The table below summarises the plug types, voltage and frequency of electrical current in both St. Lucia (Winward Islands) and Bhutan.
| St. Lucia (Winward Islands) | Bhutan | |
|---|---|---|
| Plug Types | G | D, F, G, M |
| Voltage | 240V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
St. Lucia (Winward Islands) uses Plug Type G.
In Bhutan 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
(Bhutan)
Socket Type G
(St. Lucia (Winward Islands)) to Plug Type F
(Bhutan)
Socket Type G
(St. Lucia (Winward Islands)) to Plug Type M
(Bhutan)
Bhutan 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 Bhutan, you will not need an adaptor.
The voltages found in St. Lucia (Winward Islands) (240V) and Bhutan (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 Bhutan is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
