2. Arc-fault circuit interrupter - Wikipedia

   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   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." 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 ...

3. Arc fault - Wikipedia

   en.wikipedia.org/wiki/Arc_fault

   Two types of wiring protection are standard thermal breakers and arc fault circuit breakers. Thermal breakers require an overload condition long enough that a heating element in the breaker trips the breaker off. In contrast, arc fault circuit breakers use magnetic or other means to detect increases in current draw much more quickly.

4. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   This device, which can be a circuit breaker or the first outlet on a circuit, is designed to detect hazardous electrical arcing in the branch circuit wiring as well as in cords and plugs. An AFCI device is designed to trip quickly when it detects potentially dangerous arcing that could start a fire, but not trip with harmless arcing as part of ...

5. National Electrical Code - Wikipedia

   en.wikipedia.org/wiki/National_Electrical_Code

   AFCI devices generally replace the circuit breaker in the circuit. As of the 1999 National Electrical Code, AFCI protection is required in new construction on all 15- and 20-amp, 125-volt circuits to bedrooms. [11]

6. Multiway switching - Wikipedia

   en.wikipedia.org/wiki/Multiway_switching

   The Carter system, also known as the Chicago system, was a method of wiring three-way switches in the era of early knob-and-tube wiring. This now-obsolete wiring method has been prohibited by the USA National Electrical Code since 1923, [ 2 ] even in new knob-and-tube installations which are still permitted under certain circumstances.

7. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A small circuit breaker typically has a manual control lever to switch the circuit off or reset a tripped breaker, while a larger unit may use a solenoid to trip the mechanism, and an electric motor to restore energy to springs (which rapidly separate contacts when the breaker is tripped).

   Donald Trump on Monday shared a ruthless highlight reel of Democrats in denial over Joe Biden's cognitive decline after a veteran journalist slammed US media for not making it a bigger story.

9. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   AFCI receptacles look similar to GFCI receptacles in that they have a "Test" and "Reset" button on the face of the device for localized testing. This saves a homeowner a trip to the breaker panel, should the device trip. Unlike AFCI breakers, AFCI receptacles can be used on any wiring system, regardless of the panel.
