Ground Continuity Testing with Real Fault Current (NOM-003-SCFI)

Ground continuity testing at 25 A or 30 A real fault current per IEC 60335-1, 62368-1, and 61010-1 for certification in Mexico.

Ground Continuity Testing with Real Fault Current (NOM-003-SCFI)

Validate the electrical safety of your equipment and comply with IEC 60335-1, IEC 62368-1, and IEC 61010-1.

  • Detect hidden ground faults
  • Prevent electric shock
  • Reduce certification rejections

Real risk: why ground continuity tests are critical

Ground continuity testing is a key point in any equipment electrical safety validation strategy. It is not just about measuring resistance: it is about ensuring that, in the event of a fault, current has a safe path to ground.

Without an adequate electrical ground test, risks can arise that compromise both the end user and product performance:

  • Electric shock from accessible metal parts
  • Incorrect operation of fuses or protective devices
  • Overheating at ground connections
  • Progressive damage to electronic boards
  • EMI problems or intermittent failures that are hard to diagnose
  • Rejections in certification processes

In many cases, these faults are not visible in low-current measurements, making an approach more representative of real conditions indispensable.

Solution: earth bond test with real fault current

Our service is based on high-current earth bond testing, performing 25A 30A ground continuity tests in accordance with international standards.

Unlike basic measurements, this high-current earth bond test simulates conditions close to a real fault, revealing problems that would otherwise go unnoticed.

With this approach, it is possible to validate:

  • The low resistance of the protective conductor
  • The mechanical integrity of terminals and joints
  • The system’s ability to carry fault current
  • The correct operation of electrical protection devices

This directly answers the question of how to validate the ground connection of electrical equipment in industrial, electronics, and manufacturing contexts.

Service differentiators

Benefits for your operation

Beyond technical compliance, this service directly affects key business indicators:

  • Less rework in production
  • Lower return rate from electrical failures
  • Greater acceptance by OEM customers
  • Reduced field risk
  • Faster certification processes

Properly implementing ground resistance measurement on electrical equipment not only prevents risks but also improves the perceived quality of the product.

Test process

Our method is designed to be agile, traceable, and standards-aligned:

  1. Analysis of the equipment and its grounding architecture
  2. Definition of critical measurement points
  3. Test execution at high current (25–30 A)
  4. Measurement of resistance and electrical behavior
  5. Generation of a technical report with results and observations

Frequently asked questions (FAQ)

What is a ground continuity test?
It is a test that verifies that all accessible metal parts are properly connected to the protective system, ensuring a safe path for fault currents.

Why use 25A or 30A instead of low current?
Because it detects real faults such as loose connections, elevated resistances, or mechanical problems that do not show up in basic measurements.

Which standards apply to this type of testing?
Mainly IEC 60335-1, IEC 62368-1, and IEC 61010-1, depending on the type of equipment.

Does this help with certification processes?
Yes. Correctly performing IEC ground continuity tests significantly reduces the risk of rejection in formal testing.

What types of equipment should undergo this test?
Electrical, electronic, industrial, and consumer equipment with accessible metal parts or protective earth systems.
