    Default 240 Volt Wiring

    Hi,

    If I wanted to make a product with a 240 volt relay which will be controlled with a microcontroller, who/how do I go about getting this certified? Also, I understand an electrician has to assemble this? Are there places in Australia that can do the wiring/assembly? Any pointers in a direction would be great.

    Cheers..

    There used to be few gaps in the AS3000 wiring standards.
    By giving it a plug in lead, you got around the rulings.

    You could still build it this way, then go have a sparky inspect it and place a safety tag on it perhaps....

    I have a 240volt relay that controls my projector screen, i just mounted the whole thing in the switchboard din rail, the trigger signal comes from the projector via a 12v line.

    But if you want to make a "Product", you better go get it engineered first, then start following what ever manufacturing standards you have too.

    How much power does your projector screen draw to have it relay controlled?

    Wink 240 V mains isolation for DIY projects.

    My understanding is that you can do it yourself provided it is not hard wired into service wiring. ie:- via a standard 240 V outlet.
    Of course if you are doing this for commercial sale, it would be a different matter.
    Standard isolation transformers and or opto couplers, as well as insulation, would be the norm to ensure no live chassis or live points are accessible by the user.
    If I'm wrong, I'm sure someone will quote the relevant regulations.

    I have no idea, but the project screen is 240V and the Projector trigger is 12V.
    seemed a simple way to solve the problem.

    There must be ways around it legally, look at the 240V projects that Silicon Chip comes out with (USB power board springs to mind).

    As Beer4Life said, optocouplers etc. reduce the risk to just about zilch...

    Maybe Silicon Chip has disclaimers on its projects, not sure...

    Maybe it you want 100% isolation, use one of the RF 240V switches, big air gap there...
    I'd rather have a bottle in front of me than a frontal lobotomy...

    You dont need a license to install any of the readily available options that even Jaycar sell., no need to re-invent the wheel.
