Pick by the clock

Pole count. Amps. Hour. One body.

A pin & sleeve plug is named by three facts: how many poles it carries, its amperage, and the hour position of its earth contact, which fixes the voltage and the colour. Answer the three, or type the code printed on the body, and we show the cell and what we have in it.

1 How many poles?

Pole count · amps · P plug / C connector / R receptacle / B inlet · hour · S splashproof or W watertight. A 320P6W is a 3-wire, 20 A plug with the earth at 6 o'clock, IP67.

Body code 320P5 · grey body

  • Earth contact at 5 o'clock: 277V. That position is the interlock; a 277V body cannot enter a socket keyed for another voltage.
  • Grey body: the standard's colour for 277V, so the voltage reads from across the room.
  • 2P+E: single phase.
  • 20 A is the North American rating (UL 1682 / c(UL)us); the same body is rated 16 A under IEC 60309-2. One part, two listings, never mixed in one range statement.
