Side-by-Side Comparison Plug Types

Type N vs. Type O

Comparing 2 standards across 7 specifications. 7 key differences identified.

Comparing:
Type N
Type O

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.

Type O is Thailand's standard, introduced in 2006 -- three round pins whose earth-pin offset happens to numerically match Type B's, letting Thailand's real-world hybrid sockets also accept American Type A/B and European Type C plugs. Pure single-standard Type O outlets barely exist in practice.
