Probable Causes (ranked)

Fix Steps

  1. 1 Check cabinet cooling system — A/C unit, fans, heat exchangers
  2. 2 Clean or replace air filters on panel ventilation system
  3. 3 Verify panel doors are fully closed and sealed
  4. 4 Scan panel interior with IR camera — look for hot spots at connections
  5. 5 Tighten all bus connections — use calibrated torque wrench
  6. 6 If chronic, add supplemental cooling or reduce heat load

Field Trick

An IR scan of your panel connections once a year catches loose connections before they start fires. The ones that burn panels are the ones nobody checked.
