Hi - I'm replacing an old (1980) Thermador electric cooktop with a new Jenn-Air model (it is 240v - I assume, but didnt check, that the Thermador was also 240 since it was a 5-burner radiant cooktop). I have pulled out the old Thermador and disconnected the electrical wiring from the unit (it was hard wired into the unit).
The wiring from the wall is in flexible metal conduit, and has a black, red, and bare copper. The wiring to the Jenn-Air is also in flex metal conduit, but has a black, red, white, and bare copper. You can see my confusion
In the Jenn-Air manual, it says "The neutral of this unit is grounded to the frame through the solid copper grounding wire. If used on new branch-circuit installations (1996 NEC), mobile home, rec vehicles, or in an area where local codes prohibit grounding through the neutral connector, untwist or disconnect the solid copper wire and connect the ground wire to ground in accordance with local coe. Connect the white neutral to the service neutral. Connecet all wires to the branch circuit with approved connectors..."
SO - my question is: what wires go where? I read on another post that i should never connect the white wires to bare ground wires - so where does the mystery fourth wire from the Jenn-Air cooktop go?
Thanks in advance!
