    I have run 6mm t and e through the house from the db in the garage on a 32 amp mcb which is rcd protected. the 6 mm cable then goes into the back of an ip66 rated JB on the side of the house. i then intend to run 2 core (live and neutral) 6mm swa up to a workshop using the armour as earth.
    my question is do i need to link the armour to the earth in the 6mm cable coming from the db in the garage and if so how do i do this.

    On the other end, in the cu in the workshop i have got a 20 a mcb for sockets and 6 a for lights. how do i connect the earth block in the cu to the armour from the swa?

    Based on your questions you need an electrician to do this work and also test it afterwards.

    I would strongly recommend you get an electrician in to complete your works.

    No disrespect, but your questions are basic ones however vitally important for the safety of your installation. Failure to have a broad spectrum of knowledge on the safety aspects of your electrical installation can lead to a simple but fatal error, unbeknown to you once installed.

    If this armour isn't correctly glanced your going to end up with a dangerous situation with no earth. If you are unsure how to do this simply do not do it

    You need swa cable glands. They come with the necessary earthing tag to connect the earth cable. Plenty of tutorials on YouTube on how to terminate swa cables correctly.

    Why do some people use 2-core SWA in small sizes and small runs, when 3-core wouldn't cost much more?

    Will you also be acting on the input to fully test and notify this circuit to building control ? Or are you just choosing to ignore the legal and safety aspects of this job in favour of the input that gets it done to your requirements ?

    i appreciate your concern andy78,
    of course it will be signed of and notified so rest assured all in good hands. my brother in law is a fully qualified electrician so he is more than capable of doing this
    and i work under him ;)
