Can SWA cable be taken into an enclosure without gland?
Taking SWA into an enclosure without the use of any form of gland is also unacceptable since the weight and rigidity of the cable means it must have mechanical support and fixing at entry to an enclosure. This is a picture of the seven parts of the somewhat inappropriately named three part gland kit.
