Scope

Insulation-resistance test-voltage source-navigation only. It does not publish insulation-resistance test voltage values, acceptance thresholds, pass/fail criteria, procedure steps, equipment lists, or compliance decisions.

Lookup table

Point to public source pages relevant to insulation-resistance test-voltage review.

Scroll sideways to keep row labels aligned with hidden columns.

Lookup basis uses manufacturer test-instrument guidance, asset manufacturer instruction navigation, and standards source-owner navigation.

Notes
  • Check table values only for source-navigation and current source-area review.
  • Confirm the current source document, product marking, utility page, or authority guidance before any design or field decision.
