FAQs
The NPL300500 is ideal for joining rigid/IMC conduit runs in non-hazardous areas, including control panels, machine enclosures, and service entrances. Its galvanized steel construction withstands damp environments, helping maintain reliable electrical connections without frequent replacement or maintenance.
Galvanized coating provides a durable barrier against moisture, chemicals, and atmospheric exposure. This translates to longer service life in harsh industrial settings, reduced coating degradation, and lower lifecycle maintenance costs compared with uncoated fittings.
NPL300500 aligns with NEC/CEC standards and offers UL-listed certification options. This ensures regulatory compliance for safe, certified installations across North American facilities, accelerating approvals and reducing audit risk for projects.
NPL300500 is designed for rigid/IMC conduit systems, ensuring straightforward compatibility with standard fittings and housings. When installing, verify thread engagement and use compatible locknuts, washers, and plugs to maintain electrical continuity and enclosure integrity in automation environments.
Using the NPL300500 reduces maintenance frequency due to its corrosion resistance and robust galvanization. The standardized size and compatibility with common conduit systems streamline procurement and installation, shortening project timelines and lowering total installed cost (TIC) over the equipment’s lifecycle.
