Industrial power inlet for wet locations

The Hubbell HBL320B4W is a watertight IEC pin-and-sleeve inlet rated 20 A at 125 V AC. Its IP67 housing and yellow finish suit industrial equipment that must stay powered in wash-down or outdoor environments. Single-phase, three-wire grounding meets IEC grounding style requirements.

Screw terminals accept 14 to 10 AWG conductors

The flanged inlet uses screw-terminal connections for solid or stranded wire from 14 AWG up to 10 AWG. A 1 hp motor rating allows direct connection of small industrial motors. The shrouded, grounded pins maintain polarity and safety when mated with a matching IEC connector.

Flange mount needs 2.72 in cut-out and four screws

Face diameter is 1.85 in and flange diameter is 2.72 in, so the panel cut-out must match that bolt circle. Moisture-resistant seals only work when the mating connector is fully seated and locked. Mis-wiring the three poles or exceeding the 20 A rating will trip upstream protection.

Questions about this item

How often should the screw terminals on this 20 A inlet be checked and retightened?

Inspect the screw terminals annually or after any vibration event; retighten to the manufacturer torque value to maintain a secure 10–14 AWG connection.

What is the continuous current limit before the 125 V inlet reaches its thermal rating?

The inlet is rated for 20 A continuous at 125 V AC; sustained loads above that will exceed the device thermal limit.

Does the IP67 housing add noticeable heat rise when the inlet runs at 20 A all day?

The IP67 watertight seal does not change the rated temperature rise; at 20 A the inlet stays within its designed thermal envelope.
