North America Plugs – NEMA 5-15P & NEMA 1-15P

Certified Power Plug Harness Solutions from Celestix

Celestix manufactures precision-engineered North America plug harnesses that meet and exceed NEMA 1-15P and NEMA 5-15P standards. Our assemblies include compact and heavy-duty plug formats, right-angled connector variants, and full integration with high-performance wiring harness and cable assembly systems. Designed to ensure safe, repeatable operation, each harness is custom-built, compliance-ready, and validated to perform in the most demanding real-world environments.

Built in-house. Tested beyond spec. Delivered with traceable confidence.

NEMA Standards – Grounded in Performance and Safety

The National Electrical Manufacturers Association (NEMA) defines the standards for plugs and sockets used in the United States, Canada, and several other international markets. Celestix manufactures to these exacting standards, ensuring:

• NEMA 1-15P – 2-prong, ungrounded; rated 125V, 15A

• NEMA 5-15P – 3-prong, grounded; rated 125V, 15A

• Voltage/Frequency – 125V AC, 60Hz

• Certifications – UL, CSA, RoHS, CE, REACH

Our North America power harnesses and NEMA plug cables are built to last with low contact resistance, thermal resilience, and mechanical robustness. These solutions reduce downstream rework, eliminate mismating risks, and are fully compatible with OEM global compliance protocols. Our designs are DFMA-optimized, routed for stress relief, and leverage error-proofed connectors with keyed entries and secure locking to prevent mismating during installation.

Celestix supports NEMA 5-15P small harness, NEMA 5-15P big harness, and NEMA 5-15P right angled cable configurations, each built with materials and terminations chosen for load stability, ingress resistance, and mating integrity. Our durable NEMA plug harness solutions are pre-tested for fault resistance and grounding continuity.

Configured for Integration – Designed for Deployment

Every plug harness system can be tailored to support:

• Inline components: LED indicators, fuses, and on/off switches

• Custom overmolds with logo, color coding, or polarized locking

• Jacket materials matched to heat class, flex radius, or UL rating

• Multi-drop or single-ended connections

• Full bundling with modular cable and harness assembly systems

Celestix offers flexible NEMA plug cables, rugged American plug harness configurations, and smart North America plug options with integrated diagnostics or visual indicators. Whether your design requires a compact North America harness for embedded installs or a shielded NEMA plug wiring configuration for EMI-sensitive use cases, we have you covered.

Compliance and Quality You Can Validate

• UL-approved NEMA plugs and CSA-compliant North America harnesses

• RoHS American plug wiring and CE/REACH declarations

• ISO 9001 / IATF 16949 manufacturing for tiered supply chains

• Test documentation includes:

• Continuity

• Dielectric withstand

• Pull test data

• Material CoC and lot traceability

All assemblies qualify as NEMA-standard plug harnesses and undergo process-driven validation to Class 3 IPC/WHMA-A-620.

Supporting Your Entire Program Lifecycle

From prototype North America plug cable development to full-scale contract American plug harness manufacturing, Celestix supports:

• OEM drawings for OEM NEMA 5-15P plug harness builds
