French Guiana.

220 V · 50 Hz on Type C, Type E, Type D.

As an overseas region of France the wiring is French: 220 V 50 Hz on Type C and earthed Type E sockets, with some old Type D outlets still around. Plugs from metropolitan France and the rest of the continent go straight in; UK and North American visitors need adapters, plus dual-voltage gear for the latter.

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.
