The table below summarises the plug types, voltage and frequency of electrical current in both Norway and Tonga.
| Norway | Tonga | |
|---|---|---|
| Plug Types | C, F | I |
| Voltage | 230V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
In Norway there's more than one plug type in use.

The voltages found in Norway (230V) and Tonga (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Norway and Tonga is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
