Hi Al,
Thank you for reaching out and we hope you are in good health. We appreciate your interest in Samsung home appliances, specifically with Samsung - 30" Double Wall Oven with Flex Duo, Steam Cook and WiFi - Stainless steel.
The home appliance uses a hard-wired electrical connection that uses a range of Amperes (between 20 - 50), depending on the KW rating.
I have shared the user manual link below. Please access the link and turn to pages 9 - 10, 13 - 14 for the electrical connection.
