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.

Answer:
Modern people are generally more educated. They have more resources to expend on formal and informal education and more access to sources of information and more free time in which to absorb these sources. They better understand the consequences of their actions. They are generally better fed and less desperate.
Answer:
Foot-in-door technique
Explanation:
The foot-in-door technique is used by many people in society. This technique is meant to when a person does a small request to a person and that person replies in yes, the other person then makes a big request. It is done because people thinking that if you make other people agree at small request then you can make them agree with them at a bigger request.
These techniques are used by the salesperson. Salesperson used this technique so that more people can buy their products. Many people used their knowledge so they could not be persuaded by other people to buy a product that does not need it.
Thus in the above technique, Bart friends used the foot-in-door technique to make Bart agree at bigger requests.
The answer is ensuring that risks are reasonable in relationship to anticipated benefits
When the principle of beneficence is applied to a study involving human subjects it is important to safeguard subjects in the experiment. No matter how important the anticipated benefits may be, the risks have to be reasonable to protect the people involved.
