Re: Why Three Rails?

The only electricity in our neighborhood during WWII was 32 volts supplied by a windcharger, with large storage batteries. But I don't remember any electric appliances being used -- just house lighting. Did they make 32 volt appliances?

There were lots of low voltage systems around in rural areas. Many were only 12 or so volts. 32 Volts was also in use.
