After the layout of the conduit in the wall and floor is grooved with a non-toothed saw, lay the conduit with a wire diameter not less than 16mm flame-retardant pipe and "86" junction box, then thread the wires through the conduit (when wiring, separate the colors of the phase line and the neutral line, the phase line (L) color should be uniform in the same residence, the neutral line (W) should be blue, and the protective line (PE) should be yellow-green). Secondly, when burying the power conduit, consider maintaining a distance of more than 500mm from weak current pipelines, with a parallel distance of not less than 300mm between the wire conduit and hot water pipes, gas pipes; strong and weak currents are prohibited from being installed in the same conduit to avoid interference with weak current signals. Third, the connection of wires inside the box should use the U-type wrapping method for 6 and a half turns according to national standards to prevent loose connections that could cause "sparking". At the wire joints inside the junction box, "tinning" treatment should be done to prevent oxidation and short circuits, and the conduit should be wrapped with waterproof tape and high-voltage insulation tape. After threading the wires, use insulation tape and waterproof tape to double-insulate the power wire joints. For power lines running along the ceiling, they must pass through conduits, and the wooden keel of the ceiling should be treated for fire and insect prevention to avoid future troubles for the owner. First, when selecting wires, use copper wires and avoid aluminum wires. Because aluminum wires have poor conductivity, they can heat up during electrification and even cause fires. Then, wiring must use insulated conduits. If wires are directly hidden in the wall, it is like having a time bomb at home,隨時(shí)可能漏電, posing a risk. Of course, different types of lines cannot run through the same conduit, such as TV antennas, telephone lines, etc. There should not be too many wire joints; if splicing is necessary, ensure good insulation and moisture protection, and if conditions allow, "tinning" can be done. At the end of the decoration, the owner must request the circuit diagram, which helps prevent circuit system issues and is useful for future upgrades and modifications. Wires buried in the wall must pass through conduits; generally, metal conduits and PVC conduits are options: metal conduits are more expensive but have better anti-interference performance than PVC conduits, are fire-resistant, and provide better protection for wires in the future (for example, using PVC conduits might lead to accidentally piercing them when nailing into the wall later). PVC conduits are cost-effective, easier to bend than metal pipes, and have good insulation properties. Just choose sturdy ones; a simple method to test conduits is to step on them—if they don't collapse, they are good.

Conduit full name "Building Insulated Electrical Sleeve", commonly known as a white rigid PVC conduit, used for anti-corrosion, anti-leakage, and threading wires. Divided into plastic conduits, stainless steel conduits, carbon steel conduits. Used in indoor normal environments and in high-temperature, dusty, vibrating, and fire-hazardous places. Can also be used in damp places. Not to be used in particularly humid, acidic, alkaline, salty corrosive, and hazardous environments.
