General Question About Circuit Breaker

Circuit Breaker

A Circuit Breaker is a protection device and it will trip automatically when there is any fault in load side. We all have at list one circuit breaker at our home and in an industry you will find different type of circuit breaker with different name. Some circuit breaker has a specific place where it will use. In this article we will learn why we need circuit breaker, how it works, why it trip and how to reset? But at first…

Where I Can Find Circuit Breakers?

All Breakers are found in your home’s breaker box. Generally a breaker boxes can be found in the garage, utility, basement and hall. Just look around and let us know where it is in comment.

Why We Need Circuit Breaker?

Home electrical appliance and electronic need electricity to power up. But some time poor wiring can causes overflow of current and wire become so hot then it started to melt and causes spark. In this case a circuit breaker helps to disconnect the load and prevent further damage. All circuit breaker has specific ampere rating. That’s means you have to calculate total amount of current before you install a circuit breaker.

How a Circuit Breaker Works?

In general, each circuit breaker is designed to ‘trip,’ or shut itself off at predetermined amperage loads. For example you have a pump which takes 5 ampere of current. But you install a breaker which maximum current rating is 4 ampere. That’s means your breaker will trip automatically when you switch on the pump. Same like for electrical short circuit. When it happens large amount of current flow through the circuit breaker and when it crosses the maximum limit of current then breaker will trip automatically.

Common Reasons Circuit Breakers Trip:

Normally an overloaded circuit can causes breaker to trip. For example your home is 10 years old. When you built your home that time you calculate that you need maximum 8 ampere of current when all home appliance is operational. For this reason you install a 10 ampere circuit breaker. But today you bought a new Electric Vehicle (EV) and you want to charge it at home. Let’s consider your EV will take 4 ampere of current when it’s charging. Now your total amount of current is 12 ampere which is 2 ampere higher than your present breaker. So you breaker will each time when you charge you EV. There are some others reason like short circuit, line to line fault, line to ground fault.

How to Reset A Circuit Breaker?

Suddenly if you lose power to an outlet or area of your home means a breaker may have been tripped. Now you have find out which breaker has tripped. But at first you have to reach breaker box. Once you reach to your breaker box, resetting the breaker is easy. You just need to open the door to the breaker box and look for the toggles. Most breakers should be pointing toward the panel center, indicating the ON position. Toggles pointing away from the panel center are OFF. Toggles in an in-between position are the one(s) which have tripped. Now you must turn OFF the breaker before turning it ON again. Without this operation breaker will not reset. Here one thing is important. The breaker was tripped means, there were some reason. Make sure you solve the problem before you turn it ON.
