Angled Back Box for IEC 309 Devices

The Hubbell BB2030N is a non-metallic, 15-degree angled back box designed for surface mounting in industrial environments. It accepts one IEC 309 Pin & Sleeve or Twist-Lock receptacle or inlet rated for 20 or 30 amps. The thermoplastic construction provides an IP67 and NEMA 4X enclosure rating for watertight and corrosion-resistant performance. Mounting screws are included for installation.

Capacity and Headroom

This back box accommodates 20A and 30A watertight safety shroud devices, covering the standard industrial pin-and-sleeve range. It supports a single device per unit, so installations requiring multiple receptacles will need additional boxes. The 1-inch NPT hub provides a single cable entry point; setups needing multiple conduit runs cannot be served by this housing alone.

Thermals Noise and Power Draw

As a passive wiring accessory, the box draws no power and generates no operational noise. The non-metallic thermoplastic material does not act as a heatsink, so thermal management depends entirely on the installed device and ambient conditions. The IP67 rating ensures the enclosure maintains integrity against dust and water ingress during normal industrial use.

Questions about this item

Will the 15° angled back box fit the IEC 309 Twist-Lock receptacle I already own?

The box accepts one IEC 309 Pin & Sleeve or Twist-Lock device rated 20 or 30 amps, so your existing receptacle will mount directly.

How can I confirm the IP67 seal is effective after installation?

Verify the 1" NPT hub is tightened, the device gasket seats fully, and the mounting screws compress the enclosure evenly against the surface.

Does the package include the receptacle and cable gland or only the back box?

The box ships with mounting screws only; the IEC 309 Pin & Sleeve or Twist-Lock device and a 1" NPT cable gland must be purchased separately.
