Missing grommets

[skiandy]

Hi,

What are people coding missing grommets on Galv backboxes. I was thinking a Code 2. This makes it a fail now as the Electrical Safety Council recommend that you put "unsatfactory" if there Codes 1 or 2. 80's the orignal wiring checks out with the other tests.

If the cables are sheathed probably a 'code 4' - ' Does not comply with BS7671'

Sorry chaps but could one point out the specific reg for this?

As long as the sheath enters the box before the conductors are visible then its fine.

Its good practice to fit them but if they are missing it doesnt warrant any code at all.

Are we talking surface mounted boxes, or buried in wall types? If they are surface mounted they have to be non-penetrable by a BS standard finger.....

Possible regs 522.8.1 / 522.8.11 although can't say I have coded it before.

Ok guys thanks for your reply, when I did my 2391 we were all told that it was a code 2 by the instructor. The boxes are burried in the wall cable is double insulated where it enters.

Try leaving them out on your inspection, don't think you will be passing somehow

Hey there.

I have to admit I've always coded them as 2. I was taught this also, and Mr NIC said the same at my last inspection.

Cheers.

I don't think I would regard it as unsafe as a 'code 2' down to inspector though.

Here's an ESC PIR Guide:

thats a handy little webite

i think a shallow single switch box 16 mm maybe has no provision for a round grommett due to its oval hole which is allready smoothed and rounded around the edges

Put an oval one in then

I did and i did.

Only on one tho.

Typical he chose that one, but he just confirmed what i said earlier.


Reg 522.8.1(if we are being really picky) does not specifically say that they must be used.

"Failure to provide a grommet whare a cable, such as a twin and cpc flat cable, enters a metal black box is not, in its own right, a deficiency, providing the cable sheath is adequately protected against damage from any sharp edges."

LOL.......like it!
