Electrical Questions? Ask an Electrician Online.
Hello.....my name is XXXXX XXXXX I will be happy to assist you with your electrical question. My goal is to exceed your expectations on Just Answer!
1) A stovetop is 240 volts AC and only requires 2 hots from the breaker and a ground.
2) If there is no clock or timer on the stovetop, a white neutral wire is not required, only the 2 hots feeding from a double pole breaker is required.
3) Most likely, the diagram is showing the connection used as 2 wire Romex cable with the black and the white both terminating on the double pole breaker.
4) For your connection, terminate 1 black and 1 red from your breaker to the same colors on the stove. You should have either a bare copper or a green wire from your electrical panel. The stove top bare will splice to either the green or a bare copper ground wire.
Hope this helps.........If you have any additional questions, let me know and I'll be glad to answer them for you.

Kevin: from my breaker I have 3 wires: Red, Black, and Black. No green or bare wire (that would make things easy).
K: I went to Ace and purchached a non-contact voltage tester. Unfortunatly, all the wires from the junction box are so close, the beeper goes off for all of them. One black wire seems stronger. I'm Just going to call an electrician. Have a good day.
James..... a non-contact tester will not accurately test the wires. You need a 2-prong AC voltage tester or an AC voltmeter to accurately test the hot wires.
OK: Both the black wires read 120 V and the red wire reads 0 V.
So: Breaker black to stove black, breaker black to stove red, and breaker red to stove bare. Correct?
The red wire tested 0 volts while both black wires tested 120 volts. Does this not make a case for the red wire being "ground"? There is probably another junction box behind the oven. Getting to that requires removal of oven which is more than I'm willing to do right now.
1) No problem, was just trying to make it easier for you to match color for color on the stove. As long as the 2 blacks each measure 120 volts to neutral or to ground, then connect the 2 blacks to the double pole breaker. Make sure the red is not connected to a breaker in the panel and connect it to the bare copper ground wire. Put some green tape on the red wire to re-identify this as a ground wire. Connect the red to an equipment grounding bar inside the panel.
2) The red should never be ground. Only greens or bare copper are ground. Whoever originally wired using 2 blacks and 1 red was incorrect since a ground wire is missing. Since you do not have any other choice, then use the red as ground, but make sure to re-label it with green tape.
James..... thank you for the positive rating.........much appreciated!
If you have any other questions, just let me know.
Take care and have a great weekend............Thanks..............Kevin!
