Bryant 4779NC – Frequently Asked Questions

1) What motor amp ratings does the Bryant 4779NC connector come in?
Three Motor Full Load Amp ratings are offered on the 5C7W A connector: 15A as part number 4779NC, 30A as 530C7W, and 100A as 4100C9W. Pick the one that matches the nameplate FLA of the motor or equipment you are hooking up, not the breaker size.
2) Can I use the Bryant 4779NC on a 480V three-phase motor circuit?
Yes. The connector is rated 277/480V, which covers 277V line-to-neutral and 480V line-to-line work typical of commercial and industrial motor and power distribution circuits.
3) Will this Bryant connector mate with a standard NEMA 5-20 plug?
No. This is a 5C7W A configuration device, a motor-rated pin-and-sleeve style interlocking configuration, and it will only mate with a correspondingly configured 5C7W A device. A 125V NEMA 5-20 straight blade plug is a different pattern entirely; for that you want a straight blade connector such as the Leviton 8319-C NEMA 5-20R.
4) Is there a watertight alternative to the Bryant 4779NC connector for outdoor or washdown equipment?
The Pass & Seymour Turnlok 27W series connector is a 20A watertight device rated NEMA 4X/6P, which is the enclosure rating to look for in wet, outdoor, or washdown locations. The Bryant 4779NC is a 277/480V 5C7W A configuration connector offered across Motor FLA ratings of 15A, 30A, and 100A; pick it when the 277/480V motor circuit and 5C7W A mating configuration are what governs, and the Turnlok 27W when a sealed 20A connection is the requirement.
5) What connector should I use for a 125V 20A straight blade cord run instead of the Bryant 4779NC?
The Bryant 4779NC is a 277/480V connector in the 5C7W A configuration, so it is not the part for a 125V straight blade cord set. For that, the Leviton industrial grade straight blade connector 15W33 is a 3-wire 2-pole device rated 125V 20A. Use the Bryant 4779NC where the circuit is a 277/480V motor or equipment feed and the mating device is configured 5C7W A.
6) What is the difference between a motor-rated connector like the Bryant 4779NC and a general purpose industrial connector?
A motor-rated device is selected by the motor's Full Load Amps rather than by a simple receptacle amp rating, which is why the 4779NC is offered in 15A, 30A and 100A FLA versions on a 277/480V circuit. A general purpose industrial straight blade connector, like the Leviton 3-wire 2-pole 125V 20A industrial grade unit, is sized by circuit amperage on low voltage branch wiring and is not intended for 480V motor loads.
7) Do I need a matching plug or inlet to complete the connection with the Bryant 4779NC?
Yes, the connector is only half the pair. It is a female connector body, so you need a correspondingly configured 5C7W A mating device to land the cord or equipment end. Ordering the connector alone leaves the circuit unfinished.
8) If I am standardizing equipment hookups across a plant, can I use the same Bryant configuration for different size motors?
Yes, within limits. All three versions share the 5C7W A configuration, so the mating pattern stays consistent across the plant while the FLA rating changes with the load, 15A, 30A or 100A. Keep the FLA version matched to each motor's nameplate rather than using one size everywhere.
9) Can a hospital grade 5-20R connector be used in place of the Bryant 4779NC in a healthcare facility?
No. The Leviton 8319-C is a hospital grade NEMA 5-20R connector supplied in packs of 100, which is a 125V 20A receptacle-style connector for patient care area cord sets. The Bryant 4779NC is a 277/480V connector in the 5C7W A configuration sold in Motor FLA ratings from 15A to 100A, intended for motor and equipment circuits. The two serve different circuits and do not interchange, even in the same building.
10) Is the Bryant 4779NC suitable for a hospital or healthcare facility circuit?
There is no hospital grade designation on the Bryant 5C7W A connector; it is specified for commercial and industrial power distribution and motor circuits at 277/480V. Where a hospital grade device is called for on 125V patient-care branch circuits, the Leviton 8319-C is a hospital grade NEMA 5-20R connector.
11) What is the difference between the Bryant 4779NC and a Leviton ML2 midget connector?
The Leviton ML2-C is a midget connector from the ML2 series, sold in packs of 100 for small-gauge electrical wiring connections. The Bryant 4779NC is a 277/480V power connector built to the 5C7W A configuration and offered in Motor FLA ratings of 15A, 30A, and 100A for commercial and industrial motor and equipment circuits. The ML2 is a small-device connector; the 4779NC is sized and rated for higher-voltage distribution work.
