Copper or Aluminum Wire Electrical Connections

Core Issue:

  • Should copper or aluminum wire be used for electrical connections to Wolf appliances?
  • What type of electrical wire is required to install a Wolf product?
  • What kind of wire comes on a Wolf appliance?


Wolf appliances are equipped with copper wire. If aluminum house supply wiring is used:

  • Splice the appliance copper wire to the aluminum house wiring using special connectors designed and agency certified for joining copper and aluminum.
  • These will often be indiated with a "Cu/Al" label.
  • Follow the connector manufacturer's recommended procedure carefully.
  • Improper connection can result in a fire hazard.

Refer to the product installation guide for further information.
