The table below summarises the plug types, voltage and frequency of electrical current in both Kazakhstan and Bulgaria.
| Kazakhstan | Bulgaria | |
|---|---|---|
| Plug Types | C | C, F |
| Voltage | 220V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Kazakhstan uses Plug Type C.
In Bulgaria there's more than one socket type in use.
You will need this adaptor:
Socket Type
(Kazakhstan) to Plug Type F
(Bulgaria)
Bulgaria also uses Socket Type C, which is used in Kazakhstan. If using an appliance that has a Type C Plug in the Type C Sockets of Bulgaria, you will not need an adaptor.
The voltages found in Kazakhstan (220V) and Bulgaria (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Kazakhstan and Bulgaria is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
