    Default Electrical wiring colours

    My house is wired with red,black green wiring and the bathroom heater which I wish to update,is hard wired. It has a metal shell and 1 green wire is attached to this. I wish to upgrade the heater and have purchased a plastic model that has only 2 wires for connection, brown and blue. . Which wire connects to what and I beleive the green is the earth, what do I do with this.
    I am thinking the green can just be disconnected and taped back out of the way.????
    Brown to red;black to Blue????
    Thoughts please

    Brown replaces the old-style Red for the Phase, or Active connection; Blue replaces the old-style Black for the neutral conductor; and the new style earth lead is green-yellow striped replacing the older green wiring.
    An appliance that is double insulated does not require an earth connection - indeed, it should not have one.

    The electricity is unchanged and makes the same old multi-coloured stars in your eyes when you grab a bit of it.
    When cleaning computer,
    Caution not to water the electric part
    Or the computations will be meaningless.

    Thanx all for the info. It has confirmed my thoughts on the connections and I am really impressed by the swiftness of the answers. Thanx again and if R2x1 is indeed a Penguin, watch out for sharks

    That's certainly one advantage NZ has over Australia, here we can rewire an entire house without a license(but not the meter box), over the ditch you can't change the element in an electric jug without a license.

    Sorry to disagree with you sammo450, but it is not recommended to do DIY electrical work in NZ. Infact an electrical certificate is required for any hardwiring in a NZ house and can prevent a house being sold without this certificate. Imagine a fire is started and the house burns down? The insurance company will not pay out if you do not have certificates for any wiring. My brother inlaw is an electrician and refused to do any wiring in our house (just back from Oz) untill he had his NZ license.
