Truck-Lite says it developed the Super 50 Junction Box for today’s trailers that operate in chemically harsh environments that are intensified by the increased aggressiveness of snow-fighting compounds. Trailers also are made with increased electrical complexity, with more interior lighting, power liftgates, warning systems and added sensors; these conditions require greater capacity and more protection for electrical systems.

To fight corrosion, the Super 50 Junction Box is made from chemically and electrically inert impact-resistant ABS plastic. A clear lid is designed to allows easy inspection of wiring inside the box, while the assembly is sealed from corrosive agents with a silicone gasket. The box, which has 16 terminal studs with four common grounds, is fed by up to 12 cables entering through any of 12 pretapped ports that accept either filler plugs or compression fittings. The capacity of the Super 50 Junction Box is for 50 percent more circuits than ordinary boxes provide, according to the company. Four mounting holes on the base (but outside the sealed interior) are eyelet-reinforced to facilitate increased durability and to maintain the integrity of the box.
