Boost 208 Volt Power for Domestic Use

Core Issue:

  • Can a booster or a buck and boost transformer be used to increase 208 volt power to 220 volts?
  • Can Dual Fuel Ranges, Electric or Induction Cooktops, or Wall Ovens use boost transformers to increase power supply when only 208 V power is available?
  • Increase power supply, voltage


The buck boost transformer is the Wolf-approved method for increasing voltage to an appliance.

  • Buck boost transformers should be selected by an electrical contractor for use on any Wolf product.
  • Wolf also offers a 208 V Electric Cooktop for purchase and recommends purchasing this product when using 208 V power supplies for best performance.
    • The 208 V model number is CT30E-208/S.
  • For information on how to check 208 vs. 240 voltage in the home, refer to Determining 208 Volt or 240 Volt Electrical Service.
  • Buck boost transformers are available to purchase online or from local electrical supply warehouses.

Refer to the product installation guide for further information.
