How Circuit Breaker Works?
Circuit breaker is a device which prevents electric current from entering or leaving your home. A circuit breaker protects against electrical shock if there’s any shorted out wires inside the house. There are two types of circuit breakers: manual and automatic. Manual circuit breakers must be manually turned on and off to protect your home from potential power outage. Automatic circuit breakers are automatically activated when they detect abnormal voltage readings in the wiring system.
A circuit breaker can only open or close according to its safety requirements. If it detects that there’s no electricity present within the area where it operates, then it will not allow any current to flow through. However, if there is an overload of electricity in one particular location, then the breaker may open up allowing some excess energy into your home.
The most common type of circuit breaker is the wall receptacle circuit breaker. When a power surge occurs, such as during a lightning strike or an explosion, the receptacles in your home become overloaded with electricity causing them to explode into flames. These explosions cause damage to everything around them including yourself! The exploding devices are usually located near outlets where you plug in appliances like televisions and computers.
It’s very important to have a properly functioning breaker for these locations, but how do you know if your breaker works well enough?
Simple, just follow the instructions below:
Step 1: Check the Circuit Breaker Box
The main breaker box in your house is where the electrical supply originates. If you’re lucky then your house already has one installed! If there is already one in your house, then check if it’s properly labeled and operational. Most breaker boxes are labeled as “main” or “breaker box”.
If you can’t find any of these labels then try to find the main power switch. This is usually a very large switch on the main panel itself.
Step 2: Turn Off Power to the House
Before performing any work in your breaker box, you need to make sure that power is completely cut off from the entire house! To do this, simply flip all of the breaker switches to the “off” position. If you don’t do this then you may suffer from a potentially fatal shock! Now that the power is off, you can move on to performing your inspection.
How to Locate a Circuit Breaker
Most houses nowadays have very advanced breaker boxes with an abundant number of receptacles. In these boxes, locating a specific breaker can be a challenge if you don’t know what you’re doing.
