Excerpt from National Electrical Safety Code About four years ago the Bureau of Standards published the completed text of the National Electrical Safety Code for examination and trial use, an early revision being contemplated. War conditions interfered with this trial, so that the publication of a new edition has been greatly delayed. This revision has now been completed, and the revised code is offered in the form of a handbook for more convenient use. The discussion of the rules has been segregated under a separate cover so as to reduce the bulk of the main volume, and will appear as Bureau of Standards Handbook No. 4. It will be noted that two sizes of type have been used in the text. The larger size has been used for the body of the rules and to give prominence to the more essential parts. Paragraphs which may well be passed over on first reading have been put in the smaller type, even though they sometimes contain important rules. Such paragraphs may contain details of rules, exceptions to rules, alternative methods, suggestions for meeting rules, or mere explanatory notes. Criticism of the rules contained in this edition and suggestions for their improvement are invited and every effort will be made in preparation for the next edition to perfect the rules both in the development of detail and in the modification of any requirements which it is found can be improved.
