    Folks,
    I have some 3 core 1.5 SWA left over, armoured, is this only good enough to power lights, or could it power auto gates if needed. I want to run it about 40 meteres from house. Just wondering.

    I think you will find that the volt drop will be excessive, but that will depend on the size of the load.

    Also you'll need to satisfy fault loop impedance values

    Basically you have not given enough information to answer the question!

    It is not possible to size a cable correcly if you do not know what size the load is!

    I think you should get an electrician to look at it.

    If it's home gate, not industrial 3x1.5 it's ok Sliding motor take max 3 A when it's working, swing gate take max 6A on work, 3 A each motor. And you open gate few times per day.
