FAQs
The WP39 accepts conductors in the #20 through #8 range, enabling it to handle a wide variety of common building and control wiring. This compatibility supports straightforward terminations in outdoor or damp locations and aligns with standard AWG sizing used in electrical installations.
Yes. The connector is rated for up to 600 V and a maximum operating temperature of 105 °C (221 °F). These specifications provide a robust safety margin for industrial and outdoor applications, reducing the risk of insulation breakdown and ensuring reliable performance in demanding conditions.
The Marrette WP39 jar contains 100 units, simplifying on-site re-termination tasks and reducing handling time. For larger projects, outer packaging details indicate 1,000 units per container, supporting bulk procurement and inventory management for electrical contractors and distributors.
The WP39 is cULus listed, indicating compliance with North American electrical safety standards. This certification helps ensure code conformance for installations in commercial and industrial settings and supports smoother inspections and approvals on job sites.
Ensure conductors are within the #20–#8 range and insert fully before twisting on. Verify the connector is clean and free of debris to maintain the seal, and use the blue/red code for visual confirmation of correct pairing. Refer to Data Sheet TDS000899 for additional installation guidance and compliance considerations.
