lead wire

The lead wire is used to determine the specific location of the labeled content. The outgoing lines on the electrical drawings are generally used for pre burying the pre laid conduits, and a bottom up conduit needs to be left for connecting the power lines. For example, for evacuation instructions in the stairwell of a residential building, if it is at the height of the 21st floor, it is necessary to distinguish the circuit, because the evacuation instructions on each floor are fed into the electrical box once, which will waste the conduit and wires. Because the device itself is a low consumption device, some may set up five layers into a circuit. For example, if a circuit box is located on the fifth floor from the first to fifth floors, each evacuation indicator on the first, second, third, fourth, and fourth floors will have an up point on the drawing. Similarly, it serves as an out point. For example, if a unit has a wall lamp outside the door, it needs to be laid with a power supply pipeline to achieve the purpose of powering on the wall lamp
