The table below summarises the plug types, voltage and frequency of electrical current in both Mexico and Cayman Islands.
| Mexico | Cayman Islands | |
|---|---|---|
| Plug Types | A | A, B |
| Voltage | 127V | 120V |
| Frequency of electrical current | 60Hz | 60Hz |
Mexico uses Plug Type A.
In Cayman Islands there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Mexico) to Plug Type B
(Cayman Islands)
Cayman Islands also uses Socket Type A, which is used in Mexico. If using an appliance that has a Type A Plug in the Type A Sockets of Cayman Islands, you will not need an adaptor.
The voltages found in Mexico (127V) and Cayman Islands (120V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Mexico and Cayman Islands is exactly the same (60Hz). Timing devices and appliances that use motors will function as expected under this frequency.
