How Do Circuit Breakers Work?

Any home or establishment running on electricity has at least one circuit breaker. When electricity flows into a building, it is divided into several circuits. Each of these circuits is safeguarded by breakers to prevent any tripping or short circuit that can damage electrical appliances or worse, can cause fire. Depending on the size of electrical appliances used in a room, the amperage for each circuit breaker may differ. For example, bedrooms that only use lights and other small appliances run on 15-Amp circuits. On the other hand, rooms that make use of larger appliances such as TVs, stoves, washing machines, dishwashers and the like require 20-Amp circuits.

Circuit Breakers Work in a System

The wires that run through the breaker, the breaker itself and the insulation all work as a team. Just a malfunction of one of these may result in dangerous situations. When you try to use more electricity than the circuit breaker is designed to receive, you can expect something bad to happen. When too much electricity runs through a wire, its insulation melts. The insulation acts as a barrier or a protection where electricity should course through. If the insulation is damaged, the electricity is no longer confined in the wires, which can start fires.

Choosing the Appropriate Breaker

You can look at websites like to look at circuit breakers that will suit your needs. You should enlist the services of a qualified electrician in installing a circuit breaker to make sure that installation is done according to industry standards and regulations.

Tampering with Circuit Breakers

Tampering with circuit breakers is a common practice among households. Little do homeowners know that doing this can cause a catastrophic situation. If the circuit breaker cannot work properly in interrupting the flow of electricity when there is too much flowing into the wire, the insulation will melt and cause a fire.


Overloading happens when the amount of electricity that courses through the wires is a lot more than the required amount that should run through them. When there are too many electrical appliances running at the same time, the circuit breaker may not be able to handle all the electricity that flows through it.

Choosing the right circuit breaker for your electricity consumption is paramount; make sure that the right amp-rating is used. If you are not experienced with such tasks, enlist the services of a qualified electrician. Working with electricity should be done with utmost care. A lot of accidents happen due to short-circuiting of wires, overloading and the like. It is also important to note that electrical safety can be achieved by following regulations to a T. They are formulated for the purpose of ensuring safety for everyone who makes use of electricity.
