The table below summarises the plug types, voltage and frequency of electrical current in both Eswantini (Swaziland) and St. Lucia (Winward Islands).
| Eswantini (Swaziland) | St. Lucia (Winward Islands) | |
|---|---|---|
| Plug Types | M | G |
| Voltage | 230V | 240V |
| Frequency of electrical current | 50Hz | 50Hz |
Eswantini (Swaziland) uses Plug Type M.
You will need this adaptor:
Socket Type
(Eswantini (Swaziland)) to Plug Type G
(St. Lucia (Winward Islands))
The voltages found in Eswantini (Swaziland) (230V) and St. Lucia (Winward Islands) (240V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Eswantini (Swaziland) and St. Lucia (Winward Islands) is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
