Electrical Layout and Estimate Second Edition by Max B. Fajardo, Jr. and Leo R. Fajardo pdf download.
FOREWORD: Electricity is a necessity in human’s daily activity from the simplest household to the more elaborate dwellings, complex offices an even to the most sophisticated buildings; electricity is a basic need for human comfort.
The Electrical Layout and Estimate. is the fourth volume of the author ab9ut. Construction. It was prepared· ·for engineering students, master electricians, linemen and those interested in the art of electrical circuitry and . construction . of the distribution lines.
The book contains information of various wiring materials, receptacles and accessories with tables of technical-data for · ~Y reference. indeed, not only the basic underlying-principles governing electrical layout were stressed but also the generalized concept of good practice in circuitry was incorporated. Basically, the electric circuitry in a house or building comprises the branch circuit, the feeder, and _the main. The National Electrical Code .provides that the braruh circuit that supplies current to lighting and convenience outlets shall be of ample size and rating to carry the ·expected load. It shall at all times be protected with an’ over current protection called. fuse or circuit breaker. Thus; the basic approach to protect the circuitry is to know the load, the size of the ‘wire and the rating of the fuse or. circuit breaker. That is where this book will come in to assist the reader. Presented here are problems of circuitry from the small to . multiple dwellings and commercial load using electric motors. The fundamental process of finding the size of the branch circuit, the feeder and the main including the size of raceway was thoroughly presented in detail. The rating of the over current protective device was given special emphasis in the presentation.. Likewise, the basic fundamental of Illumination was also included because the author believed that lighting is no less important than the circuitry itself. For what use is the circuitry · when lighting was not given importance. It could be well appreciated only through the performance and effectiveness of illumination.
