The table below summarises the plug types, voltage and frequency of electrical current in both Nauru and Korea, North.
| Nauru | Korea, North | |
|---|---|---|
| Plug Types | I | C |
| Voltage | 240V | 220V |
| Frequency of electrical current | 50Hz | 50Hz |
Nauru uses Plug Type I.
You will need this adaptor:
Socket Type
(Nauru) to Plug Type C
(Korea, North)
The voltages found in Nauru (240V) and Korea, North (220V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Nauru and Korea, North is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
