Can two 12-3 Romex cables be used to wire an electrical range which normally use a 8-3 Romex?

Answer 1

for USA, Canada and countries running a 60 Hz supply service.No, the electrical code stipulates that conductor sizes #3 and smaller can not be paralleled. Conductor sizes #2 and larger can be paralled.

You can, if you want to burn the house down 30 minutes after the range kicks on.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 2

No, using two 12-3 Romex cables instead of one 8-3 Romex cable for an electrical range is not recommended. The 8-3 Romex cable is specifically designed to handle the higher power demands of an electrical range. Using two 12-3 cables would not provide the same power capacity and could pose a safety hazard.
