Junction box is an important part of household and building electrical wiring system. These boxes are usually made of metal or plastic. The purpose is to place and secure the electrical connections of the structure. The wire pipe is connected with the junction box, and the wires in the wire pipe are connected in the junction box to protect and connect the wires.

Why is it so important to choose the right junction box ?
The junction box protects the parts , safeguard these components from the hot sun, cold winds and precipitation, and prolongs the service life of the parts.

What's the features of the right junction box requires ?
The enclosure has strong anti-aging and ultraviolet resistance. UV rays and high temperatures can cause device components to overheat, melt or otherwise deform. So when we choose an outdoor junction box, The terminal box with anti ultraviolet function has a longer service life outdoors.

Meet the use requirements of under outdoor harsh environmental conditions. Water and condensation inside the enclosure can cause device malfunctions and damage components. Therefore, the Junction box with waterproof function is particularly important. Apart from waterproof sealing design. An essential safety feature of anti electric shock insulation performance, is also an important features.

So we need to choose the right the material and IP rating for the electrical enclosures.

The most common plastic enclosure material is ABS plastic, polycarbonate plastic,

What is the difference between ABS and PC?

ABS is the acronym of acrylonitrile butadiene styrene. It is a thermoplastic polymer material with high strength, good toughness and easy processing. ABS resin is a graft copolymer of acrylonitrile, 1,3-butadiene and styrene. Among them, acrylonitrile accounts for 15% ~ 35%, butadiene accounts for 5% ~ 30% and styrene accounts for 40% ~ 60%. ABS resin is a yellowish solid with certain toughness, and the density is about 1.04 ~ 1.06g/cm3.
Polycarbonate,    shorter form is PC. Its high impact strength, good dimensional stability, colorless and transparent, good coloring, good electrical insulation, corrosion resistance and wear resistance.

Metal enclosures made from materials like stainless steel and aluminum are also an excellent choice for outdoor junction boxes
Aluminum alloy has low density but high strength. It is close to or higher than high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent conductivity, thermal conductivity and corrosion resistance. It is widely used in industry.
Stainless steel is mainly nickel chromium alloy, corrosion resistant, heat resistance, oxidation resistance and good weldability.

It’s also important to choose an outdoor rated NEMA enclosure or IP rated enclosure to protect your device. These rating systems provide a quick and clear way to understand how much protection an enclosure offers against environmental hazards like water and dust.

NEMA standards are used mainly in North America. Outdoor enclosures should have an outdoor NEMA rating like NEMA 4X or NEMA 6P. For more information about what these ratings mean, see our NEMA ratings guide.

NEMA Ratings Chart

IP standards are used worldwide, but especially in the European Union. An outdoor enclosure should feature a waterproof and dustproof IP rating, such as an IP66 or IP68. Our IP ratings guide offers more information on the IP ratings system.

IP-65, IP-67, IP69K? 4 Things You Should Know.
