The article (Digital Machinist, Volume 9, Issue 1), is called;

“Reading (and drawing) Electrical Prints for Your Machine”,

which was from a real world retrofit of a Bridgeport II CNC. It has 1.3KW DC Servo drives pushed by “CNC Drives” 160V; 35A drives (x3), an “Automation Direct” 3kw VFD spindle drive, an “ESS” with multiple “CNC4PC” breakouts and other components! The Prints for this build are downloadable from Digital Machinist project downloads page, and includes a BOM. The prints are 11” x 17” standard industrial size (PDF Format), so you would need a large format printer if you want to print out a hardcopy set.
