FAQs
The NCGS478 is a seven-hole nylon cord grip rated for 1-1/4 inch trade size with an 8 mm hole. To install, align the cable jacket with the grip, tighten the outer nut or clamp according to the catalog page, and verify the 1000V PV cable fits the #8, #10, or #12 AWG range. Ensure IP68 sealing by confirming the gasket seating and cable entry is clean and properly sealed before mounting in a suitable enclosure.
NCGS478 supports 1000V PV cable with wire sizes #8 AWG, #10 AWG, and #12 AWG. The 8 mm hole diameter accommodates the typical PV conductor insulation used in outdoor installations, enabling secure termination and compliance with high-voltage solar wiring standards.
Yes. With IP68 ingress protection and NEC/CEC compliance, the NCGS478 is designed for outdoor solar arrays and enclosures exposed to dust, water, and weather. Its ordinary/non-hazardous area classification further supports safe operation in most commercial and industrial outdoor settings.
NCGS478 aligns with NEC/CEC standards and IP68 protection, ensuring compliance for outdoor, non-hazardous locations. The product page also references UL certification pages for related NCGS components, reinforcing safety and reliability expectations for non-metallic portable cord connectors used in PV installations.
The nylon construction resists corrosion and weathering, reducing maintenance cycles. The seven-hole configuration simplifies, modular terminations, and compatibility with existing NCGS components lowers sparing costs. Overall, expect lower field remediation needs, faster installs, and improved system uptime, contributing to a favorable total cost of ownership in solar projects.
