Confused about 3-wire oven hookup

I've wired quite a few appliances over the years, but I'm a bit stumped about what's the right thing to do here. It's a built-in oven, with 4 wires, but the neutral (white) and bare ground are crimped together (by the manufacturer).

The junction box has all 4 wires (black, red, white, bare ground).

The oven manual says, "if local codes permit: Connect the bare oven ground conductor with the crimped neutral (white) lead to the branch circuit neutral (white or gray in color)."

I'm confused here, and I wanted to make sure, because:

1. Presumably, I should connect the oven ground+white to the j-box ground too, right? (since the oven ground is bare wire).

And if so, then...

2. The oven is connected to a sub-panel. In the subpanel, the neutrals and grounds are separated (which I think is correct). But if I hook up the oven as I describe above, I would've just shorted the neutral and ground for that circuit.


I'd expect that the oven's neutral is not current-carrying, since it's crimped to the ground, but in that case, I'd really expected that I would connect the oven's white+ground to the j-box ground, so I'm confused. Any thoughts? Thanks!

 

The manufacturer was planning on having the stove hooked up to older 3 wire house wiring. Since yours is properly done, you can cut the crimp out, wire the white to neutral (which, BTW is current carrying upon return), bare to the ground, black and red to hots. Make sure the grounding wire is connected to the metal box via grounding screw as well.

 

The installation instructions should also tell you how to connect it to a 4-wire feed. You need to follow the instructions in that part.

That's in the J-box on the wall. Inside the oven, make sure the bare ground and white neutral are separated, that the bare ground is connected to the frame of the oven, and that the white neutral is not connected to any of the oven's metal parts.

 

Thanks, guys! Yes, I just re-read the manual and they did say exactly that. D'oh! on my part =)
