Just a minute
Before you arbitraily re-wire, first determine the load so that you can properly size the run, if its needed.
From the same nomenclatue information will also be a power requirement stated in watts, such as 7KW or 7000 watts. You divide this value by the voltage you have available and this will then determine the operating current of the appliance.
To size the breaker and wire you add 20% to the operating current.
Should it turn out that your existing wire and breaker will work, the red and black are the two hot conductors, the white is the neutral and since your run is in BX the metalic casing acts as the ground. There needs to be a metal box at the appliance recepticle location to which you attach a conductor from the new recepticle grond terminal, to the bonding screw in the box.
