| Line Design and Staking Level 2
| In Level 2 of the Power Line Design and Staking series, students build
on the foundation created in the prerequisite course, Level 1. This class places emphasis on horizontal and vertical clearances, joint use remedy and make ready, as well as mechanical loading calculations. After completion of Level 2, participants will be able to complete the layout and design of most overhead projects, understand and utilize NESC and sag chart criteria, evaluate and design make ready/remedy for joint use facilities, calculate the mechanical loading effects of line design, and understand conductor blowout and design for/around grain bins. Course manual provided. Final exam. Certificate of successful completion.

| Line Design and Staking Level 3
| In Level 3, attention is given to underground line design basics, understanding how to apply the theories of line design to solve special problems and situations. After completion of this course, participants will understand the effects of physical loads on the distribution system and associated hardware, read DOT projects, class poles, design for special guying situations, calculate sag and create a stringing chart, estimate sag on uneven terrain, and be able to complete the layout and design of most underground projects. Course manual provided. Final exam. Certificate of successful completion. More info

| Line Design and Staking Level 4
| In the final Level 4 course, students focus on line design efficiency, reliability and the aging power infrastructure. Students learn about mechanical loading for multi-circuits, learn about commercial load sizing and the process of calculating loads on manufactured products. Students review the NESC and learn when and how to apply Rule 250 C and D. Classroom discussion includes a brief look at how local requirements and/or RUS standards and bulletins incorporate (and compare to) NESC rules. System protection and balance includes equipment descriptions and purpose, and an overview of smart grid and distribution automation, storm preparation (hardening of the system) and recovery (getting the system back operational). Course manual provided. Final exam. Certificate of successful completion. More info

| Underground Distribution Power Design
| This 2 day course introduces students to the basics of engineering design for underground distribution. The course presents some of the common reasons for designing underground power distribution, advantages and disadvantages of underground vs. overhead distribution and major factors to consider when designing for underground power. Students look at underground cable types, installation, equipment options and applications, and NESC requirements for preparing underground distribution layouts. Students review single and 3-phase transformer sizing and voltage drop calculations. Instruction also includes an overview of protection devices and maintenance issues unique to underground systems. Course handbook provided. More info
