Generator Alternators 101

Course Description

This is a mostly in lab experience with live hands-on equipment in order to give students real world experience in an environment they can practice.  This will be catered towards inexperienced / entry level students who have no alternator experience at all.

This will be specific to machines rated for less than 600 volts AC (low voltage).  This course is also not brand specific – students will be working on Kohler, Cummins, Generac, Olympian, etc.  The goal here will be to bring entry level techs up to speed when it comes to working around various size generators safely, and methodically.  We’ll focus on identifying the different designs and components, and how the voltage regulation system interacts with the generator.

Jamie Claudeo

Course Instructor & Director of Education, On Site Power Academy

Jamie Claudeo Jr. started turning wrenches under his fathers watchful eye when he was just 10 years old climbing in and out of large commercial boilers.  By end of high school he was attending vocational school for electrical trades and before graduating succeeded in taking first place at the state level SkillsUSA competition.  Having a love for engines and machinery, he eventually moved into working on large trucks for Peterbilt after attending Universal Technical Institute in Pennsylvania and Arizona.  After Hurricane Sandy decimated the northeast in 2012 he eventually made his way into Power generation, working for a small company out of NJ.  His strong understanding of both electrical and engines allowed him to move up quickly – taking on large projects, and hard to troubleshoot problems across several states until eventually choosing to start his own business in 2022.

During his free time, Jamie enjoys traveling the world, dark beer, hiking, rock climbing, running and tinkering with old machinery.  On more quiet relaxed evenings you can find him curled up on a giant bean bag chair enjoying a good video game.
