  • How high can the temperature of an outdoor electrical distribution box get

    How high can the temperature of an outdoor electrical distribution box get

    outdoor electrical junction box Under direct sunlight in summer, the surface temperature of the enclosure can easily exceed 60℃. This physical effect of thermal expansion and contraction directly harms the sealing strips. Material Aging: Sealing rings soften and even become sticky at high. An outdoor electrical distribution box serves as the critical junction point where incoming power lines are split into multiple branch circuits for outdoor installations, parking lots, building exteriors, and industrial facilities. In these conditions, it is likely the internal enclosure temperature will be elevated and may exceed safe limits unless the enclosure is equipped with some. In practical terms, this means an outdoor IP65 junction box is dust-tight and can withstand rain, hose spray, or splashes—perfect for outdoor or wet-area use. Why Choose a Waterproof IP65 Junction Box for Outdoor Projects? 1. Key design points include high-quality materials like ABS plastic, aluminum, and stainless steel that resist corrosion and UV.
