Switch to safety now with electrical switchgear

Imagine having all the appliances you need but not having the switches to plug them in! Switches and switchgear are an integral part of our homes not because of their function but their convenience. And with great power comes great responsibility. Needless to say, switchgear should be extremely safe to use because this type of equipment is directly linked to the reliability of the electricity supply. Switchgear and protection go hand in hand. The earliest known power stations used simple switches, mounted on insulating panels of marble or asbestos. When power levels and voltages rapidly escalated, making opening manually operated switches were too dangerous for anything other than isolation of a de-energized circuit. Today, those days are long gone. We now see switchgear that not only protects but complements the place you live in. These are the days of aesthetically designed switchgear that raises your room’s style quotient as well. In technical terms, these days we see every...

What causes electrical circuit breakers to trip?

Consider there were no circuit breaker trips, then wouldn’t house fires be a common issue? The circuit breaker usually trips when there is too much electricity flows through it or when it cannot handle the excess current load. This implies that the flow of electricity is cut off to keep circuits from overheating or causing more damage. Therefore, it is important that we pay special attention to the electrical circuit breakers including miniature circuit breakers as well. Even though the tripping of circuit breakers ensures safety, it can get quite annoying to constantly experience them and getting the power back on repeatedly. Thus, let us look at the three main reasons that cause circuit breakers to trip: Circuit Overloads:   An overload is the primary reasons behind the tripping of electrical circuit breakers constantly. This occurs when we want a particular circuit (example, miniature circuit breaker) to provide more electricity than its actual capacity. This leads to o...
