FAQs
Begin by verifying the enclosure opening is suitable for a 2" cord grip. Route USE-2 conductors (#10 or #12 AWG) through the 31-hole array, ensuring each conductor fits within the 5 mm hole diameter. Seal the entry per IP68 requirements and consult Eaton's specification sheet for torque and gland details to prevent leaks and ensure reliable performance in outdoor PV environments.
IP68 rating indicates complete dust ingress protection and protection against prolonged immersion in water. The nylon body and gasket design deliver an enduring seal, even under temperature cycling and wet conditions typical of solar installations, which reduces moisture-related terminations and maintenance needs.
Yes. The NCGS631 is classified for Ordinary/Non-Hazardous Locations and meets NEC/CEC standards, making it appropriate for common solar deployments on commercial and industrial sites without special corrosion or explosion protection requirements.
The product carries NEC/CEC standards compliance for electrical installations and is designed to support compliant wiring practices in ordinary outdoor environments. This alignment simplifies customer audits, commissioning, and ongoing regulatory adherence for PV systems.
The nylon construction, IP68 sealing, and compatibility with standard USE-2 conductors deliver long service life with fewer field adjustments. This reduces maintenance intervals, lowers labor costs during installation, and improves overall system reliability for solar farms and rooftop PV deployments.
