Three-phase electric power transmission lines Three-phase transformer (Békéscsaba, Hungary): On the left are the primary wires, and on the right are the secondary wires. In a symmetric three-phase power supply system, three conductors each carry an alternating current of the same frequency and voltage amplitude relative to a common reference ...
Since some wiring may be reversed, which would make motors turn backward, many machines on construction sites feature a phase swap plug that allows the L2 and L3 phase pins to be swapped, thereby reversing the phase sequence. Three-phase electric motors do not need the neutral wire to function, so that there is also a red four pin variant (3 ...
The connector is circular in shape, with a flattened top edge; the original design specification carried an output electric power of 3–50 kW for charging battery electric vehicles using single-phase (230V) or three-phase (400V) alternating current (AC), with a typical maximum of 32 A 7.2 kW using single-phase AC and 22 kW with three-phase AC ...
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 ...
The type 25 plug and socket has 3 rectangular pins, 4 mm x 5 mm, plus 2 flat pins (for L2 and L3). It is designed for three phase applications and is rated at 16 A, 250 V/440 V. The socket will accept types 11, 12, 21, and 23 single phase plugs, the Europlug, and types 15 and 25 three phase plugs. Swiss multi-phased sockets
In 1999, the Commissione Italiana Veicoli Elettrici Stradali [] (Italian electric vehicles association, CIVES) approached Scame to design an interface specifically for charging electric vehicles, [2] which led to a system that delivered single-phase AC line voltage through what is now called a Type 3A female socket via an adaptor that plugged into a standard 230 V AC outlet.

Again, the three-phase power socket is compatible with single-phase plugs, either of 10 A or 16 A ratings: [55] The type 25 plug has three rectangular pins of the same dimensions as type 23, plus two rectangular pins of the same dimensions as type 15. The corresponding type 25 socket is recessed and will accept plugs of types 11, 12, 15, 21, 23 ...
