Eaton NCGS521 Solar Cord Grip - IP68, Nylon, 1-1/2"
Part Number: NCGS521
Quick Summary
NCGS521 solar cord grip secures solar cable entries in outdoor electrical enclosures. For engineers wrestling with weatherproofing, strain relief, and reliable IP protection in harsh environments, installation can be time consuming without a proven solution. IP68 ingress protection, NEC/CEC compliance, and suitability for ordinary/non-hazardous locations ensure robust field performance. This nylon, 1-1/2" trade-size cord grip reduces maintenance and downtime by providing durable sealing for USE-2 cables (#12/#10 AWG), while simplifying installation in dense solar arrays. Its non-metallic body aids electrical insulation and reduces galvanic corrosion when paired with aluminum components. By standardizing on NCGS521, procurement teams gain consistency across projects and improve compliance tracking.

FAQs
Install the NCGS521 by selecting the 1-1/2" trade-size grip, routing USE-2 cables (#12 or #10 AWG) through the 21-hole pattern, and securing with appropriate gland hardware. Ensure cable entries are clean and the seal is seated completely to maintain IP68 protection. Use compatible connectors and verify NEC/CEC compliance before commissioning.
IP68 ensures robust protection against water ingress and dust ingress in harsh outdoor conditions, which is critical for solar enclosures exposed to rain, wash-downs, and desert dust. This rating translates to lower maintenance costs and fewer moisture-related faults over the system’s lifetime.
Yes. The NCGS521 is designed for 1-1/2" trade-size applications and supports multiple wires through its 21-hole array. Its nylon body provides insulation and resistance to environmental stress, making it compatible with standard conduit and gland fittings used in solar installations.
NCGS521 is NEC/CEC compliant and rated for Ordinary/Non-Hazardous Locations. Its UL-related certifications can be referenced via the provided UL certification pages, and it is designed to meet typical solar field safety and performance requirements.
The nylon construction and IP68 sealing reduce maintenance visits and extend component life in outdoor environments. The 21-hole pattern allows consolidated cable management, lowering assembly time, while NEC/CEC compliance minimizes regulatory risk, leading to faster project approvals and lower total cost of ownership.
