Why is holding both meter probes on a high-voltage circuit a potential hazard?

  1. A hand-to-hand path is the most dangerous
  2. Probes always conduct heat to the hands
  3. The meter supplies the shock current itself
  4. Both hands read the AC value together
Show answer

Correct answer: A hand-to-hand path is the most dangerous

Current through the chest between the hands is the worst path, particularly if probe insulation is cracked.
