2. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.

3. Three-prong adaptor - Wikipedia

   en.wikipedia.org/wiki/Three-prong_adaptor

   Note that an external GFCI receptacle tester may not make an ungrounded GFCI trip, as these testers use the ground connection to simulate a fault. But the test button integrated into the GFCI receptacle should function normally and cause the outlet to shut off until it is reset manually.

4. Bootleg ground - Wikipedia

   en.wikipedia.org/wiki/Bootleg_ground

   In addition, a fault condition to a bootleg ground will not trip a GFCI breaker, nor protect a receptacle that is wired from the load side of a GFCI receptacle. [2] Before 1996, in the United States it was common to ground the frames of large 120/240-volt permanently-connected appliances (such as a clothes dryer or oven) to neutral conductors.

5. 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).

6. 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 ...

   A fight broke out on the football field after the University of Michigan beat Ohio State University in a 13-10 upset on Saturday. Video of the incident showed players on the two rival teams ...

8. Single-wire earth return - Wikipedia

   en.wikipedia.org/wiki/Single-wire_earth_return

   The resistance may be high enough to affect self-resetting circuit breakers, which usually reset due to a difference in voltage between line and neutral. With dry, high-resistance soils, the reduced difference in voltage between line and neutral may prevent breakers from resetting.

   Donald Trump continues to threaten tariffs against foreign nations, this time toward a bloc of nine countries if they try to undermine the dollar's global dominance.
