Electrical Theory & Troubleshooting Skills

A Three Part "Rock~Solid" Electrical Course

Three classes, each lasting four hours.

Electrical theory & troubleshooting skills are thought to be the most important skills for today's technicians. In many trades, electrical problems represent the majority of all service calls (in HVAC, it represents over 70% of all problems). Electro-mechanical systems are powered controlled and regulated by electricity. To be a successful technician, you must understand electricty - how it works, what physical laws control it, how to read and generate electrical diagrams, and how to hunt down difficult electrical problems.

Can you honestly state that you understand line voltage, low voltage, AC circuits, and DCcircuits? Do you understand electrical terms like: STEP UP, STEP DOWN, BUCKING, BOOSTING, VOLTAGE DROP, IN PHASE, OUT OF PHASE, TRUE POWER, APPARENT POWER, and the difference between WATTS and VA LOADS? And what about power systems, do you understand PRIMARY, SECONDARY, HOT LEG, L-1, L-2, L-3, WYE, DELTA, NEUTRAL, and why the HIGH LEG is sometimes called the WILD or BASTARD LEG? Given the requirements of a circuit, do you know how to read and generate pictorial and ladder wiring diagrams? Given only a wiring diagram and a volt meter, can you pin point a failed component in a complex electrical control circuit?

If you don't have a solid understanding of the above subject matter, you need to attend our three part "Electrical Theory & Troubleshooting Skills" course. Every one of the above mentioned topics will be covered in three presentations that will keep you on the edge of your seat. This is a "solid base" course, which means you will be hammered with important technical information time and time again until you know the information cold. After taking this course, you will have ability to (as we put it) "think like an electron" - and yes - you will be able to effectively troubleshoot even complex electrical control systems.
