Folks,

Unit Course in Marine Electricity, 1942, was created during the peak of the massive shipbuilding campaign of WW II. During the war a large number of workers were trained in new trades to meet the increased demand for new labor. This was one of the courses created to prepare those new workers.

Museum ships stabilizing or restoring their electrical systems will appreciate many parts of the manual. Items such as the proper ways of working with armored cable, lacing, etc. are included.

Readers of this manual will also find a Electronic Installation Practices Manual, Chapter 9, Cabling interesting. That manual covers post WW II practice and the two manuals complement each other with more details in one or the other manuals. The Fleetsub Online, Submarine Electrical Installations contains information for both submarines and surface ships.

In this online version of the manual we have attempted to keep the flavor of the original layout while taking advantage of the Web's universal accessibility. Different browsers and fonts will cause the text to move, but the text will remain roughly where it is in the original manual. In addition to errors we have attempted to preserve from the original this text was captured by optical character recognition. This process creates errors that are compounded while encoding for the Web.

Please report any typos, or particularly annoying layout issues with the Mail Feedback Form for correction.

PREFACE

The safety of our country is dependent in large part, during this period of national emergency, upon the production of instruments of warfare that are essential to defense. The training of a great number of individuals for occupations essential to national defense is, therefore, vitally important at this particular time.

The defense training program is maintained under the provisions of Public Law No. 146 by state departments of education in co-operation with the United States Office of Education, through L. S. Hawkins, Director of Vocational Training for Defense Workers. Moneys are available to the states to train large numbers of personnel in defense occupations to meet the demands of local industries having defense contracts. Up-to-date instructional materials are necessary in order that this training may be most effective.

The California Plan of Vocational Education in and for Occupations Essential to National Defense has made provision, therefore, for the development and publication of instructional materials in defense occupations as a part of the state program.

California is actively engaged in training for shipbuilding, which is one of the most important industries in the defense program. This Unit Course in Marine Electricity has been developed by members of the staff of the Bureau of Trade and Industrial Education who are charged with the responsibility of preparing needed instructional materials for this program. Employees of the General Engineering and Dry Dock Company of Alameda, the Moore Dry Dock Company of Oakland, and the Todd-California Shipbuilding Corporation of Richmond acted as a committee for the development of this material. This committee received assistance and advice from H. J. Delaney, Naval Inspector, and from the Electricians Local Unions Numbers 6, 180, 302, 595, and 617 of San Francisco, Vallejo, Richmond, Oakland, and San Mateo, respectively.

Marion A. Grosse, Special Supervisor for National Defense Training, co-ordinated the work of the committee.

The material was edited and prepared for publication by the Special Supervisor for National Defense Training in Charge of Publications, Margaret McKieneavy.

The fine co-operation of the Moore Dry Dock Company in the defense training program is appreciated.

This revised edition includes a supplement covering certain information applicable to naval practices.
