The table below summarises the plug types, voltage and frequency of electrical current in both Singapore and Oman.
| Singapore | Oman | |
|---|---|---|
| Plug Types | G | C, G |
| Voltage | 230V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Singapore uses Plug Type G.
In Oman there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Singapore) to Plug Type C
(Oman)
Oman also uses Socket Type G, which is used in Singapore. If using an appliance that has a Type G Plug in the Type G Sockets of Oman, you will not need an adaptor.
The voltages found in Singapore (230V) and Oman (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Singapore and Oman is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
