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