Plug Type O

Plug Type O

Type O is used exclusively in Thailand.

The type O socket and plug, rated at 16 amps, are the official standard in Thailand. The plug system was designed in 2006, but its use is not widespread as yet. It is currently gradually being phased in. The standard is described in TIS 166-2549.

Type O consists of two power pins and an earth pin, which are round and have a 4.8 mm diameter. The power pins measure 19 mm in length, they have 10 mm long insulated sleeves and their centers are spaced 19 mm apart.
