Notes

  1. Common conductors listed, others available such as “A” nickel, 27% NPC, and Alloys.
  2. NS = Not Specified.
  3. Wall tolerances outside of the average wall can still meet UL & CSA requirements based on actual minimum wall and actual conductor diameter.
  4. Please consult factory for verification on CSA 150°C, 200°C, and 250°C temperature ratings.
