With single-phase sockets (T11, T13, T21, T23) the protective collar is 13 mm (+5 mm) deep, with three-phase sockets (T15, T25) 17.5 mm (+1 mm) deep. Dimensions of the connector Plugs according to T11 and T21 are between 13 mm and 14.5 mm wide, those according to T13 and T23 between 14.5 mm and 20 mm wide.
The Type 2 connector has a maximum power output for 43 kW and can handle both single-, dual- and three-phase AC power. The IEC 62196-2 Type 1 connector (codified under SAE J1772) is the corresponding standard for single-phase AC charging in the United States, Canada, and South Korea. [12] J1772 has a maximum output of 19.2 kW. [13]
This allows one to choose single-phase AC power at either 110–120 volts between phase and neutral or 220–240 volts between phase and phase. Since these two modes do not need three phases there is also a dark yellow-orange four-pin connector available designed for a single-phase 110–120 or 220–240 volt load.
Plugs are available in P+N+E (unbalanced single phase with neutral), 2P+E (balanced single phase), 3P+E (3 phase without neutral), and 3P+N+E (three phase with neutral). Current ratings available include 16 A, 32 A, 63 A, 125 A and 200 A. Voltage rating and other characteristics are represented by a colour code (in three-phase plugs the stated ...
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 socket is rectangular, with lateral key pins and indentations to maintain polarisation, and to prevent insertion of a plug with different current ratings. Three single-phase general purpose connectors were rated 10 A, 16 A and 20 A; and a three-phase industrial connector rated 10 A; all of them have different key-pin positioning so plugs ...
The numerals preceding the hyphen encode the number of poles (current-carrying terminals) and wires connected to it, the voltage, and single- or three-phase power. [citation needed] A connector with ground terminal has more wires than poles: two-pole, three-wire; or four-pole, five-wire; etc.
Given that a 480Y/277 VAC three-phase wye-connected four-wire supply is a common configuration supplied by utilities at commercial locations – under SAE J3400 and SAE J3068 the implied higher rating is taken; thus allowing single-phase charging at 277 VAC nominal for North American application.
