3D printed enclosure for two dimmers


Anth

Question

All,

just made a 3D printed enclosure for two dimmer modules. Designed to be fitted into drywall with plaster to be formed around the edge

 

The lower section holds the two dimmers, bypass blocks and wago terminals for active and neutral. Top section  contains wago connectors for active, neutral and earth as well as the two load actives. Top also has four holes for cables in and out as well as the two load cables.

 

Wires to the Clipsal Saturn switches are connected via plugs and sockets for ease of use.

    No. Not a requirement in Australia. Actually we normally never use boxes in the wall but i prefer for neatness and security of wiring. Should be fine given it takes 180 degrees to melt.

    I am sure no 2 countries have the same regulations :)

    I've never been to Australia but the picture I get from the media is

    1. you are hanging upside down - EDIT: took me a while to find proof of that, finally got it, see (*) below!
    2. you have all the spiders and venomous snakes

    So point 2 may be more important than self extinguishing plastic.

    Okay, I agree it doesn't melt before 180 C (it softens at its glass temperature, probably 120 C-ish) but AFAIK that is not what we guard against. A loose connection might overheat, causing sparks. Those sparks could ignite a plastic and when it burns, it burns like gasoline.

     

    I don't see a particular issue with your setup, though the screw terminals need proper attention while those "wago" connectors are more like "set and forget".

     

    Some countries abolished metal boxes, then brought them back, iirc the UK did that. And IIRC the reason was fire safety.

     

    I follow this UK specific channel:

    He has several talks about safety. At the moment I cannot think which one was about "metal boxes"

     

    So, yeah, it is a tough subject and country specific.

     

    I am sorry if I sounded as if I did not appreciate your project. I do!

     

    Have fun with Home Automation!

     

     

    (*) addendum

  • As an update - a company in Melbourne sells an ABS filament that is compliant to UL94 and is available in white or black. 

    I have printed a couple of boxes to try out.

     

    Thanks,
