    Hi

    I’ve had some electrical work done. I asked the spark to run some cat 6 cable for me (while he was running electrical cables) and just leave the cat6 cables to be terminated later.

    I’m now looking to purchase faceplate and modules to have these cables terminated.

    Just seen in the specs for the MK K5846WHI module that minimum box depth is 35mm.

    Only the dry-line box he installed is 35mm. All the metal boxes chased into brick are 25mm. Not his fault, I didn’t specify.

    What I need to know are is this requirement likely to be common to all cat 6 data modules? Do I need to remove the backboxes and chase out for 35mm boxes?

    Cheers

    Hi,

    Get a different euromodule!

    The MK one seems to project backwards. Others don't, you won't really notice it's not MK and it will be a lot cheaper! :)

    You could try (states suitable for 25mm boxes):

    Mine (not an MK) would fit in a 25mm back box, but it is a bit tight!

    yes to the above as euro modules are standard at 50x25mm. if the box is "just" too shallow you can get faceplates that stand out a bit

    you can also get slimline modules of 50x16mm so you can get three in a single faceplate,. or even four if you use these

    good luck with wiring four in a single plate though

    Are the boxes likely to be a few mm deeper than the finished plaster finish?

    Don't worry about it! I'm sure it will fit. The low profile ones, look the same as the ones I have, and are very similar to the TLC one I linked to.

    The modules have a cable tie on the back to secure the cable and I think this may be added to the backbox specification. The cable tie isn't strictly necessary (...and even the plastic loops could be nipped off), if you're struggling to fit it. :)

    I've used Connectix Cat5E modules a lot and they are quite low profile - you might try their low profile Cat 6 modules.
    I don't normally even consider the faceplate manufacturer's sockets because they are normally so overpriced. The benefit of Euromod is that any module should fit any faceplate - so I just get the faceplates to match the installation and use the modules we kept in stock (Connectix, at my last job). One of those things that really grates is seeing the data install bear no resemblance to the power install, even on a new installation where it would have been easy to co-ordinate - it's just d.g.a.s. lazyness :evil:

    Also, being a bit pedantic, a single Euro module is 50mm x 50mm. Most data modules are half width at 50mm x 25mm. And if you want to centre a single module in a full module face plate, you need 2off quarter module blanks. One of those things you'll remember when you find the half module blanks you ordered aren't the right thing :whistle:

    Are you aware of any actual standard for Euro module's? My attempts to find one have not been succesful.

    I assume there is one, but I've never looked.
    What I do know is that in the past (pre Euromod), there was no guarantee that modules from one manufacturer would fit faceplates from another.

    Another standard that's around is LJU6C which I've used in the past when using floor boxes without Euromod support. Has some advantages - because each module has it's own hole there is better support in things like flat sheet faceplates than having one big hole.
