More later!

120/208 Volts was also used in Bucharest. 220/380 Volts where introduced in the villages (nowdays most of them are part of the city) sorrounding Bucharest. Later, the voltage was switched in Bucharest too. So when the voltage swtiching was made, I wonder if they made a recoling ot the motors of the elevators from the buildings who previously used the lower voltage.
