McGraw-Hill's National Electrical Safety Code Handbook
The purpose of this book is the NESC and is provided for the “practical safeguarding of persons during the installation, operation, or maintenance of electric supply and communication lines and associated equipment.” The Code covers electric supply lines and associated equipment and communications lines and equipment. The Code specifies what needs to be accomplished for safety. The Code does not specify how high the poles have to be or where the wires are attached on the pole to obtain the 18.5-ft clearance. Selecting the proper pole heights and attachment heights is a design function. The Code does require that the phase wires be not less than 18.5 ft high (they can certainly be higher).
