Additional 277 Volt Plug Types Information
Common in the lighting industry, our USA manufactured 277 Volt Power Cords are available in a variety of wire types, sizes, colors, and lengths. Kord King will manufacture opposite ends to our customer’s specifications, such as wire end termination, jacket stripping or adding contacts and housings. Kord King’s 277 Volt Power Cords ergonomic plug design also allows for easy handling. All components for our 277 Volt Power Cords sets are RoHS compliant, UL and CSA listed and approved.
We also manufacture the 277 Volt plug in Twist Lock configurations, for added versatility.
277 Volt Plug Configurations
277 volt cords are offered in two primary plug types:
- NEMA 7 15P straight blade plug
- NEMA 7 15R twist lock receptacle configuration
These options support equipment that requires either a standard insertion method or a locking interface to prevent accidental disconnection. Both plug styles are molded for durability and designed to maintain consistent electrical contact under load.
Mechanical Design and Handling Features
The molded plug body includes an ergonomic profile that supports secure handling during installation and removal. Deep ridges and reinforced strain relief structures help maintain conductor integrity during repeated use. These features are especially useful in lighting installations where cords may be accessed frequently during maintenance or fixture replacement.
All components are UL listed, CSA approved, and RoHS compliant, supporting use in regulated environments and ensuring compatibility with industry standards.
Application Areas
277 volt power cords are used in:
- Commercial lighting systems
- Industrial lighting fixtures
- High bay and low bay luminaires
- Ballast driven lighting equipment
- LED drivers and retrofit assemblies
- Facilities with 277 volt distribution panels
These cords support equipment that relies on higher voltage circuits for improved efficiency and reduced current draw.
Configuration Options for OEM Integration
Engineers can specify:
- Wire gauge based on amperage requirements
- Straight blade or twist lock plug patterns
- Cord length and jacket color
- Opposite end termination style
- Identification or labeling requirements
- Jacket stripping or contact installation
These options allow the cord to be tailored to fixture design, installation method, and maintenance workflow.
FAQ
Why Are 277 Volt Power Cords Common in Lighting Applications?
Many commercial and industrial facilities use 277 volt single phase circuits for lighting because the higher voltage reduces current draw and improves distribution efficiency.
What Is the Difference Between a Straight Blade and Twist Lock 277 Volt Plug?
A straight blade NEMA 7 15P plug inserts normally into the receptacle, while a twist lock version rotates into place to prevent accidental disconnection in environments with vibration or movement.
Which Wire Gauges Are Available for 277 Volt Cords?
Wire options include 18/3, 16/3, 14/3 & 12/3 selected based on the amperage requirements of the connected lighting equipment.
Can Opposite End Terminations Be Customized for Specific Fixtures?
Yes. Options include stripped leads, jacket removal, added contacts, housings, or connectorized ends depending on the fixture’s wiring method.
