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