OVERVIEW

Reliable Industrial Power Connection

The Hubbell HBL21414B Hubbellock® Connector Body is a premium-grade electrical connector designed to withstand the rigors of heavy industrial environments. Engineered for safety and durability, this 30 Amp, 600 Volt AC connector features Hubbell's proprietary Hubbellock® twist-lock mechanism. Unlike standard straight-blade plugs that can easily vibrate loose or be pulled out accidentally, this device ensures a positive, secure mechanical lock that maintains power continuity even in high-traffic areas.

Constructed with a tough nylon housing, the HBL21414B is built to resist impact, abrasion, and chemical exposure common in manufacturing plants and maintenance facilities. The 3-Pole, 4-Wire Grounding configuration provides essential safety for operating three-phase equipment or high-voltage machinery. Inside, the box terminals are designed for high conductivity and low heat generation, ensuring that your equipment runs efficiently without the risk of connection burnout.

Installation is straightforward thanks to the spacious wiring chamber and clear terminal markings. The integral cord grip offers robust strain relief, protecting the internal wire terminations from tension and flexing. Whether you are powering conveyor systems, large motors, or temporary power distribution units, the Hubbell HBL21414B delivers the reliability professionals demand.

Key Industrial Benefits

FAQ

This is a Hubbellock® device, which uses a specific locking configuration designed for higher safety and retention than standard NEMA locking devices. It is not interchangeable with NEMA configurations.

No, the HBL21414B is a 4-wire device (3 poles + ground) and has a unique twist-lock configuration. It will only mate with a corresponding Hubbellock male plug.

It typically accepts wire sizes ranging from #10 AWG to #6 AWG, but you should check the specific instruction sheet included with the product for the exact range.

Yes, provided the machine draws less than 30 Amps and utilizes a 3-phase or compatible wiring setup. However, it is rated up to 600V, so it is often used for higher voltage equipment.

The HBL21414B typically features a heavy-duty nylon (plastic) housing that is impact and chemical resistant. Some older or specific variations of Hubbellock are armored, but the 'B' suffix usually denotes the black nylon body.

Yes, it is a 4-wire grounding device, meaning it carries three hot lines (or two hots and a neutral depending on use) and one dedicated ground wire.

The connector uses box terminals with pressure screws. You strip the wire insulation, insert the copper strands into the terminal box, and tighten the screw to clamp it down securely.

This is the 'Connector Body', which is the female end that goes on the end of an extension cord. It mates with a 'Plug' (male) or an 'Inlet'.
