Grommets or conduit in metal back boxes?

[gembrain]

I've seen a few comments on failed installs because of lack of grommets - although apparently not a specific requirement as such.

Is oval conduit plastered into chase and fed a little into the back box OK or does one HAVE to cut it just short of the the box and fit a grommet?

Granted it's a sharp edge but where the cable comes in at the top of the conduit is the same.

Thanks

I beleive MDJ was asking for an example when you would use singles within a domestic installation not installed within conduit and just entering a metal box without a metal bush etc? MDJ can correct me if I'm wrong

As long as the wire has its (double insulation) intact & going into the metal back box no grommits are needed .

As some singles dont have a second insulation layer for protection when entering a metal back box then the installation method is completely different so i think MDJ already knows the answerd to his own question as do i . To ask me 4 an illegal example deserves no response. AGAIN ,, ELECSA advised me of this even thou i fitted the grommits ,

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!

Dependant with whom you are reg'd with im sure your answer will be differant ,


If you don't use em the part p police will take you away , NOT ! lol.

Good (or bad) practice has sod all to do with which scam you're registered with!

Put simply, a conscientious well-trained sparky looks after his cables.

Wow, in a domestic premises plus it's cemented in.... that's a bit extreme. We use copex in commercial and industrial, especially in mining applications, it's good but it's expensive.

Plenty classes of kopex available, that looks good. Used to use conduit and flexible tubing on can curing ovens for export. The flexible was anaconda. Never seen anything better on the market in standard or for ease of use. Brilliant stuff.
