How they differ

  • IEC 60320 C5 cord connector Look for the compact three-contact cloverleaf-style coupler and verify the C5/C6 designation in equipment documentation.
  • IEC 60320 C7 cord connector Identify the two-contact figure-8-style cord connector and confirm the C7/C8 designation in documentation.

Then askIs the cord-side IEC connector the grounded C5 form or the non-grounded C7 form?
