Why Are Circuit Breakers So Useful?
Circuit breakers have been around for a long time but nobody really realises why all of these electrical components actually come in useful.
Brief History
The idea itself came from Edison in 1879 so the circuit breaker idea has actually been around for a very long time indeed. The master himself Edison wanted to protect circuits from short-circuiting and overloading.
What They Do
All circuit breakers have things in common and that doesnt matter on whether they are big or small it does depend on the voltage class of course.
The circuit breaker must detect a fault condition which is usually done within the breaker enclosure when it comes to the smaller circuit breakers. Once the fault has been found, contacts within the breaker will open up to stop the circuit. The current can be switched off manually on many of the smaller ones.
When the current is actually interrupted an arc is generated and this arc must then be contained, cooled and taken out in a controlled way. This means that the gap between contacts can continue to take the voltage of the circuit.
Saving Lives
So believe it or not these circuit breakers actually save thousands of lives every single year. The problem occurs when somebody starts to plug in items that simply should not be put into the same place. It could actually be very easy for a fire to start if too many appliances are plugged in to the same place. This fire could potentially then burn the entire house down which is something that can be avoided if you had that circuit breaker. The circuit breaker will cut off all of the power before a fire starts.
So although you may not think all of those mil spec cables are important it would seem that they are.
