false because the didn't have a lot of stuff back then
The continuous neutral-current rating be for an autotransformer used to create a three-phase, it must be sufficient to handle the maximum possible neutral unbalanced load. 450.5.
<h3 /><h3>What is meant by autotransformer?</h3>
A grounding autotransformer is used to create a three-phase, 4-wire distribution system from a three-phase, 3-wire ungrounded system.
A three-phase autotransformer is a special type in which common winding is shared by the high voltage and low voltage. Three-phase AC is supplied at primary and output is collected at secondary. Three phase autotransformer is used for such applications where a small voltage is used in the distribution system.
Autotransformers are frequently used in power applications to interconnect systems operating at different voltage classes, for example, 132 kV to 66 kV for transmission. Another application in industry is to adapt machinery built (for example) for 480 V supplies to operate on a 600 V supply.

Geographic isolation could be caused by a number of environmental factors. If a population of people or species live on an island, amongst mountains, in difficult to navigate terrain, or deep into rainforest or forests generally these groups could experience geographic isolation. Geographic largely occurs if a population or group of people or animals live in a remote region of the world that has little access to others due to any number of geographic features.
