  2. Fuse (electrical) - Wikipedia

    en.wikipedia.org/wiki/Fuse_(electrical)

    Normal fast-blow fuses are the most general purpose fuses. A time-delay fuse (also known as an anti-surge or slow-blow fuse) is designed to allow a current which is above the rated value of the fuse to flow for a short period of time without the fuse blowing. These types of fuse are used on equipment such as motors, which can draw larger than ...

  3. Fuse cutout - Wikipedia

    en.wikipedia.org/wiki/Fuse_cutout

    The fuse element, or "fuse link", is the replaceable portion of the assembly that melts and breaks the circuit when the electric current through it exceeds its rated current value. There are many types of fuse elements for many different uses such as a type T fuse also known as a "slow-blow fuse" being used for sidelines.

  4. Electrical fault - Wikipedia

    en.wikipedia.org/wiki/Electrical_fault

    An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker. In three-phase systems, a fault may involve one or more phases and ground, or may occur only between phases. In a "ground fault" or "earth fault", current flows into the earth.

  5. Knob-and-tube wiring - Wikipedia

    en.wikipedia.org/wiki/Knob-and-tube_wiring

    Modern home buyers often find that existing K&T systems lack the capacity for today's levels of power use. First-generation wiring systems became susceptible to abuse by homeowners who would replace blown fuses with fuses rated for higher current. This overfusing of the circuits subjects wiring to higher levels of current and risks heat damage ...

  6. IEC 60269 - Wikipedia

    en.wikipedia.org/wiki/IEC_60269

    In electrical engineering, IEC 60269 is a set of technical standards for low-voltage power fuses. [1] The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices.

  7. Antifuse - Wikipedia

    en.wikipedia.org/wiki/Antifuse

    An antifuse is an electrical device that performs the opposite function to a fuse.Whereas a fuse starts with a low resistance and is designed to permanently break or open an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance--an open circuit--and programming it converts it into a permanent electrically ...

  8. Cylinder fuse - Wikipedia

    en.wikipedia.org/wiki/Cylinder_fuse

    A cylinder fuse is a type of electrical fuse.Like other types of fuses, it is a safety device used to protect electrical devices from excessive current. [1] [2]As its name suggests, a cylinder fuse is shaped like a cylinder.

  9. Service drop - Wikipedia

    en.wikipedia.org/wiki/Service_drop

    From there they pass through the wall of the house to the electric panel and Main Fuses or Circuit Breakers inside. In North America, the 120/240 V split phase system is used for residential service drops. [3] [4] A pole-mounted single phase distribution transformer usually provides power for one or two residences. The secondary winding of the ...
