FAQs
The CGB393 supports a cable range of 0.250 to 0.375 inches in diameter, specifically for non-armoured tray cables. When selecting this gland, measure the outer insulation diameter to ensure it fits within the specified range. This helps ensure proper sealing, strain relief, and enclosure integrity while minimizing the need for multiple gland sizes in a single project.
Yes, the CGB393 is rated for ordinary/non-hazardous locations with a NEMA 3R protection level, which provides rain and ice exposure resistance. While it supports outdoor use in appropriate environments, avoid hazardous locations and ensure the installation complies with NEC/CEC and UL requirements for your facility.
The gland uses a standard 1" NPT thread, enabling easy compatibility with common conduit and enclosure fittings. This standardization reduces installation time, allows reuse of existing hardware, and simplifies retrofits in steel enclosures or control panels, provided the enclosure has compatible NPT ports and the cable diameter falls within the 0.250-0.375 in range.
CGB393 aligns with NEC/CEC standards and carries a NEMA 3R rating, suitable for ordinary locations. UL certification coverage further supports compliance during audits and qualify procurement. This mix of certifications helps streamline purchasing, reduces audit findings, and ensures consistent performance across plant wiring practices.
Follow standard installation guidelines for Crouse-Hinds CG fittings, including IF 513A CG Fittings Installation instructions. Ensure the cable diameter is within 0.250-0.375 in, use the correct 1" NPT gland, and secure the gland to a compatible steel enclosure. Proper torque and sealing practices maximize ingress protection and long-term reliability.
