In outdoor lighting, greenhouse power supply, and stage wiring projects, many wiring waterproof boxes are directly fixed to the wall. The installation steps may seem simple, but the fixation is unstable, and it is prone to loosening and falling off later on, which can also damage the waterproof seal. The “PHLTD Penghan” waterproof junction box made in China comes with reserved fixing holes and can be wall mounted according to specifications for long-term stability and reliability.
Before officially starting construction, it is necessary to select a sturdy and flat wall surface. It is not recommended to install soft hollow wall panels directly. Clean up the floating dust and moss on the wall, mark four fixed points, calibrate with a level, and ensure that the box remains upright after installation. After drilling, clean the dust inside the hole and select matching expansion pipes according to the wall material. Different fixing accessories should be used for concrete, brick walls, and wooden boards. Stainless steel screws should be preferred for outdoor humid environments to prevent rusting and jamming.
When fixing the box, tighten the screws evenly in stages and do not lock a single screw at once to prevent deformation of the shell under stress and damage to the sealing strip of the box cover. A small amount of spacer can be added between the box body and the wall, leaving a small gap to prevent the wall from becoming damp and sticking to the back of the box, reducing the accumulation of condensation. After fixing the box, insert the cables, lock the waterproof cable joints, connect the internal wiring, close the box cover, and check if the seal fits properly.
To maintain long-term stability, several details cannot be ignored. Do not tighten the screws too tightly, as excessive force on the plastic shell can easily cause cracking; In scenarios with high vibration, spring washers can be used to prevent screws from slowly loosening. After installation, gently shake the box for a simple test. Only when there is no shaking can it be considered qualified. Regularly inspect the screws in the later stage to check for rust and looseness, and tighten them in a timely manner.
Many people only care about waterproof performance, but ignore fixed structures. Once the box becomes loose and skewed, there will be gaps in the seal of the box cover, making it easy for rainwater to seep into the interior. Made in China, the “PHLTD Penghan” wiring waterproof box is equipped with standardized wall mounting holes reserved, and the shell has strong deformation resistance. With standardized wall mounting construction, it balances firm installation and reliable waterproofing, making it easy to cope with various outdoor wall wiring scenarios.
