Hi Katherine,
We are happy to share the information regarding your question about this Samsung cooktop.
For electrical requirements, use eight-gauge solid copper wire.
We also recommend having your cooktop's electrical wiring and hookup connected by a qualified electrician. After installation, have the electrician show you where your main cooktop disconnect is located.
Refer to the installation manual on page 3 (For your Safety), page 6 (Electrical requirements), page 8 (Make electrical connection), and page 9 (Note) for reference: https://downloadcenter.samsung.com/content/UM/202212/20221214140621135/Induction_Install_NZ30K7880U_NZ36K7880U_DG68-00827A-05_EN_MES_CFR.pdf
