Question
Chapter 59, Problem 1SQ
To determine
Write the characteristics of a person who shall operate and maintain electrical machinery.
Expert Solution & Answer
Explanation of Solution
Discussion:
The electrical machinery is usually operated with high voltage and the rotational machines are rotated with high speeds. Therefore, it is required to take much care to install, maintain, and operate the electrical machinery. The improper maintenance of electrical machinery leads to serious and fatal injuries to the person who maintains the machinery.
The characteristics that are required to a person to maintain and operate the electrical machinery are written as follows:
- The person must be a skilled and qualified electrician.
- The person must have a safety conscious.
- The person must be an experienced electrician.
Conclusion:
Thus, the characteristics of a person to operate and maintain electrical machinery are listed.
