Wiring with 2 wires out of wall

try to use black to black: white to red: and green and white to ground.
you may not have a 240 volt supply to this unit. most of the time when you have these color wires that would tell me that it only has 120 volts of power.
you can try to wire it up as described, but it may not heat enough with just 120 volts.
what type of cook top did you replace, a gas unit and now your changing it to an electric one?
if so, then you will have to replace the wiring inside the wall with the proper size wiring to handle the extra current from an electric unit.

I took out an old cooktop which only has the black, white and ground wires. The jennair cooktop with 5 electric elements has black, red, white and ground. how do i connect these together.

sounds like the old one is 110 volts , and the new one is 220 volts. incompatable, as the 220 ones would work, but at half power if you didnt use the red wire. might work fine. omit the red wire and wee what happens

Cooktop WIring

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 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 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.

Jenn air model JED8430bdb


A similar concern on a different model (8230):
To my knowledge, the:
green - ground
white - neutral
black - 120 to ground
red - 120 to ground but between red & black, it should be 240. A Jenn-Air JED8230 requires a 3-wire, 120/240 Volt, 60 Hz Outlet.

Pls consult/confirm with your local electrical utility/codes the availability/applicability of this power/wiring system or reference National Electrical Code, NFPA No. 70

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Elecrical hook-up for cooktop

Based on your appears the Viking unit may NOT comply with UL and the NEC....but implies that some local Codes may permit the suggested connection...and it may indeed be permitted - if the unit actually draws straight 240 and does not require a neutral for 120 volts (some cooktops do need the neutral for 120 volt control switches...such as your Jennair). Code now requires that new 120/240 units that require the neutral (your Viking unit states that it does not) be a 4 wire assmebly....and your unit MAY be an exception to this requirement.

Under those conditions...then it more then likely CAN be connected as you (and Viking) suggest - black to black, red to red,green to white...and insure that the junction box is indeed well grounded to the supply bare ground wire - so that the metal flex will serve as a supplemental ground to the cook-top.The only other consideration will then be - IS the exisiting wire size and breaker that used to supply the Jennair correct for the new unit..? And if so - then you should be all set with your suggested hook-up...but without electrical nameplate data for both units for comparison...I have no way to determine that....both companies make several different models with different power supply requirements.

If the electrical data is compatible between the two units...then you should be all set as suggested - without having to rewire the cooktop.

Hope this helps...please follow-up if you need more details or have new information for me concerning this cooktop.

Wiring installation

You do need a 208/240 volt supply from your service panel. The green is ground, white is nuetral, and the red and black should measure 120 volts each to ground or 240/208 between each other. It is normal for most breaker panels to supply 208/240 between adjacent insulators. If you are only getting 1/2 of that then the circuit breaker may not be straddling the insulator bar but be 1/2 notch out and both breaker pins contacting the same 110 supply.
