What is a circuit breaker and what does it do?
A circuit breaker is an electrical safety device designed to protect a building’s electrical system. It works by monitoring and regulating the amount of current that passes through it. When the current reaches a predefined limit, the circuit breaker automatically shuts off, ceasing the flow of electricity and eliminating the risk of shortages, overloads or any other kind of malfunction. In effect, a circuit breaker serves as an extra layer for safety for your home’s power supply, making sure that you don’t experience any dangerous electric shocks or short circuits due to high electrical loads.
What is circuit breaker in simple words?
A circuit breaker is an incredibly useful, yet simple device. It basically acts like a switch, allowing electricity to pass through the circuit until it reaches a certain capacity — when it does, the circuit breaker ‘breaks’ or shuts off the power to prevent damage to the wiring or potential shock hazards. This is especially great for preventing fires caused by electrical overloads. In other words, it’s an economical and safe way to protect any electrical system from overload-related problems. A little bit of forethought can go a long way in terms of safety and making sure your home or office remains free (and properly) powered at all times!
Types of Circuits
Circuits are arrangements of electrical components that allow electricity to flow through in a predetermined manner, usually performing some type of function or tasks. Circuits can be powered with either direct current (DC) or alternating current (AC). Common circuit designs range from simple applications such as single LED light displays to complex integrated circuit boards found in computers, phones, and other electronics.
In many cases, the circuit design needs to accommodate a wide variety of different voltage sources and still function correctly at any given voltage level. Any typo of application requiring a steady current draw can take advantage of the efficiency and power available through a properly designed circuit.
What Happens When a Circuit Trips?
When a circuit trips, it stops sending power to the electrical device that is connected to it. Electrical current will cease to flow through the connection and any lights or appliances using this particular circuit will become inoperable. It is a safety mechanism designed to prevent potential overloads or short circuits that could cause damage or a fire hazard. When a circuit trips, users should investigate the cause before resetting it. In some cases, the issue may be fixable by resetting the breaker or switching off affected devices but if issues cannot be detected easily then professional help may be needed.
The difference between single and double pole circuit breakers
Single pole circuit breakers are generally used to protect a single 120-volt branch circuit, while double pole circuit breakers can be used to protect two separate 120-volt circuits or one 240 volt circuit. Both types of breakers provide the same protection from overcurrent and short circuits, but double pole breakers offer more flexibility for larger circuits such as those found in homes with major appliances like water heaters and air conditioners. Because of their flexibility and increased amperage ratings, double pole circuit breakers are typically preferred over single poles for residential applications.
