Range Receptacle ?

[Mike01]

For dwelling units I thought I recalled somewhere that the range outlets are required to be 3W+Grd. (2-H/ N / GRD) but cannot find in the code, curious if anyone can help me pinpoint this. thanks.

I think you are looking for section 250.140.

If existing, the cable determines the receptacle and cordset (and jumper use.) If new, four wires.

Until fairly recently, 3 wire range circuits were allowed under certain conditions, in such a circuit the same conductor serves as both the neutral and the equipment ground.
Existing installations may continue in use. 3 pin outlets and 3 core flex being used, with a jumper wire within the appliance that connects together the equipment ground and the neutral.

All new range circuits are required to be 4 wire with 4 pin outlets and 4 core flex, the neutral and equipment ground being seperate throughout.
No neutral/equipment ground jumper should be used within the appliance if it is served by a 4 wire circuit.
