This part 783 discusses the meaning and application of the exemptions provided in sections 13(a)(14) and 13(b)(6) of the Act. The provisions of section 6(b)(2) of the Act, which relate to the calculation of minimum wages and the hours worked by seamen on American vessels, are also discussed in this part. Other provisions of the Act are discussed only to make clear their relevance to these provisions and are not considered in detail in this part. Interpretations and regulations also published elsewhere in this title deal in some detail with such subjects as the general coverage of the Act (part 776 of this chapter), methods of payment of wages (part 531 of this chapter), hours worked (part 785 of this chapter), recordkeeping requirements (part 516 of this chapter), and qualifications for exempt executive, administrative, and professional employees (part 541 of this chapter). Reference should also be made to subpart G of part 570 of this chapter which contains the official interpretations of the child labor provisions of the Act. Copies of any of these documents may be obtained from any office of the Wage and Hour Division.
