Frequently Asked Questions (FAQ)

Q1: Is IEC 60375 mandatory by law?

A: Not usually. However, it is often invoked by higher-level regulations (e.g., Low Voltage Directive in the EU, or OSHA in the US via NFPA 79). If your contract specifies "IEC-compliant diagrams," then IEC 60375 is legally mandatory.

How to Search for the "IEC 60375 PDF" Legally

The most common query is simply looking for a free PDF. However, as a responsible professional, you must understand the legal and technical risks.

• Solid ground if fault current must be immediately and fully available for fast protection and if switchgear can handle fault currents.
• HRG if you prefer operation with single ground faults and want to limit thermal/mechanical stress (choose resistor to limit current to specified amperes; include earth-fault relays).
• Resonant grounding if frequent transient arcing-faults are a concern and capacitive currents are significant—size coil to neutralize capacitive current.
