The table below summarises the plug types, voltage and frequency of electrical current in both Gabon and Oman.
| Gabon | Oman | |
|---|---|---|
| Plug Types | C | C, G |
| Voltage | 220V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Gabon uses Plug Type C.
In Oman there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Gabon) to Plug Type G
(Oman)
Oman also uses Socket Type C, which is used in Gabon. If using an appliance that has a Type C Plug in the Type C Sockets of Oman, you will not need an adaptor.
The voltages found in Gabon (220V) and Oman (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Gabon and Oman is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
