Type I vs. Type N
Comparing 2 standards across 7 specifications. 7 key differences identified.
Type I, the Australian/New Zealand standard, uses two flat pins angled in a V-shape plus a flat earth pin. China and Argentina use dimensionally similar but genuinely incompatible variants -- Chinese plugs don't physically fit, and Argentine plugs fit but with reversed polarity.
Type N is used in two places -- Brazil and South Africa -- but they are genuinely different implementations, not one standard: Brazil's NBR 14136 uses two different pin-diameter variants and skips a shutter requirement that South Africa's SANS 164-2 (closer to the source IEC 60906-1 spec) includes.
