CHAPTER 13 



THE UNDERGROUND 

 INSTALLATION OF UTILITIES 



3:30 p.m., Monday, May 24 



The Chairman Mr. CISLER. In our deliberations prior to our 

 meeting this afternoon, we decided to divide our panel presentations 

 in order to recognize the marked distinction between overhead and 

 underground installations in relation to low voltage and high voltage; 

 the responsibilities of various regulatory bodies ; the participation of 

 the equipment manufacturers in the subject; the matter of high- 

 voltage transmission, which is quite a different matter than that for 

 low-voltage distributions and service installations; and finally, the 

 need for long-range planning, which to me is very important, indeed. 



We must make the distinction between overhead installations of 

 the low-voltage distribution circuits and the underground circuits 

 specifically serving the same purpose. There is a great distinction 

 between these and circuits which are for high-voltage transmission, 

 both overhead and underground, which have an entirely different 

 purpose, and which are governed by entirely different techniques and 

 technology, economics, and other matters. 



Mr. NELSON. A revolutionary change has taken place in the pat- 

 tern of installation of low-voltage electric distribution lines during 

 the last few years. Not all of us in the industry, and certainly few 

 people outside it, are aware of the extent of this change or its sig- 

 nificance. I think I can best illustrate what is happening by using 

 as an example my own city of Los Angeles. 



Members of the Panel on The Underground Installation of Util- 

 ities were William M. Bennett, Walker L. Cisler (Chairman), John 

 Dyckman, Ludwig F. Lischer, Rod J. McMullin, Samuel B. Nelson, 

 Joseph C. Swidler, and George L. Wilcox. Staff Associate was Ted 

 Mermel.
