    you are right. It was black and most of time I have seen black and red. However, I meant black and red which I saw sometimes.

    Is black and red wires without white available? except running through a conduit.

    I may saw 10/3AWG or 12/3AWG and cut out white wire to connect 240V electrical heater.

    Anyways, thank you very much for your replay.

      Yes. I meant black, red and bare wires.

        Typically in the US a water heater is wired with a 10-2 w/ground cable (or equivalent in conduit). The wires are colored black and white, the white remarked to black to show it is a hot conductor. It is certainly code compliant to remove the coloring from the white wire and using it as a neutral. This assumes you replace the circuit breaker with a single pole 20 amp and install a 20 amp receptacle.

        The OP's follow up post saying "your code" leads me to believe he is not in the US. Commonly in Canada a 240 Volt circuit would use a 10-2 cable with black and red colors. According to the NEC you cannot remark a small gauge conductor, but I am not sure of the Canadian code. Might have to ask Red Green if he has any white duct tape

          Yes. It wanted to replace from double pole single through (two 120V, 240V) to sigle pole single through (120V).
