The voltage in Brasilia’s electrical grid is 220V.
The Brazilian standard of plugs and sockets establishes that devices and receivers must have two or three round pins. The third pin works as a ground wire and prevents electric shocks and short circuits. Sockets have three holes of 4 mm for devices with up to 10-Ampere nominal current, or of 4.8 mm for equipment that work within 20 Ampere.
