Using none fire rated grommets?

HappyHippyDad · Oct 10, 2019

Is that you fitting it Dusty?
Nice chap but as above why didn't you use the proper grommets for when coming in from above? It needs to be IP4x. I use these EMTFKIT - Cable Entry Kit 8 x 20mm, 3 x 25mm, 3 x 32mm Grommets Kit 17th Edition Amendment 3 - https://www.sparksdirect.co.uk/cable-entry-kit-8-x-20mm-3-x-25mm-3-x-32mm-grommets-kit-17th-edition-amendment-3

Not me happyhippdad…. I swear

I did notice delroy choose to use normal ko box grommets which are not fire proof.
He should have used those skin seal intumescent grommets that you just push the cable through making a tight seal.

(I must admit thou I have used normal blind grommets in the past and just made a small slot in them , but don;t tell anyone)

Havnt watched the video but you dont have to use fire rated grommets on a board, just maintain the ip rating

You are probably correct..

But this then begs the question why are so many sparks gunning in all around the cable entries with fire proof mastic and even using expanding foam to fill in the back knock outs
