Electrical breakers are essential to any electrical system, as they protect homes and businesses from electrical overloads and short circuits.
This article will explain what electrical breakers are, how they work, and the different types of breakers available in the market.
What are Electrical Breakers?
Electrical breakers are safety devices that protect electrical systems from damage caused by excessive current. They are installed in electrical panels and are designed to automatically shut off power when a circuit becomes overloaded or experiences a short circuit. This helps prevent fires, electrical shocks, and other hazards.
How Do Electrical Breakers Work?
Electrical breakers use a mechanism that detects and interrupts electrical current when it exceeds safe levels. This mechanism typically consists of a bimetallic strip that expands and contracts when heated and a tripping mechanism that releases the switch to shut off power to the circuit.
When the current exceeds the safe limit, the bimetallic strip heats up, causing it to bend and trip the switch. This interrupts the flow of current and prevents damage to the electrical system.

Types of Electrical Breakers:
There are several types of electrical breakers available in the market. Here are some of the most common types:
Standard Circuit Breakers:
- Standard circuit breakers are the most common type of breakers used in homes and businesses. They are designed to protect circuits from overloading and short circuits. Standard circuit breakers come in a range of sizes, ranging from 15 amps to 200 amps, and can be either single-pole or double-pole breakers.
Single-pole breakers are designed to protect 120-volt circuits, while double-pole breakers are used for 240-volt circuits, such as those used for large appliances like air conditioners and electric water heaters.
Ground Fault Circuit Interrupters (GFCIs):
- Ground Fault Circuit Interrupters (GFCIs) are designed to protect people from electrical shocks. They monitor the flow of current and shut off power when they detect a ground fault or leakage.
GFCIs are commonly used in areas where water and electricity can come into contact, such as bathrooms, kitchens, and outdoor areas. GFCIs can be installed as a circuit breaker in an electrical panel or as a standalone outlet.
Arc Fault Circuit Interrupters (AFCIs):
- Arc Fault Circuit Interrupters (AFCIs) are designed to protect against fires caused by arcing faults. They detect arcs in the circuit and shut off power before they can ignite a fire.
Arc faults can occur when a loose or damaged wire is in a circuit, causing sparks to jump across the gap. AFCIs are required by the National Electrical Code (NEC) in certain areas of the home, such as bedrooms, living rooms, and dining rooms.
Dual Function Circuit Breakers:
- Dual Function Circuit Breakers combine the features of GFCIs and AFCIs. They protect against both electrical shocks and fires. Dual-function circuit breakers are a great solution for homeowners who want to upgrade their electrical systems without having to install separate GFCIs and AFCIs.
They are typically more expensive than standard circuit breakers, but they provide additional protection and can be a worthwhile investment for homeowners concerned about electrical safety.
High Amp Circuit Breakers:
- High amp circuit breakers are designed to protect large electrical equipment, such as generators, large motors, and industrial machinery.
These circuit breakers can handle currents of up to several thousand amps and are available in both thermal-magnetic and electronic trip versions. High amp circuit breakers are commonly used in industrial and commercial applications.
Understanding the different types of electrical breakers available can help you make informed decisions regarding protecting your home or business from electrical hazards.
