Free download · 85 × 54mm (credit card size)
Working on international projects means dealing with different cable color standards in every country. This pocket reference card eliminates confusion by showing phase, neutral, and earth wire color codes for 10 countries and standards side by side: IEC 60446 (international), AS/NZS 3000 (Australia/NZ), BS 7671 pre-2004 and post-2004 (UK), NEC 120V and 277/480V systems (USA), plus India, Middle East, China, and Japan. The reverse side covers important notes on local amendments, legacy installation colors you might encounter on older sites, DC system color conventions, and the timeline for harmonised color adoption. Whether you're an engineer managing multi-country projects or a contractor encountering unfamiliar wiring, this card gives you instant clarity on what each wire color means.
