Ukk Junction Box Inner Wire Marking Explained
din power distribution is commonly found inside control cabinets and distribution boxes as a single-pole power distribution terminal, and its internal wiring layout will be specially marked with the functions of each type of wire. Inside earth distribution block equipment, the ground wire is typically marked with the standard grounding symbol ⏚ to indicate the corresponding terminal location.
The compact electrical splitter block equipment design takes into account the access and distribution of multiple branches. Therefore, a dedicated node for PE (Protective Earth) is reserved inside the enclosure, marked by the grounding symbol ⏚, so that construction personnel can quickly identify the grounding connection point. These terminals are often located next to the DIN rail system for easy connection to the overall grounding system of the distribution cabinet.
The prominent marking of the grounding symbol ⏚ allows assembly and maintenance personnel to quickly locate the PE terminal during the assembly process, achieving standardized wiring.
