Hubbell Series 16 400 A Female Receptacle

The Hubbell Series 16 single-pole female receptacle accepts cable sizes from 4 AWG to 4/0 AWG and is rated up to 400 A at 600 V AC or 250 V DC. It uses a double set-screw terminal for secure conductor retention and mounts through a panel with threaded hardware. The yellow thermoplastic elastomer housing and brass contacts suit indoor dry locations and NEMA 12, 3R, and 4X enclosures.

Sustained load performance

The device carries a continuous 400 A rating (300/400 A AC/DC) under the UL 1691 standard, so it handles prolonged high-current duty without derating for short bursts. Brass contacts and the double set-screw design maintain low resistance over repeated thermal cycles. The thermoplastic elastomer housing resists heat and environmental exposure in listed enclosure types.

Pre-installation checks

Verify that your panel cut-out and hardware match the through-hole mounting pattern and that the enclosure meets NEMA 12, 3R, or 4X requirements for the intended environment. Confirm the cable falls within the 4 AWG to 4/0 AWG range and that the circuit voltage does not exceed 600 V AC or 250 V DC. Installation must follow ANSI/NFPA 70 (NEC) guidelines.

Questions about this item

Does the 400 A rating mean the HBLFRY receptacle runs hot during continuous all-day use?

The receptacle is rated for 400 A at 600 V AC or 250 V DC; heat rise depends on cable size, ambient temperature and enclosure ventilation — follow NEC ampacity tables for the conductor you install.

What cable and tools must I already have to terminate the double set-screw terminals on this panel-mount receptacle?

You need 4 AWG to 4/0 AWG copper cable, a torque wrench or driver calibrated to the manufacturer’s set-screw specification, and standard hand tools for the through-hole panel mounting hardware.

Will this Series 16 female receptacle mate with older Series 16 male plugs I already own?

Yes — Series 16 devices are designed to intermate; the taper nose and 400 A rating match legacy Series 16 plugs, so existing cables with the same series designation will connect without adapters.
