Cable Entry Reg

[IAmSparkytus!]

Think I'm going loopy and can't for the life of me find a regulation regarding suitable cable entry to accessories which deems whether nylon glands etc are required.

I've noticed a NAPIT EICR references 522.8.5 but after reading the regulation I'm not sure whether it's actually relevant or not if there isn't any "mechanical strain" involved.

Thoughts?

What type of cable.

 

[IAmSparkytus!]

PVC/PVC. Came across an installation with sockets loose on a suspended ceiling with no nylon glands which in turn has allowed the cables to come back through the knockout hole on the backbox.

HATE HARD PLASTIC BACKBOXES FOR THOSE STUPID KNOCKOUTS AND THE FACT THAT THEY SMASH TO SMITHEREENS IF YOU DROP THEM FROM ANKLE HEIGHT!!!


Edit: Didn't mean to type in capitals there!

526.6 526.8 526.5 651.2 and 522.8.5 should help?

I'd already been through most of those, just looked at the others and im not sure any of them are applicable to my question

There's no mechanical strain on the cables, just poorly made off which they might have gotten away with if stuffers were used and tightened to keep the excess cable hidden away

I might not be making myself clear enough, apologies if I'm not.

I'm basically trying to say, if the cables are pushed back through the hole, and the hole is suitable sized (as they are when they're the knockout type on hard plastic backboxes), is there a regulation saying nylon glands are required or cables should be clipped at point of entry to an accessory to prevent them being pulled back out?

they should be clipeed or otherwise restrained, and the boxes should be secured, not just lying loose on a suspended ceiling.

Agreed but what regulation do you reference for suitablilty of cable entry?

 

[telectrix]

try the one that mentions good workmanship.

Strain relief and IP rating of the accessory spring to mind.
