Interior Electrical Systems: Unified Facility Criteria UFC 3-520-01

This UFC 3-520-01 provides design guidance for interior electrical systems. The document has been extensively revised to update the criteria for interior electrical systems. This UFC has also been coordinated with new UFC 3-501-01, Electrical Engineering. UFC 3-501-01 provides overall electrical engineering criteria, including electrical design analysis and documentation criteria. This type of material has been removed from UFC 3-520-01 so that duplication of criteria is eliminated.


Why buy a book you can download for free?

First you gotta find it and make sure it’s the latest version (not always easy). Then you gotta print it using a network printer you share with 100 other people – and its outta paper – and the toner is low (take out the toner cartridge, shake it, then put it back). If it’s just 10 pages, no problem, but if it’s a 250-page book, you will need to punch 3 holes in all those pages and put it in a 3-ring binder. Takes at least an hour. An engineer that’s paid $75 an hour has to do this himself (who has assistant’s anymore?).

If you are paid more than $10 an hour and use an ink jet printer, buying this book will save you money.


It’s much more cost-effective to just order the latest version from Amazon.com
