Then, Think Electric
France uses 220 volt, 50-hertz electricity. All current in
Western Europe is the same and even the plugs are similar,
so people coming from these countries do not need special
adaptateurs (adaptor plugs). British appliances using 240
volts will not need a transformateur (transformer), but they
will need the continental two-prong plug. Otherwise, if you
are thinking of bringing large appliances with you that run
on 120 volts, you will no doubt need a transformer as well
as the adaptor. Transformers change the voltage, but not
the hertz, so both must be appropriate. Some appliances
will not function and others such as clock-radios may run
too slowly if the hertz are not the same.
Computers and some other electronic devices that
are meant to be used internationally generally switch
automatically from one current to another. Look at the
'brick' (where the power information is displayed on
the cord): if it says 120-240v; 50-60hz, it will switch
automatically. Small appliances such as hair dryers also
come with dual voltage, often with a small switch to turn
to the appropriate setting. For the rest, adaptors and
transformers are available at electronic shops, hardware
stores and department stores.
Electricity is expensive in France and people are used
to doing more with less. This accounts for the minuterie in
the halls of apartment buildings—the button people press
for the hall lights to come on, which only stay lit for a few
minutes before switching off automatically. Nor do gas
stoves waste gas by keeping pilot lights on all the time;
instead people usually light the burner or oven each time
it is to be used. These may be inconveniences at first for
North Americans, but you'll quickly get used to it.
Also, the amount of electricity that comes into your
apartment may not allow you to use a clothes washer and
dishwasher at the same time. When you contact EDF/GDF
(see below) for the initial contract, discuss the level of
electricity you require and the price for each option.
Note that lamps brought from non-European countries
usually needonly an adaptor and a French light bulb. Light
