(Summary description)The difference between wall switch socket junction box and junction box: the plastic bottom box is located in the wall, while the junction box is on the surface of the wall. 1. The junction box is the crossing transition box that must be set when the length of the pipeline in the electrical piping line, the distance and number of elbows of the pipeline exceed the specified distance and the number of elbows, and the pipeline has branches. The box from the pipeline to the load terminal is reserved, which are all junction boxes. Its function is to facilitate threading, branching and transition wiring. 2. Switch box, socket bottom box and lamp box are terminal bottom boxes for these three kinds of installation. They are used for installing fixed panels and wiring in the box when installing lamps, switches and sockets. 3. Although the junction box and switch box belong to auxiliary materials in electrical installation engineering, they are in separate junction boxes In the sub item of installation quota of switch box, it really belongs to unpriced main materials, and the unit price of main materials needs to be entered. 4. Junction box and switch box, whether metal box or PVC plastic box, are widely used in installation engineering at present, that is, the box surface is 86mm wide and the box depth is 50mm. 5. When calculating the junction box, the lamp cap box, socket box and switch box are calculated according to the actual number of drawings. The sub junction box must transition when the pipeline branches or returns to the pipe. When the straight-line distance of the pipeline and the number of elbows exceed the requirements specified in the specification, the junction box must be added, and finally calculated according to the actual number.
