    Wiring through bulkhead

    Am I right in think that (for IVA) if the harness is covered in conduit, where it passed through a firbreglass hole it DOESN’T need a grommet?
    Regards

    No, I'm not "repairing" it, I'm fine tuning its performance.

    Even if it wouldn't be mandatory, I'd still be mounting one, as the trouble to do so doesn't compare to the possible consequences if you dont. Let alone the fearsome thought of a shortcircuit as a potential result of scuffing, but the agony of finding and repair of a cable fault at that spot makes it a no-brainer to me to fit some proper edge protection..

    As standard I would always run in conduit it is good practice . Any bulkheads where possible chaffing and damage to the cable should have protection . If you have a lot of wiring to do a bulk pack

    I had quite a few situations where I couldn’t get a gromit to fit so ran the conduit through the bulkhead and sealed it with sikaflex. Passed the Iva so must be ok.

    they are a pain in the arse to get in, due I think to panel thicknesses, still, only one I couldn’t get in so I’ll seal it in the same manner.

    There are lots of places where a standard grommet designed for fitting into sheet steel won't work where wiring has to pass through a grp bulkhead. On the Crendon the grp is up to 8mm thick in some places.

    Thicker panel grommets are one solution:

    Another way round this is to use one of these, selecting a bit that is the same outside diameter as your grommet:
    https://www.screwfix.com/p/flat-wood...E&gclsrc=aw.ds
    Drill pilot hole, then gently press the flat wood bit into the hole on a medium/slow speed, just long enough to scrape away the gelcoat and some of the grp. Then cut hole for the grommet as normal . The grommet can now be fitted into the resulting recess.
    (Won't work for very thin standard grommets).

    Or use one of these (which is what I used for my main loom): https://www.triggerhandbrakes.com/Bezels1.html

    Bloody hell, those small oval ones are virtually identical to what I made for mine 20 years ago. Someone been copying me!

    These worked for the front bulkhead on the Dax really well:

    8mm panel thickness too, tiny smear of fairy liquid to help install. Like the look of the Trigger ones, could maybe fab them yourself as GDCobra mentions.
