Hubbell 60CM83A FD Box 3/4 NPT

Engineered for the relentless demands of marine environments, the Hubbell FD Box with dual 3/4" NPT hubs stands as a rugged guardian for your electrical connections. Crafted from high-impact PBT material and paired with a stainless steel mounting plate, this enclosure delivers unmatched corrosion resistance and durability against saltwater spray, UV exposure, and constant vibration. Whether you're wiring up deck lighting on a fishing vessel or securing power feeds in a dockside setup, this box ensures reliable performance without the pitfalls of rust or failure.

Superior Build for Harsh Conditions

Unlike standard junction boxes that falter in wet, salty air, this Hubbell marine-grade solution uses polybutylene terephthalate (PBT)—a thermoplastic that's naturally non-conductive, flame-retardant, and tough enough to shrug off impacts from docking mishaps or rough seas. The stainless steel mounting plate provides a secure, rust-proof base for flush deck installations, blending seamlessly into boat decks or pier surfaces while keeping connections watertight.

• Dual 3/4" NPT Hubs: Perfect for routing cables or conduits, offering flexibility for straight-through or angled entries without compromising seal integrity.
• Flush Deck Design: Low-profile to minimize trip hazards and maintain a clean aesthetic on vessels or waterfront structures.
• Corrosion-Proof Construction: Battles ozone, chemicals, and humidity, extending service life in coastal climates.
• Easy Accessibility: Threaded hubs and secure covers allow quick inspections and maintenance without tools in most cases.

Detailed Specifications

Real-World Applications and Benefits

Boat owners and marine electricians swear by this FD box for its ability to protect critical wiring in navigation systems, bilge pumps, or spotlight circuits. In commercial marinas, it handles feeder lines for shore power pedestals, resisting the daily assault of boat wakes and tidal fluctuations. Key advantages include:

• Longevity: Outlasts aluminum or PVC alternatives in aggressive saltwater settings.
• Safety: Prevents shorts and arcing with its insulated body and IP-rated sealing.
• Versatility: Ideal for both AC and low-voltage DC setups in recreational or workboats.
• Compliance Ready: Meets stringent marine standards for vibration, temperature extremes (-40°F to 176°F), and ingress protection.

Pro Tips for Installation and Maintenance

Position the box in a spot shielded from direct wave splash for optimal performance. Use marine-grade sealants around the NPT hubs and ensure gaskets are seated properly before tightening. For maintenance, periodically check hub threads for debris— a simple wipe-down with freshwater keeps it pristine. Pair it with Hubbell's watertight plugs or cordsets for a bulletproof system that handles years of abuse.
