You may need a larger panel box if your house requires more power or is big.


These panels are useful for large homes that have many electrical requirements in particular if the electricity is used to heat the home. You might need to upgrade your panel to a 250-amp or larger model if you’re upgrading the electrical system within your home for an addition, workshop, or outbuilding.

Signs your current panel is not up to the job

You’ve probably experienced the circuit breaker go off if you’re like most people. It’s time to turn off your blender, reset the breaker and get on with your life.
