  2. Utility pole - Wikipedia

    en.wikipedia.org/wiki/Utility_pole

    A pair of shoes can be seen hanging from the wires (center-left, far right) A utility pole is a column or post, usually made out of wood or aluminum alloy, [ 1 ] used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and street lights.

  3. Electrical load - Wikipedia

    en.wikipedia.org/wiki/Electrical_load

    An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1][2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power.

  4. Load profile - Wikipedia

    en.wikipedia.org/wiki/Load_Profile

    In electrical engineering, a load profile is a graph of the variation in the electrical load versus time. A load profile will vary according to customer type (typical examples include residential, commercial and industrial), temperature and holiday seasons. Power producers use this information to plan how much electricity they will need to make ...

  5. AC power plugs and sockets - Wikipedia

    en.wikipedia.org/wiki/AC_power_plugs_and_sockets

    The type 12 socket has no recess, while the type 13 socket is recessed. Both sockets will accept type 11 and type 12 plugs, and also the 2.5 A Europlug. Earlier type 11 & 12 plugs had line and neutral pins without sleeved pins, which present a shock hazard when partially inserted into non-recessed sockets. The IEC type J designation refers to ...

  6. AC power - Wikipedia

    en.wikipedia.org/wiki/AC_power

    In a simple alternating current (AC) circuit consisting of a source and a linear time-invariant load, both the current and voltage are sinusoidal at the same frequency. [3] If the load is purely resistive, the two quantities reverse their polarity at the same time. Hence, the instantaneous power, given by the product of voltage and current, is ...

  7. Aluminum building wiring - Wikipedia

    en.wikipedia.org/wiki/Aluminum_building_wiring

    Aluminum building wiring is a type of electrical wiring for residential construction or houses that uses aluminum electrical conductors. Aluminum provides a better conductivity-to-weight ratio than copper, and therefore is also used for wiring power grids, including overhead power transmission lines and local power distribution lines, as well ...

  8. Utilization categories - Wikipedia

    en.wikipedia.org/wiki/Utilization_categories

    Usually utilization category is mentioned in most of the switch gear, with the above contactor stating to be used under AC1 - resistive load & AC3 for motor usage. In electrical engineering utilization categories are defined by IEC standards [1] and indicate the type of electrical load and duty cycle of the loads to ease selection of contactors ...

  9. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    The demand, or load on an electrical grid is the total electrical power being removed by the users of the grid. The graph of the demand over time is called the demand curve. Baseload is the minimum load on the grid over any given period, peak demand is the maximum load. Historically, baseload was commonly met by equipment that was relatively ...
