NEMA wiring devices are made in current ratings from 15 to 60 amperes (A), ... 120/208/240 V service 277/480 V service ... 5-30 also has an L-shaped neutral blade. [17]
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]

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 ...
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 ...

120×570mm NATO tank ammunition (4.7 inch), also known as 120×570mmR, is a common, NATO-standard (STANAG 4385), tank gun semi-combustible cartridge used by 120mm smoothbore guns, superseding the earlier 105×617mmR cartridge used in NATO-standard rifled tank guns.
