| Designed for high-load power delivery, this 50 Amp, 125/250V heavy-duty receptacle box features a NEMA 10-50R configuration built with high-conductivity copper alloy contact terminals. The internal terminal layout utilizes heavy-duty screw clamps engineered to accommodate high-gauge conductors (Hot A, Hot B, and Ground/Neutral configurations), minimizing contact resistance and heat buildup during continuous peak-load operation. | |||||||||
Designed for high-load power delivery, this 50 Amp, 125/250V heavy-duty receptacle box features a NEMA 10-50R configuration built with high-conductivity copper alloy contact terminals. The internal terminal layout utilizes heavy-duty screw clamps engineered to accommodate high-gauge conductors (Hot A, Hot B, and Ground/Neutral configurations), minimizing contact resistance and heat buildup during continuous peak-load operation.
The physical enclosure is constructed from high-impact, UV-stabilized thermoplastic housing designed to withstand mechanical impacts, outdoor weathering, and thermal stress. Measuring 100mm x 100mm x 91mm, the compact enclosure integrates a spring-loaded transparent protective cover with a rubber gasket seal, securing an IP66 ingress protection rating against rain, snow, dust, and corrosive airborne particulates.
Multi-Size Conduit Knockouts: Features pre-configured threaded entry ports, including an NPT 1" top port, NPT 3/4" dual side ports, and a rear knock-out option (20-33mm) for flexible conduit routing.
Surface & Flush Mounting Compatibility: Integrated with 4 corner mounting screw holes (74mm x 45mm spacing) for secure attachment to wall studs, pedestal poles, or equipment enclosures.
Enclosed Accessories: Includes heavy-duty mounting screws, wall anchors, and protective screw cover caps to seal mounting points against moisture ingress.
High-Power Outdoor Connections: Ideal for recreational vehicles, electric arc welders, high-capacity portable generators, and outdoor power distribution pedestals.
Environmental Sealing: The flip lid buckle mechanism creates a tight seal around the socket interface when closed, ensuring long-term operational safety in demanding outdoor environments.
The heavy-duty internal terminal blocks are engineered to accept thick copper conductors typically rated for 50-amp loads, supporting up to 6 AWG wire sizes. The screw clamp connections ensure a high-torque mechanical grip to prevent terminal loosening under thermal cycling.
The housing utilizes a continuous perimeter rubber sealing gasket between the main enclosure body and the front bezel. Additionally, the spring-loaded clear front cover features an active latching buckle mechanism that keeps the receptacle completely sealed from heavy rain, splashing water, windblown dust, and debris when not in active use.
The enclosure offers multiple knockouts and threaded entry points, including a top NPT 1" entry, dual side NPT 3/4" threaded ports, and a rear cut-out range of 20mm to 33mm. This multi-directional entry layout allows seamless integration with standard flexible or rigid electrical conduits.

Q1: What makes this ABS enclosure suitable for direct burial or underground applications compared to standard PVC?
A1: High-grade ABS provides significantly higher impact resistance, tensile strength, and structural rigidity than standard PVC. This allows the enclosure to withstand the constant soil pressure, gravel shifting, and freeze-thaw cycles common in underground environments without cracking or deforming, while naturally resisting underground moisture, fungi, and soil chemicals.
Q2: How does the cable sealing system maintain its IP68 rating under high hydrostatic pressure?
A2: The enclosure utilizes a combination of compression-fit silicone gaskets along the lid and specialized mechanical cable glands at the entry points. When the glands are tightened, they compress a internal rubber seal uniformly around the cable jacket, preventing water tracking even when the unit is submerged or subjected to rising groundwater levels.
Q3: Can these plastic enclosures safely operate in industrial areas requiring explosion-proof specifications?
A3: Yes. The enclosure is engineered with high-density, flame-retardant ABS material that mitigates the risk of static build-up and surface arc ignition. Its robust wall thickness and secure fastening mechanism are designed to prevent external gases or dust from contacting internal electrical sparks, making it ideal for zone-classified dust or non-mining volatile environments.
Q4: Are these boxes resistant to prolonged sunlight if used above ground before transitioning underground?
A4: While standard ABS can degrade under prolonged UV exposure, our industrial-grade enclosures are manufactured with integrated UV-stabilizing compounds. This advanced formulation prevents the plastic from becoming brittle, fading, or cracking when exposed to direct sunlight in outdoor, above-ground installations.
Q1. Can I request samples of waterproof aluminum enclosures before bulk ordering?
A: Absolutely. We encourage sample orders for quality validation and even accept mixed samples. While standard samples are provided free of charge for qualified clients, custom samples may incur a nominal fee that will be credited toward future orders.
