Engineers working in North America often compare IEC 60375 with IEEE Std 280 (IEEE Standard for Letter Symbols for Quantities Used in Electrical Science and Electrical Engineering). While both cover sign conventions, key differences exist:
| Feature | IEC 60375 | IEEE 280 | | :--- | :--- | :--- | | Scope | Sign conventions & reference directions | Letter symbols & units | | Magnetic circuits | Detailed (MMF, flux, reluctance) | Less detailed | | Global adoption | Most of world, plus EU harmonization | Primarily USA | | Passive sign rule | Mandatory for all calculations | Recommended but not strict | iec 60375 pdf
For global projects, the IEC standard is more widely accepted. Many companies maintain both standards in their internal libraries.

Specifies that the standard applies to diagrams for AC and DC circuits, covering reference directions, signs for quantities, and labeling of terminals.
I can summarize the well-known conventions that the standard formalizes: covering reference directions
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.
Perhaps the most famous rule in IEC 60375 is the strict enforcement of the passive sign convention. This rule states that an element consumes power if the current enters its positive voltage terminal. Conversely, if current exits the positive terminal, the element (e.g., a battery or generator) is supplying power. This convention eliminates ambiguity in Kirchhoff’s laws.
