Multi-Standard Cable Sizing Comparison Guide (PDF)
Free download · A4 landscape (2 pages, front + back)
Engineers working on international projects constantly switch between AS/NZS 3008, BS 7671, IEC 60364, and NEC — each with different terminology, table numbering, and methodology nuances. This 2-page A4 landscape guide provides a side-by-side comparison across all four standards: cable sizing workflow alignment (where steps match and where they diverge), terminology mapping (conductor vs cable, ampacity vs current-carrying capacity, adjustment vs derating), installation method cross-reference, voltage drop limits comparison, derating factor equivalences, and fault withstand requirements. This is the single most useful reference for any engineer who works across multiple jurisdictions.

Frequently Asked Questions
Does this cover all differences between the standards?
It covers the key cable sizing differences. For comprehensive standard analysis, refer to each standard individually and use ECalPro's multi-standard calculator.
What paper should I print this on?
Print double-sided on A4 landscape. Laminate for desk use. The comparison tables require colour for readability.
Can I distribute this to my team?
Yes. Especially useful for international project teams. All ECalPro guides are free to print and distribute.
How often is this updated?
Updated when any of the four standards is revised. Current guide reflects AS/NZS 3008:2017, BS 7671:2018+A2, IEC 60364-5-52 latest, and NEC 2023.
