We are remodeling and will be changing out our stove top with a range. The current wiring is bx cable with one red, one black and one white wire. The current breaker is 2 - 2 pole 30 amp breakers. The installation manual states "You must us a 3-wire, single-phase A.C. 208Y/120 Volt or 240/120 Volt, 60 hertz electrical system." The appliance store sold us a 3 pole -4 wire surface mount range outlet (requiring 2 hot wires, one neutral and one ground) and a 4 wire range power cord. Will we be able to utilize the existing wiring for the new range or should we just run new from the box?

Ideally you would run a new line from your panel. It should be a atleast a 8/3 with a groundwire ( 8 is the size of the conducters and three meaning the two hots and the neutral and a ground) also you would need a two pole 40 amp breaker. You could get away with just changing the cord to a three prong cord and hoping your 30 amp breaker will run your new stove. good luck

If you are using a range receptacle you MUST replace the cable. If this is a typical free standing range a 40 amp circuit is the minimum you would want most likely the minimum you could legally use.
