Additional Information

BS 6121-1:1989 vs IEC 62444 / EN 62444

Whilst new standards such as IEC 62444 and EN 62444 have more recently been introduced, which CMP Products fully complies with, BS 6121-1:1989 still remains a very important benchmark for users and manufacturers around the world, due mainly to the fact that it is a more onerous construction standard than others published. This will therefore be especially relevant where a national cable gland standard isn’t available. The tables below show the maximum cable entry bore size and tolerances permitted through the range of BS 6121-1:1989 cable gland sizes.

Safety Standards

It is important that workers are able to operate and act in a safe manner, free from harm, and without risk to or from the environment in which they work, or the tools and machinery that they may operate. In the United Kingdom, the Health and Safety at Work Act 1974 lays down the general duties of employers, ‘so far as is reasonably practicable’ to protect the health, safety and welfare at work of employees.

ZEN Insulated Cable Glands

ZEN is available with an insulating arrangement to ensure that no contact is made between the earth circuit carried through the cable armour and the electrical enclosure which the cable enters. This isolation of the cable armour at one end of the cable is sometimes referred to as single point earthing. The ZEN range from CMP however allows more than a single point of earthing and delivering optimum safety.
