Plot. J.D. ( Chuck Norris ), a trucker from California, returns from the road to learn that an old friend was assaulted and paralyzed by Sergeant Strode (Don Gentry), a policeman in Texas City, California. He makes inquiries into Texas City and learns that its policemen Strode and Deputy Boles (Ron Cedillos) have a history of "trapping ...
Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. 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.
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 ...
On the morning of 9 March, the S&P 500 fell 7% in four minutes after the exchange opened, triggering a circuit breaker for the first time since the financial crisis of 2007–08 and halting trading for 15 minutes.
Zinsco was a manufacturer of electrical distribution panels and circuit breakers, founded by Emile Martin Zinsmeyer and his son Martin Emile Zinsmeyer in the early 1930s.
An arc-fault circuit interrupter ( AFCI) or arc-fault detection device ( AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires. An AFCI selectively distinguishes between a harmless arc (incidental to ...
Assault Breaker was a Defense Advanced Research Projects Agency (DARPA) program begun in 1978 to integrate a number of technologies including lasers, electro-optical sensors, microelectronics, data processors and radars important for precision guided munitions (PGMs).
The industrial applications of high voltage circuit breakers are for the moment limited to alternating current because they are more economical, there are however high voltage disconnectors for direct current connections.
