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 mater, 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.

Electrical Terminology
· Understanding voltage, current, resistance, power
· Understand differences between Power & Energy
Understanding the Important Relationships of Voltage, Current, Resistance, Power
· Study what will happens to the remaining variables when one variable changes
· A "Wow ... this finally makes sense!" review of ohm's law
AND VERY IMPORTANT: Answer the all important troubleshooting question:
· Where's the volts?

Alternating Current
· What is alternating current
· Sources of alternating current
· Uses of alternating current
Direct Current
· What is direct current
· Sources of direct current
· Uses of direct current
Single Phase & Three Phase Power
· Understand transformers ~ multi-tap & center-tap windings
· Understanding the difference between Watts & VA loads
· Understand single phase and three phase power circuits
· Understand voltage differences between "Delta" & "WYE" three phase supplies
· Examine the internal components of single and three phase panels
· Understand proper methods of testing single and three phase panels
Wiring diagrams & troubleshooting techniques
· Understand Line ~ Load ~ Control (LLC) and control strategies
· Read pictorial and ladder wiring diagrams

Develop characteristics and specifications for an electrical control circuit
· What do you want the circuit to do
· What components will be needed for the circuit
Design wiring diagrams to meet the required characteristics and specifications
· Identifying the relationship of controls and loads, in relationship to the power source
· Choosing between a "Ladder" and a "Pictorial" diagram
· Practice drawing and wiring (on paper) several simple and complex wiring diagrams
Develop skills in troubleshooting electrical circuits
· Seeing why using an ohm meter to "Ring It Out" is often a waste of time
· Understanding why the phrase "Where's The Volts" is so important
· Find failed components, wires, shorts, bad connections, etc. using a volt ~ amp meter, and a wiring diagram
Introduction to "Mr. Meter" (this is fun!)
· A whole bunch of troubleshooting exercises with class participation
· This is a proven and fun "stick with you" skills builder!
