Like any other repair or improvement project around the house, electrical work does require tools. Not only do these tools increase efficiency but they also provide safety to the user. Let's talk about how picking the...

Overcurrent protection is critical to personal safety and protection from a number of hazardous conditions that can result from materials igniting. Short-circuits can result in arc-flashes, which can cause severe burns...

A synchronous condenser is a synchronous motor running at no load and in over-excited mode. A synchronous motor in over-excited mode behaves as...

Cable selection is about choosing the appropriate type of conductor and selecting a suitable size/cross-section area/ diameter of the conductor according to the application. First, there is a need to understand the...

Formerly known as Underwriters Laboratories (UL), this was a non-profit organization but now it has transformed into UL LLC, a for-profit internationally accepted safety organization located in the United States and...

A circuit breaker is a power system protection device that can make or break a circuit

A circuit breaker operates under fault conditions and isolates the faulty part of the circuit from the rest of it by breaking the...

Arc Flash incident is one of the most dangerous hazards faced by electricians all over the world. According to statistics, 5 to 10 arc flash explosions occur in electric equipment every day in the United States.
