An earth-leakage circuit breaker ( ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use residual ...

As commanding general, Grant led the Union Army to victory in the American Civil War in 1865 and briefly served as U.S. secretary of war.
Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, SF 6 circuit breakers are widely ...
In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and high-voltage circuit-breakers. Separation of the electrical contacts results in a metal vapour arc, which is quickly extinguished.
A circuit breaker triggered by unequal currents in live and neutral wires (i.e., electrical power is passing to earth). Mandatory for most circuits as of 17th Edition regulations. Residual current circuit breaker with overcurrent protection (RCBO) Combination of RCD and MCB; breaks circuit on being triggered either as an RCD or by overcurrent ...
The Chicago Street Course is a 2.2 mi (3.5 km) street circuit in Grant Park in the city of Chicago, Illinois, United States. It currently hosts the NASCAR Cup Series and NASCAR Xfinity Series, with the first races run on July 1–2, 2023. The track was initially a conceptual track on iRacing made for the eNASCAR iRacing Pro Invitational Series ...
