Sinopsis
This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 Excerpt: ...route the current may be shut off from the particular section and not interfere with the work of the firemen (this rule also applies to feeders); and they must be safely protected against contact with all other conductors, by separate insulated guard wires directly placed so as to afford full protection from falling or sagging wires. Railway power plants must be equipped in each feed wire before it leaves the station with an approved automatic circuitbreaker or other device, which will immediately cut off the cur rent in case of an accidental ground. This device must be mounted on a fireproof base, and in full view and reach of the attendant. Lighting and power from railway wires must not be permitted, under any pretense, in the same circuit with trolley wires with a ground return, except in electric railway cars, electric car houses and their power stations; nor shall the same dynamo be used for both purposes. Lighting from trolley wires is forbidden because of the danger of introducing into a building a high-potential circuit (often over 500 volts) which has so much capacity back of it and which is thoroughly connected with the earth on one side. Lighting from lower voltage trolley wires is also forbidden on account of the ground connection. Electric equipment of car houses must have the trolley wires securely supported on insulating hangers. Must have the trolby hangers placed at such distance apart that, in case of a break in the trolley wire, contact cannot be made with the floor. Must have cut-out switch located at a proper place outside of the building, so that all trolley circuits in the building can be cut-out at one point, and line circuit-breakers must be installed, so that when this cut-out switch is open the trolley wire will be dead at all poi...
