  2. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    North American transformers usually power homes at 240 volts, similar to Europe's 230 volts. It is the split-phase that allows use of 120 volts in the home. Japan's utility frequencies are 50 Hz and 60 Hz. In the electricity sector in Japan, the standard voltage is 100 V, with both 50 and 60 Hz AC frequencies being used.

  3. Utility pole - Wikipedia

    en.wikipedia.org/wiki/Utility_pole

    Typical North American utility pole, showing hardware for a residential 240/120 V split-phase service drop: (A,B,C) 3-phase primary distribution wires (mounted on a crossarm), (D) neutral wire, (E) fuse cutout, (F) lightning arrestor, (G) single-phase distribution transformer, (H) ground wire to transformer case, (J) "triplex" service drop ...

  4. Electrical wiring in North America - Wikipedia

    Leg as in "hot leg" refers to one of multiple hot conductors in an electrical system. The most common residential and small commercial service in Canada and the U.S., single split-phase, 240 V, features a neutral and two hot legs, 240 V to each other, and 120 V each to the neutral. The most common three-phase system will have three hot legs ...

  5. 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 ...

  6. Split-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Split-phase_electric_power

    120 V circuits are the most common, and used to power NEMA 1 and NEMA 5 outlets, and most residential and light commercial direct-wired lighting circuits. 240 V circuits are used for high-demand applications, such as air conditioners, space heaters, electric stoves, electric clothes dryers, water heaters, and electric vehicle charge points.

  7. Mains electricity - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity

    It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world. People use this electricity to power everyday items (such as domestic appliances, televisions and lamps) by plugging them into a wall outlet. The voltage and frequency of electric power differs between regions. In ...

    The 16 amp version uses wider pin spacing and larger pins. Hybrid outlets that accept both types are common and some also accept type F. NB: 16 amp type C plugs, such as CEE 7/17 commonly found on hairdryers, will not fit type L outlets and need an adapter, or should be used with a type F or hybrid type L/F outlet. Jamaica: A, B 110 V

  9. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    The other end of the three secondary windings and the neutral are brought down the service drop to the service panel. 230 V loads are connected between any of the three-phase wires and the neutral. Because the phases are 120 degrees from each other, the voltage between any two phases is sqrt(3) * 230V = 400V, compared to the 2 * 120V = 240V in ...
