    Microwave. 4. Microwaves. ... Using a power strip could cause the vacuum to underperform, have less suction and possibly trip a breaker. The sump pump and floor drains during installation.

  3. Crowbar (circuit) - Wikipedia

    en.wikipedia.org/wiki/Crowbar_(circuit)

    Once triggered, they depend on the current-limiting circuitry of the power supply or, if that fails, the blowing of the line fuse or tripping the circuit breaker. The name is derived from having the same effect as throwing a crowbar over exposed power supply terminals to short the output.

  4. Circulator - Wikipedia

    en.wikipedia.org/wiki/Circulator

    ANSI and IEC standard schematic symbol for a circulator (with each waveguide or transmission line port drawn as a single line, rather than as a pair of conductors). In electrical engineering, a circulator is a passive, non-reciprocal three- or four-port device that only allows a microwave or radio-frequency (RF) signal to exit through the port directly after the one it entered.

  5. Selectivity (circuit breakers) - Wikipedia

    en.wikipedia.org/wiki/Selectivity_(circuit_breakers)

    Selectivity, also known as circuit breaker discrimination, is the coordination of overcurrent protection devices so that a fault in the installation is cleared by the protection device located immediately upstream of the fault. The purpose of selectivity is to minimize the impact of a failure on the network.

  6. Circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Circuit_breaker

    A shunt-trip unit appears similar to a normal breaker and the moving actuators are ganged to a normal breaker mechanism to operate together in a similar way, but the shunt trip is a solenoid intended to be operated by an external constant-voltage signal, rather than a current, commonly the local mains voltage or DC. These are often used to cut ...

  7. Recloser - Wikipedia

    en.wikipedia.org/wiki/Recloser

    Automatically closing the breaker after it has tripped and stayed open for a brief amount of time, usually after 1 to 5 seconds, is a standard procedure. [ 5 ] Reclosers are often used as a key component in a smart grid , as they are effectively computer controlled switchgear which can be remotely operated and interrogated using supervisory ...

    Putting a non-microwave-safe material in a microwave oven can lead to chemicals leaching into your food (not good) or the melting of the container, which can lead to burns — or, at the very ...

  9. 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 ...
