Reserved location for outgoing cables from the distribution box

Outgoing cables from a distribution box are typically routed through reserved knock-outs or gland plates at the top or bottom of the board, with space provisioned to accommodate cable size and termination requirements.Cable Entry PointsDistribution boards are designed with pre-marked knock-outs or gland plates to allow for both incoming and outgoing cables. For outgoing circuits, the following practices are recommended:Top entry: Often used for outgoing cables, especially in apartment or commercial installations, to separate them from incoming mains and facilitate neat routing .Bottom entry: Suitable for larger or heavier panels, sometimes using a trench or false floor to simplify cable access .Gland plate provision: A removable or cut-to-size gland plate should be provided to match the trunking or conduit size, ensuring all outgoing cables can pass through without crowding or damage .Installation ConsiderationsCable sizing: Ensure the knock-out or gland plate accommodates the outer diameter of the cables, including insulation and sheathing, without compromising the IP rating of the enclosure .Separation and organization: Outgoing cables should be neatly organized and tied, avoiding interference with busbars or other terminations .Identification: Each outgoing circuit should be labeled and terminated to the correct breaker, with ferrule identification for clarity .Coordination with other equipment: The reserved location should consider space for cable bends, terminations, and future expansion, and avoid conflicts with adjacent panels or services .Practical TipsPlan before installation: Review the shop drawings and load schedules to determine the number and size of outgoing cables.Use appropriate cable glands: Select glands that match the cable diameter and maintain the enclosure's protection rating.Maintain accessibility: Ensure outgoing cables are accessible for maintenance and inspection without disturbing other circuits.By following these guidelines, the reserved location for outgoing cables ensures safe, organized, and code-compliant distribution board installations while allowing for future modifications or expansions .
