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

Surface-mounted enclosures allow top, bottom, side, or rear entry based on site wiring; pole-mounted enclosures must prevent brackets, clamps, or poles from blocking entries. For outdoor use, verify cable glands, gaskets, drainage, and IP ratings.

In compact 12-pole enclosures, prioritize cable bending and operating space; in 24-pole units with dense equipment, avoid cable bunching and heat dissipation obstruction. Finalize entry positions during cutout drawings to prevent structural damage from secondary field drilling.
