Type I plug & sockets

Two flat blades set in a V shape, usually with a third earth pin. Used in Australia, New Zealand, China and Argentina. Largely isolated — needs its own adapter outside the Type I family.

A plug that fits is not proof of safe use. Check your device’s INPUT label and the destination voltage before plugging in.

Standards reference framework

These IEC publications define the reference framework used to interpret nominal voltage and household plug/socket systems:

  • IEC 60038: standard-voltage reference for nominal supply-voltage families.
  • IEC TR 60083:2015: technical overview of plugs and socket-outlets used in IEC member countries.
  • IEC 60884-1:2022: general safety and performance requirements for household plugs and socket-outlets.

These publications are reference standards, not proof of every live outlet. Country records still require current national, utility, or regional evidence and a visible review date.

Inspect country evidence. The public dataset separates primary, corroborated, partial, and pending claim coverage.

Type I FAQ

What does a Type I plug look like?

Two flat blades set in a V shape, usually with a third earth pin. Used in Australia, New Zealand, China and Argentina. Largely isolated — needs its own adapter outside the Type I family.

Which countries use Type I sockets?

Type I sockets are used in Australia, New Zealand, Argentina, China. Always confirm the local voltage.

Do Type I plugs fit other sockets?

A Type I plug normally fits only a Type I socket; bring a dedicated adapter if needed. Physical fit does not convert voltage.

Choosing an adapter

If your plug does not fit Type I, you need a plug adapter. An adapter does not change voltage.

Safety check: a plug adapter only changes plug shape. It does not convert voltage, so confirm your device label before buying.

Shopping links never change the safety verdict.

Guidance only — not professional electrical advice. Always confirm against your device's label before plugging in. Local wiring (especially in hotels and older buildings) can vary.
