  2. Pad-mounted transformer - Wikipedia

    en.wikipedia.org/wiki/Pad-mounted_transformer

    Pad-mount transformers have self-protecting fuses consisting of a bayonet mount fuse placed in a high voltage compartment, with a backup high energy current limiting fuse in series to protect against secondary faults and transformer overload. The bayonet mount fuse protects against secondary faults and transformer overload and is a field ...

    en.wikipedia.org/wiki/Multiway_switching

    These switches appear externally similar to single pole, single throw (SPST) switches, but have extra connections which allow a circuit to be controlled from multiple locations. Toggling the switch disconnects one "traveler" terminal and connects the other. Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. By ...

    en.wikipedia.org/wiki/Fuse_cutout

    In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...

  7. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    In this case, single-phase distribution transformers are used. [5] The number of customers fed by a single distribution transformer varies depending on the number of customers in an area. Several homes may be fed from a single transformer in urban areas; depending on the mains voltage, rural distribution may require one transformer per customer.
