220 V · 50 Hz on Type C, Type F.

Standard post-Soviet setup: 220 V at 50 Hz, unearthed Type C sockets across the older housing stock and earthed Type F in newer buildings. Europlugs fit everywhere; older narrow-hole sockets may resist a modern Schuko plug's thicker pins.

The voltage window

A nominal 220 V supply may legitimately sit anywhere between 198 and 242 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
