Bryant HBL300MGN 300A Single-Pole Male Power Connector
The Bryant HBL300MGN is a single-pole, 300A rated male connector engineered for high-current electrical connections in industrial and commercial power distribution systems. This male-configured connector is built to handle demanding 300A applications, forming secure, high-amperage connections between power sources and the equipment or panels they feed. The HBL300MGN is available in a choice of color options — Black, Blue, Green, Standard, and White — letting electricians color-code circuits for fast identification across multi-circuit power setups. Its single-conductor-per-connector design supports flexible, modular power runs for facilities, contractors, and event or production crews that need dependable high-amperage hookups without relying on multi-conductor cable assemblies.
Key Features
- Amperage Rating: Rated for 300A, suited for high-current electrical circuits and heavy-duty power distribution runs.
- Single-Pole Configuration: One conductor per connector for modular, flexible power hookups and simplified circuit routing compared to fixed multi-pole cable assemblies.
- Male Connector End: Designed to mate with a corresponding female single-pole connector for a secure, polarized, high-amperage electrical connection.
- Model HBL300MGN: Cataloged under the Bryant HBL300MGN designation for straightforward cross-referencing, ordering, and replacement in the field.
- Color Options: Offered in Black, Blue, Green, Standard, and White to support color-coded phase and circuit identification on multi-connector power setups.
- Heavy-Duty Application Use: Suited for facilities and equipment requiring 300A single-pole connections rather than standard branch-circuit devices, where high current loads must be moved safely between sources and loads.
- Modular Power Distribution: Pairs with matching female connectors to configure temporary or semi-permanent 300A circuits as job requirements change.

Bryant HBL400MBK – Frequently Asked Questions
1) Is the Bryant HBL300MGN one connector for a complete circuit, or do I need several?
It's a single-pole device, one conductor per connector. So a complete circuit needs one connector per conductor you're running, hot, neutral and ground each get their own. That's what makes single-pole sets useful for modular power runs: you build the circuit you need instead of pulling a fixed multi-conductor assembly.
2) Will the Bryant HBL300MGN male connector mate with a female single-pole connector?
Yes, the male end is made to mate with a corresponding female single-pole connector to form the high-amperage connection. Order the mating female halves in the same quantity as your male ends, one pair per conductor.
3) Can I use a 20A industrial straight blade connector instead of a 300A single-pole connector?
No. Devices like the Leviton 15W33 industrial grade 3-wire 2-pole connector are 125V 20A cord-connector bodies for branch circuits, and the Pass & Seymour Turnlok 27W is a 20A watertight connector. Neither is in the same class as a 300A single-pole feeder connector. If you're moving 300A between a source and a panel or load, you need single-pole devices sized for it, one per conductor.
4) Can a Leviton 15W33 industrial grade connector be used in place of a Bryant HBL300MGN?
No. The Bryant HBL300MGN is a single-pole connector rated 300A with a 1-pole configuration, intended for high-current power distribution feeders. The Leviton 15W33 is an industrial grade straight blade connector, 3-wire 2-pole, rated 125V 20A. Those are different classes of device: the 20A straight blade connector serves cord-and-plug branch circuit loads, while the 300A single-pole handles feeder-level current one conductor at a time. They do not intermate and one cannot carry the other's load.
5) For a patient care area receptacle circuit, what should I use instead of the Bryant HBL300MGN single-pole connector?
The HBL300MGN is a 300A single-pole power connector for feeder and power distribution work, not a device for 20A healthcare branch circuits. For that application the Leviton 8319-C is a hospital grade NEMA 5-20R connector in black, supplied in a pack of 100. The hospital grade listing and the 5-20R configuration are what a patient care cord connection calls for; the Bryant part is a high-amperage single-conductor connector and has no NEMA straight blade configuration.
6) What current is the Bryant single-pole male connector rated for?
300A. That puts it in feeder and distribution territory, generator-to-panel ties, portable power hookups, and heavy equipment feeds, rather than anything you'd use on a standard branch circuit.
7) What colors does the Bryant 300A single-pole male connector come in, and does the color matter electrically?
Five choices: Black, Blue, Green, Standard, and White. The color is for identification only, it doesn't change the rating or the mating configuration. Crews use it to color-code phases, neutral and ground so a multi-connector setup can be read at a glance and reconnected correctly.
8) I need a hospital grade receptacle connector, not a high-amp single-pole. What should I look at?
A 300A single-pole male connector is the wrong device for that. For a hospital grade cord connector, the Leviton 8319-C is a hospital grade NEMA 5-20R connector in black, supplied in a pack of 100. Single-pole 300A devices are feeder hardware and carry no hospital grade designation.
9) I need a watertight connector for outdoor temporary power. Is the Bryant HBL300MGN the right choice, or is there a sealed option?
The Bryant HBL300MGN is a 300A single-pole male connector used for generator, panel, and portable power interconnections, and its published data covers amperage and 1-pole configuration rather than an enclosure rating. Where a sealed 20A device is what the circuit needs, the Pass and Seymour Turnlok 27W Series connector is rated NEMA 4X/6P watertight and comes in yellow. The two are not alternatives for the same circuit: the 27W Series is a 20A Turnlok device, while the Bryant handles 300A on a single conductor.
10) Is a Leviton ML2 midget connector a smaller version of the Bryant HBL300MGN?
No. The Leviton ML2-C is a midget connector for electrical wiring in the ML2 series, sold in packs of 100 for small-gauge wiring device work. The Bryant HBL300MGN is a 300A single-pole male connector that mates with a corresponding female single-pole connector for high-amperage power runs. Despite both being called connectors, they are unrelated device families with no shared mating interface, so the ML2 cannot serve as a compact stand-in on a 300A feeder.
11) When do I order the Bryant HBL300MGN rather than a standard 20A cord connector?
Order the Bryant HBL300MGN when the circuit is a 300A single-conductor power run, such as industrial power distribution, generator-to-panel interconnection, or event and production power, where each phase or conductor terminates in its own connector and color coding identifies the circuit. A standard cord connector such as the Leviton 15W33, a 3-wire 2-pole 125V 20A industrial grade straight blade connector, or the Pass and Seymour Turnlok 27W Series 20A watertight connector, belongs on branch circuit equipment cords instead. The dividing line is current: 20A device wiring versus 300A feeder-level single-pole connections.
12) Is a Bryant single-pole 300A connector suitable for temporary event and production power?
Yes, that's one of its intended uses along with industrial distribution, generator and panel interconnections, and portable power hookups. Because each conductor terminates in its own connector, you can reconfigure a 300A run as the load plan changes instead of being locked into a fixed cable assembly.
