A:Answer It is recommended to plug the unit into its own dedicated 115 Volt, 60 Hz., 15 Amp, AC only electrical outlet. Avoid connecting the unit to a Ground Fault Interrupter (GFI) circuit. If the garage has a GFCI breaker box for the entire building, this unit will need a dedicated non-GFCI breaker in the box for this refrigerator. - Kailey
