Cable entries affect internal layout, wiring space, mounting methods, and protection performance. Before designing, confirm the quantity, diameter, entry direction, and bending radius of power, outgoing, control, grounding, or communication cables.

Surface-mount enclosures can use top, bottom, side, or rear entry based on site wiring, while pole-mount enclosures must avoid entry points being blocked by brackets, clamps, or poles. For outdoor use, verify cable glands, seals, drainage, and IP ratings.

In compact 12-pole enclosures, prioritize cable bending and wiring clearance; in 24-pole enclosures with more devices, prevent cable congestion and impaired heat dissipation. Finalize entry locations during the cutout drawing stage to avoid structural damage from on-site drilling.
