Newmar PX-2 Junction Box Waterproof
Newmar PX-2 Junction Box Waterproof — Product description
Why Choose the Newmar PX-2 for Your Marine Wiring Needs?
When you're out on the water, reliable electrical connections are non-negotiable. The Newmar PX-2 waterproof junction box steps up as a go-to solution for boat owners and marine professionals tackling wiring setups above or below decks. Built to shrug off occasional spray and harsh marine conditions, this box uses tough, non-corrosive high-impact polypropylene that won't rust or degrade like metal alternatives. Its snap-on cover locks in a watertight seal, giving you peace of mind during those unexpected splashes or downpours.
What sets the PX-2 apart is its "universal" cut-to-fit cable entries. These graduated ports handle a broad range of cable diameters—from slim signal wires to chunkier power lines—without needing extra fittings. Inside, you'll find two pre-installed connector strips, each with six positions and captive screw terminals that meet ABYC standards for secure, vibration-resistant connections. Plus, multiple knockouts make adding conduit a breeze if your setup calls for it.
With an IEC IP54 rating, it withstands water jets from any angle without letting moisture sneak in—perfect for bilges, cockpits, or exposed helm stations. Whether you're retrofitting an older vessel or wiring a new build, the PX-2 keeps circuits protected and organized.
Key Advantages in Real-World Marine Applications
- Durable Material Choice: Polypropylene resists corrosion from saltwater, UV exposure, and impacts better than traditional plastic or metal boxes, extending service life in salty environments.
- Flexible Installation: Seven cable entry ports come fully installed, ready for immediate use, while knockouts allow seamless integration with rigid conduit systems common in larger yachts.
- ABYC Compliance: Captive screws prevent loosening from boat vibrations, ensuring terminals stay tight—critical for safety and reliability on rough seas.
- Space-Saver Design: Compact footprint (3.35 x 3.35 x 1.66 inches) fits tight spaces without sacrificing capacity for up to 12 wire terminations (two 6-position strips).
- Versatile for DIY or Pro: No special tools needed for basic installs; just cut entries to size, snap on the cover, and secure with screws.

Pro Tips for Installing Your PX-2 Junction Box
- Plan Your Layout: Map out wire runs to maximize the seven entry ports; use the graduated slots for varying cable sizes.
- Prep the Entries: Score and trim ports with a sharp knife for a snug fit—too loose risks leaks, too tight damages insulation.
- Secure Connections: Strip wires to the recommended length, twist strands firmly, and tighten captive screws to spec for optimal crimp without over-torquing.
- Mount Smartly: Use stainless screws into a backing plate; position away from constant flooding but accessible for inspections.
- Test Thoroughly: After sealing, spray-test with a hose to verify IP54 integrity before finalizing.
These steps ensure a bulletproof setup that lasts seasons, minimizing downtime and costly rewiring.
