Q&A By Frank Bertie NAPIT Group Technical Director - Q: Do I have to provide grommets in metal back boxes of sockets and switches?
A: Grommets or some other method of protecting the cable from the effects of abrasion from the sharp edges of metal consumer units, enclosures or back boxes.
Care should be taken when the protection is installed as often during the installation process the grommets can move and either fall down or pull up leaving the cables open to damage. This is even more important when using grommet strip as this is more susceptible to movement.
