To complying with changed Codes (effective in 2002 ) regarding stoves, ovens and dryers. You will need a 120/240 volt 4 wire 40 amp and 50 amp circuit. This
Decades ago it was permitted to use a 3 wire system (having two 120 volt hots (Black and Red) and 1 combination ground/neutral wire) (green and white) to serve stoves, cooktops, ovens and dryers.
The Code change now requires all stoves and dryers in NEW construction to have the 4 wire set-up (now having two 120 volt hots, 1 white neutral and one green or bare wire ground).
Existing wiring is grand-fathered under the Code change.....I advise you to change the feed wiring over to the the 4 wire set-up...
because - as with ALL Code changes in the past...it will eventually become mandatory for all stoves, ovens and dryers as the grand-father clause drops off. By complying now...
BUT the wiring will need to change to 8/3 with ground. (having 4 wires inside one outer jacket).This is the primary reason for the Code change....to provide a greater margin of safety to the user.
I can NOT recommend the 3 wire hook-up...the 4 wire provides a seperate ground and neutral -
which makes the chance of a user shock when touching the metal frame (from an internal fault in the oven) much less likely then the old 3 wire set-up....
which did NOT have the seperate ground and neutral.
