(I wish this forum had an edit option!!)My message above should have been worded:
Are current kitchen ranges wired in the same manner as clothes dryers? (I realize the difference in amperage requirements.) I will be replacing a 20-year old range for a new one and I wonder if new ranges now use a four wire cable. If so, and your old service is three wire, what should be done with the neutral cable in the stove pigtail?
