New Electric range, old wiring in house

I just bought a new electric range to replace my stovetop range. The new range calls for a 40 amp circuit (4 prong). The current stovetop range is hardwired, using non-metallic 10-3 wiring and a 40 amp breaker. Will my existing wiring work? Will I need to run new cable?

Thanks in advance,

If this was a range circuit then the 40 amp breaker or the cable was incorrect in the original installation. 10 awg maximum breaker size is 30 amp. for this application.
You will have to run a new cable. You will need 8/3 with ground (4 WIRE) large appliance cable minimum. You can use the 40 amp breaker already there if it is a double pole designed to disconnect both hot legs. This new range since it is four wire has both 120 volts and 240 volts. Also some suggest upsizing to 6 awg still using the 40 amp breaker thus giving you the capability to install a bigger Kilowatt range in the future and only needing to change out the breaker. Is this going to be a hardwire or cord and plug installation? Post back with what you need to know and answer the questions and the forum will get you fixed up......RL
