Breaker Panel

Guide to Circuit Breaker Panels in your Home

The circuit breaker inside your home performs two crucial functions. It distributes power through your house to the circuits that provide the electricity you require. Circuit breakers interrupt electrical power flow when there is danger. They protect the circuits. We’ll be discussing what circuit breaker panels do and when it’s time to upgrade or replace them.

You probably don’t think of this particular component very often, but it’s one of the most crucial components of your home’s electrical system. It’s known by the name of a circuit breaker or the breaker box.

This is important because all electricity that is used in your home runs through it, and through the circuit breakers. If it’s properly configured it won’t be a problem to think about it.

If it’s not adequate for the job It could be extremely difficult to manage or could cause safety concerns for your home.

This article will provide an explanation of what an electrical panel is and how it works. We’ll also look at some reasons why you might want the main panel for your breaker checked by a qualified electrician of LA Solar Group. Let’s start by understanding the basics of the circuit breakers.

What is a breaker panel and how does it work?

The circuit breakers connect the electrical grid outside your house to your wiring. This is the main service panel that regulates all electrical outlets, lighting, heating, and other devices.

Service drop can be described as a way through which power is delivered to the breaker box through the outside. This can be either from power poles or underground power lines. The electricity is then routed through branch circuits to power your home.

You should also be familiar with other names

“Breaker panel” is a name that refers to the circuit breakers which supply power to the branches leading to the panel. It can also be referred to by many different names. It may also be called the circuit breaker, breaker box, or electrical panel. It works in the same manner regardless of what it’s given.

How it works

Circuit breakers are crucial safety devices that cut off branch circuits in the event that they sense an overload. This is why you could be noticing a circuit breaker tripping (shutting down) after you plug in several appliances in your kitchen.

This fuse box has an earlier version in the event that you’re older and reside in an older home. Fuses’ purpose were to safeguard your branch circuits from overloads. A blown fuse is required to be replaced to restore power for the circuit. A circuit breaker can be reset by simply flipping a switch.

Capacity of the breaker box

Amperage capacity is probably the most crucial figure to be aware of regarding your panel. Amperage (or amps) is a measurement of how much electricity is utilized. The amperage capacity for the breaker panel in your home has increased as homes get larger and more electrical appliances are used. While 200-amp circuit breakers are standard nowadays however, you may find panels or fuse boxes with ratings as just 60 amps in houses built prior to 1960.

Where can I find my main fuse box?

It is possible that you are uncertain about where your breaker panel is situated if you’ve never had the opportunity to use it. There are a variety of common places.

Garages are often found in common areas. They’re usually positioned on the outside of a wall, in which power is supplied through the drop in service.

It’s not uncommon to see the panel for a breaker in a basement in the event of a buried powerline.

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

An exterior wall is not a common place which you may discover in older homes.

A look inside your electrical panel

Let’s get through the panel by opening the door.

It is impossible to see what you don’t know

The main breaker panel is within the box. There are some switches. Below are the hot and ground bus bars. Each individual switch you’ll see has its powered and ground wires routed to it.

Main switch

The panel’s top will have only one switch. This is the main breaker. This will turn off all power to your home.

Individual circuit switches

Two rows of number switch are among the very first things you find when you enter the panel’s door. These are the circuit breakers. Each one is responsible for the circuits in your home. The circuit breakers should be switched on to allow power to flow through them. Circuits will get shut out if the switch turned off.

A piece of paper with the details of the number can be found within the door’s door panel. The card may read “1 - Kitchen Outlets.” The switch can be turned on or off to shut off the electricity to your kitchen outlets.

It’s common to find the card not easy to understand or badly written. It’s worth spending some time with another person to review the switch controls and ensure that the card is clear and legible. This will allow you to understand how to shut off power to circuits such as if you need to replace 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 called single switches having an amperage rating between 15 and 20 amps. They are commonly used in household circuits with 120 volts.
  • Double-pole breaker is the double switch that has two switches that are connected. These are specifically designed to handle the voltage of 240 V and are equipped with higher amperage ratings. They can be connected with high-voltage circuits such as water heaters, furnaces, and air-conditioning.

The sub panel

You may find an additional panel next to the main box in some cases. You might have an outbuilding that you need to run on its own system, or you’ve made changes to the electrical system in your home. If a backup generator has been connected to the home’s electric system, then a sub-panel can be used.

The size that you need

There is a possibility of an article on the rating of breaker panels when you read up on panel upgrades and breaker panels. There are two most frequently discussed ratings being 100-amp or 200-amp. These ratings represent the power of the electrical panel.


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


These boxes are typical for new construction and are used for an average electrical requirement. You might require a larger panel box if your house requires more power or is extremely big.


These panels are great for large homes that have a lot of electrical requirements, especially if the electricity is utilized to heat the house. You might need to upgrade your existing panel to a 250-amp or greater model if you’re upgrading the electrical system within your home to accommodate an extension building, workshop, or other outbuilding.

Signs your current panel is not up to the job

It’s likely that you’ve had 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. This is a good example of your panel’s ability to do its job. If the issue isn’t occurring often, there’s nothing to worry about.

There are instances when it is not OK. These indicators could mean that your breaker panel is overloading or is not working properly. Let’s examine a few of these.

Frequent breaker tripping

A circuit breaker malfunction is not a an alarm signal. If any of the circuit breakers in your home need to be reset regularly, you may have a problem. Sometimes, the issue could be fixed easily by replacing it with a model of higher amperage. It is however, advisable to consult an electrician to ensure that this is possible.
