June 26, 2024 8am-4pm CST Fundamentals of Off-Highway High and Low Voltage Design

Course Overview

This course presents fundamentals in electrical system design based upon the requirements of the customer and product. Reviewing the machine system architecture aids in identifying critical system components within that architecture. Fundamentals in electrical system calculations critical to component selection are reviewed. Various construction materials and necessary design factors for routed systems are then presented with a capstone project reinforcing these concepts.. Throughout the course, standards from various organizations including (SAE, ISO, IEC, and EC) illustrate their impact on the electrical system design. Supporting each module is an interactive questionnaire that will test the participants’ understanding of the presented materials.

Learning Objectives

  • How machine purpose and utilization drives systems design
  • How high-level system design impacts routed systems design
  • What are some key electrical system components – low voltage / high voltage
  • What are some key factors to consider when specifying cables, and connectors
  • What is the SAE J1939 standard  and why is it so important to off-highway machine design
  • What are the major electrical failure modes , what  causes them and how can they be prevented
  • Who are some of the key organizations driving electrical system standards / regulations

Target Audience

This course was developed for project stakeholders, engineers and technical staff tasked with specification and design of electrical systems.


The in-person session will be held in the training facility at RFA Engineering, 12986 Valley View Road, Eden Prairie, Minnesota 55344.


This is an entry level technical course which includes equations which need to be solved with algebra. Individuals with some prior experience in electrical system design may find this course easier but there is something for everyone to learn.
