71. Wooden Mouldings. a. Must be made of well seasoned lumber, and be treated inside and out with at least two coats of white lead or shellac. b. Must be made of two pieces, a backing and a capping, so constructed as to thoroughly incase the wire and provide a one-half-inch tongue between the conductors and a solid backing which, under grooves, shall not be less than three-eighths inch in thickness. c. Where moulding is run over rivets, beams, etc., a backing strip must first be put up and the moulding secured to this. d. Capping must be secured by brass screws. 72. Motors. a. Must be wired under the same precautions as with a current of same volume and potential for lighting. The motor and resistance box must be protected by a double-pole cut-out and controlled by a double-pole switch, except in cases where one-quarter horse-power or less is used. The leads or branch circuits should be designed to carry a current at least fifty per cent. greater than that required by the rated capacity of the motor to provide for the inevitable overloading of the motor at times. b. Must be thoroughly insulated. Where possible, should be set on base frames made from filled, hard, dry wood and raised above surrounding deck. On hoists and winches they shall be insulated from bed-plates by hard rubber, fiber or similar insulating material. Shall be covered with a waterproof cover when not in use. . Must each be provided with a name plate giving maker's name, the capacity in volts and amperes and the normal speed in revolutions per minute. AMERICAN INSTITUTE OF ELECTRICAL ENGINEERS. NEW YORK, September 29th, 1897. The 118th meeting of the INSTITUTE was held this date, at 12 West 31st Street, and was called to order by President Crocker at 8.20 P. M. THE SECRETARY:-At the meeting of the Executive Committee of the Council, on September 15th, the following associate members were elected: Name. BLACK HOWARD D. Address. Salesman, Blackall & Baldwin, 7 BLACKALL, FREDERICK, S. Selling Agent, Crocker-Wheeler GRAVES, CHAS. B. STOUT, GEORGE H. Total 4. Representative of Crocker-Wheeler Endorsed by. S. S. Wheeler J. R. Lovejoy. C. S. Bradley. THE PRESIDENT:-Gentlemen, as I appear here rather as an advocate than as a judge, it is proper that I should not preside at this meeting. It may be necessary for me to take part in the debate. My connection with this National Conference on Standard Electrical Rules ante-dated by more than a year my election to the presidency, and it was not practicable to sever that connection-certainly not before this meeting. Therefore I shall call upon Mr. Lieb, one of our Managers, to kindly take the chair. Mr. Lieb then took the chair. THE CHAIRMAN:-We will begin the presentation of the matter that is to come before the meeting this evening by the reading of Dr. Crocker's report. The Secretary read the following: AMERICAN INSTITUTE OF ELECTRICAL ENGINEERS. REPORT ON THE "NATIONAL ELECTRICAL CODE." The National Conference on Standard Electrical Rules met in New York City on March 18th and 19th, 1896. This body was composed of delegates representing the various Electrical. Insurance, Architectural and allied interests, and had for its object the adoption of one Electrical Code to take the place of the many conflicting Codes then in existence. Representatives of the principal electrical companies were invited to attend the Conference but it was decided at the meeting that these delegates should be made Associate Members and that the voting membership should be confined to the following Associations : American Institute of Architects. AMERICAN INSTITUTE OF ELECTRICAL ENGINEERS. American Society of Mechanical Engineers. American Street Railway Association. Factory Mutual Fire Insurance Companies. National Association of Fire Engineers. National Board of Fire Underwriters. National Electric Light Association. Underwriters' National Electric Association. As a result of the labors of this Conference, acting in co-operation with the Underwriters' National Electric Association, a revised set of rules has been formulated to which the name National Electrical Code" has been given, a copy of which is submitted herewith. This Code has already been adopted or approved by the following bodies: Factory Mutual Fire Insurance Companies. National Board of Fire Underwriters, National Association of Fire Engineers. The influence already exerted by the INSTITUTE in this matter has been most important; in fact, it is no exaggeration to say that the Conference would have failed to accomplish its object had the INSTITUTE held aloof from it. The representative of the INSTITUTE was appointed Chairman of the Committee on Code, which performed the actual work of revising the Rules. The New Code contains many amendments in regard to the technical requirements, and in form it has been entirely revised. The latter fact is particularly important, as previous codes had become a patch-work containing many repetitions and interpolations. This result alone is a sufficient reward for the labors of the Conference. It is not claimed that the Code is perfect, but it can be said that each word in it was carefully considered by a number of men representing the most diverse interests and points of view. If amendments are required in the future they can easily be made, the new arrangement of the Code being specially designed to enable this to be done without injury to its general form. In view of the very great advantages to be obtained by the general adoption of one uniform Code for the whole country; the fact that it has already been adopted by the most important bodies represented in the Conference, and in order to complete the powerful and beneficial influence which the INSTITUTE has already exerted in this matter, your delegate earnestly recommends that the INSTITUTE give its approval to the “National Electrical Code." This action need not be an adoption of the Code which would be in any way binding upon the individual members of the INSTITUTE. All that is necessary is that the INSTITUTE should approve the Code as representing uniformity and co-operative action. One of the most important functions that the INSTITUTE can possibly perform is the encouragement and securing of the very uniformity which this Code so well represents. NEW YORK, Sept. 15th, 1897. Respectfully submitted, FRANCIS B. CROCKER, Delegate. THE CHAIRMAN:-Gentlemen, you have heard the report read by the Secretary in which this new code is submitted for your considerat on, and I will now declare the discussion open. I think it might be well, and also as a recognition of the labors which he has bestowed on this subject, to ask Mr. William J. Hammer if he will kindly open the discussion. MR. HAMMER-I would rather have kept quiet just now and listened to others. I would like to say however, that when Dr. Crocker prepared his report as delegate from the INSTITUTE, there were only four names which appeared of associations which had already considered and adopted the National Electrical Code, and at that time I sent a letter to the official delegates of the other five associations to find out what action if any their associations had taken, and how soon they proposed to take action, in order that I might, perhaps, refer to it here. I at once heard from Captain Brophy that his association, that is the National Association of Fire Engineers, had unanimously adopted the code, and the notice was received in time to add it to the other four associations which had already adopted the code. I have this evening received a letter from the representative of the American Institute of Architects, whom I had seen personally and who assured me that the matter would come before the Executive Committee of his association, and he gave most positive assurance of its adoption by the American Institute of Architects. His letter, which I received this evening, says: "Your favor of the 23d received and contents noted. We did not succeed in getting a quorum to attend the last Executive Committee meeting of the American Institute of Architects; but our annual convention is to be held in Detroit next week, preceded by the Board of Directors, at which time action will be taken upon the National Code. I have written a report to the convention, and also to the Directors on the subject which I shall present at the meeting. Yours very truly. Alfred Stone." And I might say that I also received this afternoon a letter of similar import from Mr. Frank R. Ford, delegate of the Ameri |
