Use Copper Wire for Hook Up

  1. Do not use aluminum wire for the final connection to the kiln.
  2. Kilns generate constant heat for extended periods, which causes wiring near the kiln to get hotter than in other appliances.
  3. Aluminum wire oxidizes quickly when heated, and aluminum oxide increases resistance, leading to dangerous overheating at the terminal connection.
  4. Overheated connections can cause a fire. Copper, by contrast, resists oxidation and maintains better conductivity.
  5. Local codes may allow aluminum wire to a sub-panel, but it must stay within its temperature rating even when the kiln runs at full power for long periods.
  6. Aluminum wiring was once common in homes but was phased out due to its tendency to expand under load, loosening connections and increasing fire risk.
  7. For safety, always use copper wiring in kiln circuits.
