ABSTRACT:
A method of sealing an electrical cable (2) into a wall (1) utilises a cable entry gland (3) having axially extending sleeves (3a), and the cable gland (3) is sealed to the cable (2) by means of shrink-down sleeving (9) extending over the sleeve portions (3a) and the surface of the cable (2). The cable gland is sealed into an aperture in the wall (1) by means of two "O" ring seals (5, 6) located on opposite sides of the wall (1) between a radial collar of the cable gland (3) and a clamping member (4). A test port (10) is coupled to the space between the portions of sleeving (9) and the "O" ring seals (5, 6) by fluid passages (8, 7) enabling testing of the integrity of the seal, for example by means of a device according to U.S. Pat. No. 2,145,233.
