Gland Hole

This is a plain round hole of the order of 20 to 30mm in diameter punched through the end of the enclosure. A stuffing gland will provide a seal through the cable entry hole preserving the IP rating of the enclosure and securing the cable and protecting it from damage on the edges of the gland hole.

Gland Plate

A rectangular plate is bolted to the wall of the enclosure over a large rectangular aperture. The gland plate is to be punched with a hole capable of taking a suitable cable gland for the rated cables. The gland plate may be bolted to the enclosure directly for low IP ratings or with a gasket for high IP ratings.

Cable Entry Box

The cable entry box is an auxiliary enclosure either bolted onto the main enclosure or welded to the side as an integral part of the enclosure. The cable box has a gland plate, usually in the bottom, through which the incoming cable is secured with a cable gland. Two methods can be used to connect to the transformer, (A) Direct and (B) Terminal Plate.

(A) Cable Entry Box - Direct
There is a large aperture between the cable box and the main enclosure through which the incoming cable passes to be terminated on to the transformer.

(B) Cable Entry Box – Terminal Plate
The cable entry box is fitted with a terminal plate over the aperture between the box and the enclosure with stud terminals that pass through the plate. These terminals are already connected inside the main enclosure to the terminals on the transformer. The cable entry box has a front cover allowing access to the stud terminals. The incoming cables are secured through the gland plate with a cable then terminated on the studs in the cable entry box.
