Hello.
Thank you for reaching out regarding your Samsung - 6.3 cu. ft. Slide-in Induction Range with Smart Dial, WiFi & Air Fry will work with a 3 prong cord. Regarding your concern, you must use a 3-wire or 4-wire, single-phase A.C. 208Y/120 Volt or 240/120 Volt, 60-hertz electrical system. If the electrical service does not meet the above specifications, have a licensed electrician install an approved outlet. Use only a 3-conductor or a 4-conductor UL-listed range cord. These cords may be provided with ring terminals on the wire and a strain relief device. A range cord rated at 40 amps with 125/250 minimum volt range is required. A 50 amp range cord is not recommended, but if used, it should be marked for use with nominal 13 ⁄8" diameter connection openings. Care should be taken to center the cable and strain relief within the knockout hole to keep the edge from damaging the cable.
• Because range terminals are not accessible after the range is in position, a flexible service conduit or cord must be used.
