  2. High-leg delta - Wikipedia

    en.wikipedia.org/wiki/High-leg_delta

    So if A–B, B–C and C–A are all 240 volts, then A–N and C–N will both be 120 volts, but B–N will be 208 volts. Other types of three-phase supplies are wye connections, ungrounded delta connections, or corner-grounded delta [2] (ghost leg configuration) connections. These connections do not supply split single-phase power, and do not ...

  3. Split-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Split-phase_electric_power

    The neutral conductor is connected to ground at the transformer center tap. Circuits for lighting and small appliance power outlets use 120 V circuits connected between one line and neutral. High-demand applications, such as ovens, are often powered using 240 V AC circuits—these are connected between the two 120 V AC lines.

  4. Electrical wiring in North America - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring_in_North...

    Lighting and general purpose receptacles are at 120 volts AC, with larger devices fed by three wire single-phase circuits at 240 volts. In commercial construction, three-phase circuits are often used. Common 3 phase configurations within a building are 208v/120 wye, 120/240 center tapped delta and 480v/277v wye. Lighting is usually fed by 277 V ...

  5. Three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Three-phase_electric_power

    Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]

    120 V 240 V 240 V 120/208 V 277/480 V 120/240 V 240 V 480 V 60 Hz NEMA 5-20R outlets, which are similar to type B but have a T-shaped neutral slot, are sometimes used for higher current 120 V equipment (up to 20 A). U.S. Virgin Islands: A B NEMA 1-15P NEMA 5-15P 110 V 190 V 60 Hz Uruguay: C, F, I, L 230 V 400 V 50 Hz

  7. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    Most of the Americas use 60 Hz AC, the 120/240 volt split-phase system domestically and three phase for larger installations. 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.

  8. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...

  9. Mains electricity - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity

    This standard established 120 volt nominal system and two ranges for service voltage and utilization voltage variations. [18] Today, virtually all American homes and businesses have access to 120 and 240 V at 60 Hz. Both voltages are available on the three wires (two "hot" legs of opposite phase and one "neutral" leg).
