Hi experts. I'm replacing an older 3-wire cooktop (red, black, bare-metal) with a newer one that has a four wire (red, black, white, green) connection. The wall box has three wires (red, black, white). The installation instructions state:
Since the first sentence of the instructions says "Frame grounded by connection of grounding lead to neutral lead." can I connect the new white (neutral) and green (ground) wires coming from the cooktop to the white (neutral) wire in the wall box?
I can't find anything in the local code that would no permit grounding through the neutral but I'm not an electrician and might be missing something (2010 California Electrical Code Title 24 Sec 3).
I've been reading other similar questions and their answers and it also sounds like there might be an issue with the circuit being compatible with 240V appliances but not necessarily with this 120V/240V - can anyone tell from the wall box wiring whether that's the case?
I've attached pictures of the old wires, new wires, and wall box wires.
Much gratitude!
And the label on the back of the new cooktop states: "For use on 3 wire, 120V/208V - 120V/240V system. 3 wire; 1 phase; 60 Hz" This is a Bosch model NET9652UC which is a hardly-used give-away :thumbup:.
