Change the record will ya pal!?
Any PVC sheathed cable entering a backbox where conduit isn't used needs a grommet fitting on the box to keep the cable from being damaged by the sharp edges. You wouldn't have a wire entering a backbox unless in conduit anyway, would you, so what you're saying is actually tripe. Singles of any type (single or double insulated) would be run in conduit, unless I've been doing it wrong all these years......... Or am I missing something??
The grommet protects the outer sheath of the cable, even if that cable has a hundred layers of insulation!
4 pages of posts about grommits in backboxes :-/
i think i've lost the will to live , can someone direct me to the nearest emergency cyanide pill.

Shoot the messenger trolling more like . This is ELECSA advice NOT MINE for fs sake , I fit the dam things as ive said .' no wonder so many just read mostly or bin this site & move on .
You're just bitter because we've covered all the angles and then some without you plus we did it in less than 55 posts.

Just to make the discussion a little more fruity..... what do we make of this?

I think your point is very valid and correct, however I think to comply with section 522 of the regs regarding mechanical protection and stresses covering your backside by adding a grommet, coupler,adaptor or grommet strip for just examples will help you adhere to the regs, and although in theory a double insulated cable entering a metal enclosure if held correctly to avoid possible mechanical damage would be adequate it's just easier to protect the cable where it enters the box and I like your wording on the subject which is much more sensible than the other drivel spouted out by one member here, only enthusiasts and not electricians would consider no protection in metal enclosures IMHO.I had a discussion with an ELECSA assessor about this, he said that there is nothing in the regs that says that grommets must be fitted, he also said that he wouldn't suggest that I stop fitting them.
The edges of the boxes are sharp, you need something to stop them damaging the cable.
Edit:
Just to give a bit more background about the discussion I had ... we were talking about earth tails to back boxes, and whether or not they were required, and he used grommets as another example of something that doesn't have to be fitted but you wouldn't want to not fit.
He definitely didn't suggest that they shouldn't be fitted.
.an exception is the 1/2" back boxes for switches, where the oval cable entry hole is chamfered so as to have no sharp edges.
