Single-phase 480 V equipment such as welders, heaters and process machines needs a receptacle that won't accept a lower-voltage plug and stays sealed in wet areas. The Techspan SCM320R7W is a 20 A, 480 VAC, 2-pole 3-wire IEC 60309 pin and sleeve receptacle from the Eureka-HD series, colour-coded red with the ground at 7 o'clock. It is IP67 watertight and interchangeable with other makers' 320P7W plugs.
Why industrial electricians pick it
- Red 7h keying for 480 V keeps 120 V, 240 V and three-phase plugs out.
- IP67 watertight for washdown, outdoor and wet plant locations.
- Valox housing, nickel-plated brass contacts and neoprene seals.
- Terminals take #14 to #10 AWG conductors.
- UL and cULus listed; IEC 60309 interchangeable with any 320P7W plug.

Pro tip from the counter
A 2-pole 3-wire 480 V device is fed line-to-line from two phases plus the bonding conductor, with no neutral terminal. Have your electrician run it from a 2-pole breaker, and don't use it for 277 V line-to-neutral equipment, which needs a different configuration.
Best for: 480 V single-phase welders and heaters, process and packaging equipment, washdown and wet plant areas, industrial maintenance outlets
