Short circuits and overloads are abnormal conditions that cause heavy current flow in a circuit. Heavy currents are capable of damaging a device or a circuit and may end up…
Circuit protection devices such as fuses and MCBs are used to safeguard any equipment from damages caused due to short circuits. The usage of these devices does not mitigate the…
Relays are electrically operated switching devices, used to gain control over processes and circuits. Based on their principle of operation they are classified into two types: Solid-state relays and electromechanical…
Earth fault is an undesirable condition at which current flow from a conductor to earth. This can happen when a current-carrying conductor falls on the ground or the body of…
When a circuit breaker interrupts high currents, an electric arc is generated. An electric arc is the discharge of electric current through gas or air. The conduction of electric charges…
Power is transmitted over long distances at high voltage. In order to supply domestic and residential applications, it needs to be stepped down to 120V or 230V single phase. This…
Electrical engineers and electricians follow predefined wiring colour codes while wiring houses, commercial buildings and industrial panel boards. The electrical wiring colour codes followed is slightly different in every part…
In every control circuits and automation systems, logic is developed based on the open or closed state of switches, sensors or relays. Hence it is mandatory to know the concept…
kA rating of an MCB or an MCCB is the maximum current it can safely interrupt in case of a short circuit. If the current goes beyond this value, the…
MCB stands for miniature circuit breaker. It is a circuit protection device, capable of protecting a circuit or a piece of equipment from greater damages caused due to short circuits…
