I am installing a new range. I have a three wires coming out of a metal conduit which is properly connected to a 60 amp breaker. I have a three wire cord and a grounded surface mounted outlet. I assume that the ground will connect through the metal conduit. THis will ground the outlet. How do I assure that the range is grounded? I also have a four wire cord that came with the range that has a dedicated ground wire. Should I get a four prong surface mount plug? If so how do I ground that outlet as there are only three wires in the conduit? A bit confused.

Attach to the metal box for the ground. Measure from hot to ground to verify ground is intact.

If there is no path for grounding then install GFCI recepticals for safety, which will allow you to use grounded equipment.

Well, since it's conduit... can you pull a ground wire? It's surely the safest, best alternative to relying on conduit connections for a ground.

Ssnook, your at it again, answering year old questions.
And your answer makes no sense, since the question has to do with a range circuit.
Are you suggesting to use a 40 amp GFI receptacle? Does not exist.
120 volt 15 or 20 amp GFI receptacles are allowed to be used when an equipment ground is not present, however, that does not create an equipment ground for grounded equipment, and the device or any receptacle protected by that GFI must be labeled "No Equipment Ground".
