Product Details

The NewMar PX-3 is a waterproof junction box designed for marine electrical installations above or below decks, even in areas exposed to occasional spray. Constructed from rugged, non-corrosive, high-impact polypropylene, this junction box provides reliable protection for wiring connections in harsh marine environments.

Pre-Installed Connector Strips:

The PX-3 includes two 9-position connector strips with screw compression wire terminals that secure wires without requiring lugs. These molded nylon connectors feature brass barrels that capture wires, held in place by a stainless steel "finger" compressed by a screw. This design protects copper strands from cuts and breakage while meeting ABYC standards, as the screw never makes direct contact with the wire.

Key Features:

  • High-impact polypropylene construction resists corrosion and withstands marine conditions
  • Snap-on cover creates a watertight seal for reliable protection
  • Seven universal cut-to-fit graduated cable entries accommodate wire diameters from 0.14" to 0.99" (3.5mm to 25.5mm)
  • Two 9-position connector strips accept wire up to 16 AWG
  • Multiple knockout ports provided for optional conduit access
  • IP55 waterproof rating protects against water jets from any direction

Specifications:

  • Connector Strips: 2 strips, 9 positions each
  • Maximum Wire Gauge: 16 AWG
  • Cable Entries: 7 ports (all installed)
  • Cable Diameter Range: 0.14" - 0.99" (3.5mm - 25.5mm)
  • Box Dimensions: 4.45" L x 4.45" W x 2.29" H (11.3cm x 11.3cm x 5.8cm)

Ideal for electronic installations on boats, RVs, and other marine applications where reliable, waterproof electrical connections are essential.
