This course provides an introduction to exterior electrical power distribution systems for buildings and related infrastructure. The information provided here can be utilized by electrical engineers in the development of the plans, specifications, and calculations, and can serve as the minimum electrical design requirements. It is applicable to the traditional electrical services customary for Design-Bid-Build construction contracts and for Design-Build construction contracts. Project conditions may dictate the need for a design that exceeds these minimum requirements. The design criteria and standards contained within are the minimum requirements acceptable for installations for efficiency, economy, durability, maintainability, and reliability of electrical power supply and distribution systems. The criteria and standards herein are not intended to be retroactively mandatory. After completing this course you will have gained knowledge of circuitry and electrical equipment found to power buildings and how to design an exterior electrical distribution systems for buildings.
