                                                           Not knowing where you live, the best place to check for code would be with your city. Most older electric ranges (older than 5 years) probably have 3 wire, most codes now require 4 wire. 4 wire is where the ground wire is connected via the receptacle versus the 3 wire where it is to the unit.
