Every product, machine, and electrical device has precautions before use, and cable distribution boxes are no exception. Here are key points to note before using them:
1. Check Grounding Connections
Before using the cable distribution box, first verify that the connection between the grounding wire of each branch cable and the box’s grounding terminal is secure. Ensure there are no missing connections for any branch cable and that every wire is tightly connected. After confirming the connections, pay attention to a detail: the connection point between the box’s outer shell and the direct connection line of the ground grid should be prominent and visible at a glance, clearly indicating it is a grounding point. A visible grounding point serves as a reminder that no excavation is allowed near the cables. Additionally, if any connection issues arise with the cable distribution box, the prominent grounding point enables quick identification of the cause for repair and handling.
2. Conduct Post-Installation Testing
Even after completing the installation of the cable distribution box, it cannot be put into full use immediately. Safety and electrical operations are of utmost importance, so in accordance with relevant test standards and conditions, tests must be conducted on the cables and components together.
