This publication provides policy and guidance for design criteria and standards for electrical power and distribution systems. The information provided here must be utilized by electrical engineers in the development of the plans, specifications, and calculations, and must 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. Onsite generation is not addressed by this publication. 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. Course Outline 1. INTRODUCTION 2. ELECTRICAL POWER REQUIREMENTS 3. DESIGN CRITERIA 4. DIRECTIONAL BORING 5. BEST PRACTICES – GENERAL ELECTRICAL POWER REQUIREMENTS This course will give you professional tools that will allow you to better understand the equipment, materials and design for exterior distribution of electrical power.
