âIt all depends on whose ox is being goredâ is an old saying of uncertain origin â it may relate to an obscure verse in Exodus in the Holy Bible relating to compensation for the eponymous damaged cattle â but in wide use.n fact, they note that from 1992 to 1997, the U.S. trade deficit almost tripled, while at the same time U.S. industrial production increased by 24 percent and manufacturing output by 27 percent (See Griswold).
This AFCI (the circuit breaker with the yellow label) is an older generation AFCI circuit breaker. The current (as of 2013) devices are referred to as combination type and usually appear with a green label. An Arc Fault Circuit Interrupter (AFCI) is a type of duplex receptacle or circuit breaker that breaks the circuit when it detects a dangerous electrical arc in order to prevent electrical fires.
An AFCI is a product that is designed to detect a wide range of arcing electrical faults to help reduce the electrical system from being an ignition source of a fire. Conventional overcurrent protective devices do not detect low level hazardous arcing currents that have the potential to initiate electrical fires.hen arcing occurs, the AFCI analyzes the characteristics of the event and determines if it is a hazardous event. AFCI manufacturers test for the hundreds of possible operating conditions and then program their devices to monitor constantly for the normal and dangerous arcing conditions.
