Realizing the necessity for the sim- plification of electrical specifications so that architects may be assured of qual- ity materials throughout, without the necessity for detailed specifications covering a wide variety of products, General Electric has introduced the G-E Wiring System. The G-E Wiring System is a system of house wiring embodying adequate outlets, conveniently controlled, and using G-E materials throughout. It consists of the following elements: A Safety Meter Service Switch A Safety Panelboard A Bell Ringer Code Wire Metal-covered Conductors (BX or Rigid Conduit) Metal Boxes for Switches, Convenience Outlets and Lighting Outlets A Tumbler Switch at every doorway to control lights Convenience Outlets—a minimum of one for every fifty square feet of floor space Lighting Outlets—a minimum of one for every fifty square feet of floor space. This includes all the essential ele- ments from the service entrance to the point of use and embodies a simple formula for adequate wiring. Specific groups have been selected for houses of varying values, thus maintain- ing a proper relation between the cost of the home and the cost of the wiring. These groups are as follows: Group Residence Valuation I Up to $12,000 2 $12,000 to 18,000 8 18,000 to 25,000 4 25,000 to 35,000 5 35,000 to 50,000 The purpose of this publication 1s to suggest a simplified form of wiring specifications covering different groups of the G-E Wiring System, and to iden- tify the various elements comprising each group. The comfort and convenience which complete wiring provides is the subject of a companion book entitled “The Home of a Hundred Comforts.” In this book the proper distribution of outlets is outlined in principle. Using “The Home of a Hundred Comforts” as a basis for the distribu- tion of outlets and this bulletin for the specification of material, the architect is assured of the two prime requisites in an electrical installation: adequacy and the quality which insures permanence and safety. A GUARANTEE OF EXCELLENCE For the first time since electricity became man’s helpful servant every element necessary for the complete wiring of the home is manufactured by one company ‘and_backed by one guarantee of excellence. Now, after determining the number of outlets desired and their proper eeceiont the architect may be sure of bids which are genuinely competitive. Having specified the G-E Wiring System, he knows that all contractors are basing their bids on identical material; and that variations in bids represent factors which will not affect the quality of the materials used on the job. When the G-E Wiring System is specified, the client is assured of a complete service which will last as long as the house endures; the architect is insured against the use of sub-standard material; his specifications are simplified; he is relieved of the trouble of examining, classifying and specifying the diversified products of a number of manufacturers; and he retains authority over the wiring installa- tion. SPECIAL APPLICATIONS AND CONDITIONS Supplementary paragraphs to cover local con- ditions and special applications can be introduced into these specifications under the captions reading “Exceptions and Additions.” Under these headings also, elements from one group may be transposed to Aotace group when desired. Obviously, a system designed for general applica- tion cannot well include information relating to special applications which are more or less local in character. However, in the interest of the home owner, it is recommended that consideration be given to the specification of wiring for electric ranges, water heaters, electric radiators, intercommunicating tele- phones, etc. Where it is desired to include any of these items, the architect should obtain from the local Power Company the necessary information as to local requirements and methods of installation. Where local ordinances, the rules of the lighting company or the requirements of the connected load conflict with any item of material covered by any of the group specifications in this data book, the electrical contractor will substitute material having local approval; making the selection where possible from other groups shown in the G-E Wiring System Data Book for Electrica! Contractors. ANTICIPATION OF FUTURE NEEDS In many instances, the recommendations in these specifications wil! be found to exceed present practice. Ample justification for this may be found in the difficulties home owners frequently experience in trying to adapt inadequate electrical installations to meet modern needs. The employment of electrical household appli- ances is growing at a rapid pace and, undoubtedly, the next generation will utilize the service of elec- tricity more than ever before. Therefore, in the home being built today, the requirements of the next decade should be anticipated. Architects who do this contribute a genuine service to their clients—a service which will find its reward in the complete satisfaction of their clients. THREE-WIRE GROUNDED SERVICE All G-E Wiring System specifications in this book are based on a three-wire system having an unbroken grounded neutral. This system provides the best distribution of the current load and assures the greatest degree of safety. However, in the groups of materials, alternative catalogue miners are given to cover service switches and panelboards for two-wire systems having both sides of the line fused. HOW TO USE G-E WIRING SYSTEM SPECIFICATIONS A publication similar to this one is available to any reputable contractor upon application. In it the materials comprising the various groups of the G-E Wiring System are identified. Therefore, having indicated the number and the location of outlets on yout drawings, the electrical contractors will then furnish their bids on a special form which will make comparisons simple for you. Send to each electrical contractor, from whom you are soliciting bids, the following material: (a) A set of the drawings showing the outlet distribution. (b) A sheet on which you have transcribed the specification outlined in this book, covering the type of house for which bids are being asked.
