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