Pro-Trade PT-WC3 Black/Gray wire connectors provide a weatherproof, UL-listed solution for irrigation and low-voltage outdoor lighting systems. Designed for installers and homeowners who need reliable sealed connections in wet, damp, or buried applications when used according to ratings.

  • UL-listed sealed connector: Listed for use as a sealed wire connector to protect connections in wet, damp, and dry locations when installed in an enclosure.
  • Voltage rating: Rated for 600V maximum on building wire and 1000V maximum for signs or luminaires, giving broad compatibility for lighting and low-voltage systems.
  • Wire range: Accepts common low-voltage gauge sizes (product labeled for #22–#8), making it suitable for typical irrigation and landscape lighting runs.
  • Direct-bury guidance: Can be used for direct-bury applications when operating at 30 volts or less; when used underground, follow local code and enclosure requirements.
  • Durable, weather-resistant design: Black/gray waterproof housing and sealed cap help maintain secure, corrosion-resistant connections outdoors.
  • Pack options for any job: Available in 20-piece bag and 100-piece canister SKUs (PT-WC3-BKGY-20 and PT-WC3-BKGY-100) for installers or smaller projects.

Each connector is engineered to simplify outdoor wiring: push wires in, twist/seat the seal, and place the assembly in an appropriate enclosure or buried-rated junction box when required. For long-term performance, use within the stated voltage limits, verify compatibility with conductor insulation types, and follow local electrical and irrigation codes during installation.
