    Does anyone have a copy of ET208 & 205?

    They are regarding Low Voltage (residential) switchboards and lighting. I rang the ECTI but they aren't available anymore and there are no current replacements available apparently.

    Or could anyone point me in the direction of similarly relevant material? I have the national rules but it is fairly light regarding low voltage stuff.

    The reason I'm asking is that I'm putting in a home automation system that primarily runs off 24V - so switches, sensors, etc.

    Thanks,
    Ted.

    24V is considered ELV (extra low voltage) as it is <50V.
    From 50V to 1000V (and higher) would be considered low voltage.

    I think you will find all that you require in ET101

    A few pointers though:

    ● Read manufacturers data sheets and adhere to them. It is amazing how many people forget this and end up with issues.
    ● Follow best practice in terms of cable segregation.
    ● Power Supply Units can get hot. Ensure that yours had adequate ventilation.
    ● Oversize the panel enclosure to allow for future expansion. This always happens quicker than expected.
    ● Carefully consider the location of the control panel. It should be installed somewhere easy to work on.
    ● I would use relays that have a manual override switch (such as Omron). These make it commissioning / fault finding easier.
