The electricity supply in Austria is provided in alternating current at 220 volts, 50 Hertz. Outlets have a maximum connection load of 2,000 watts and are 2-wire single phase systems.
Appliances for 110 or 120 volts at a maximum charging rate of 20 amperes (approx. 2,000 watts) may be operated by using stepdown transformers of 220/110 volts connected to each outlet, provided that these transformers have two separate windings which will eliminate any danger of electric shock. Such transformers, which are required by the Austrian Electric Safety Code, are available but only at high cost. American lamps can be used by simply inserting adequate bulbs.
