The electrical circuit in the interior of the house is generally concealed, and the box at the switch is the switch box. One is to install switches (fixed) and the other is wiring. Then, the switch box is also called the junction box, the box is not equipped with switches, sockets, only the cover, it can only be called the junction box. The line needs to be branched. Too many pipes turn to facilitate threading, and a junction box is required. Many people think that the switch box is the junction box, in fact, there is a difference between the switch box and the junction box. What is the difference between a switch box and a junction box ? If you have this requirement, you may wish to follow me to understand the difference between the switch box and the junction box . Switch box and junction box What is a switch box What is a switch box? The switch box is the bottom box behind the switch and socket panel. Used in the switch, socket panel, installed in the wall. The switch box is used as the bottom box of switches and sockets, and is calculated according to the number of switch sockets; the junction box is used for the wiring and branching of line tubes, lamps, etc. Generally, the number of lamps + the number of tubes is generally counted (with no turning 30 meters One; 20 meters a turn, 12 meters two turns, 8 meters three turns). What is a junction box What is a junction box? The junction box is used as a transition, and the wire tube is connected with the terminal box. The wire inside the wire tube is connected in the terminal box to protect the wire and connect the wires. This is the junction box. Switch box and junction box difference New material and return material are divided into different methods. First of all, the appearance of the PVC trunking of the product made with the new material is relatively smooth, it does not produce a rough feel, and the product is pure white and does not contain other impurities, and the toughness of this product is very Strong, while the price will be relatively higher than other materials, which is mainly determined by the cost of raw materials. 1. pvc junction box is the length of the pipeline in the electrical piping line. When the pipeline elbow exceeds the specified distance and the number of elbows and the pipeline has branches, the transit transition box must be set. The pipeline is allocated to the load terminal and is reserved. The boxes are terminal boxes. Its role is to facilitate threading, splitting and transition wiring. 2. The terminal box is the installation time. It is used to install fixtures, switches, and sockets. 3. The junction box and the switch box belong to the accessories for electrical installation, and the separate junction box. In the subheading of the switch box installation, it is a main material that is not priced, and the unit price of the main material needs to be input. 4. Whether it is a metal box or PVC plastic box, the H86 type box is widely used at present, and the box surface width is 86mm, and the box depth is 50mm to 70mm (H86*S50.H86*S60.H86*S70.H86*S80 There are 146H*S50.146H*S60). 5. Calculate according to the drawing quantity according to the actual calculation; according to the pipeline branch or return to the pipe must be transitioned, the pipe straight line distance and the number of elbows exceeds the requirements of the specification when the junction box must be added, according to the pipeline conditions and pipelines and bends The head situation is analyzed and calculated, otherwise it is not calculated less. Editor's summary: The above is the difference between the switch box and the junction box, how to distinguish between the junction box and the switch box.
