Electrical Grounding:

• The importance please read carefully(for your sake)
• Sizing and purposes How big and why.
  
• Grounding: Moble Homes and other subpanels.
• Gfi - Gfci These protect you and yours.

Very dangerous electrical connections

• Panels and Subpanels What is the difference?
• Multi-wire circuits Two circuits one neutral
• Loose Neutrals?Why is the voltage too high on some receptacles and too low on others? Why are some lights too bright and others too dim?

Common Electrical Connections:

• 3-way Switches
• 4-way switches
• Motor Start-Stop Station
• Hand Off Auto Hand off Auto is a switch with maintained contacts Auto-Off-Jog is same hookup with spring return to off from Jog position and maintained contact to auto position.

  Electrical Basics:

  • The Atom This is where electricity originates.
  • Voltage This is part of what electricity is.
  • Ohms laws These are some of the laws by which electricity works.
  • Current This is the strength of electricity.
  • Resistance This is the opposition to electricity.
  • Magnetism This is a part of nature that electricity uses to its advantage.
  • Capacitors These electrical components have the ability to store electricity, and release it later.
  • DiodesElectricity's check valve that converts ac to pulsating dc voltage.
  • TransistorsAn electronic current control device.

  Transformers:

  These transform electricity from one amount and strength to another.
  • Inductors These components induce votage and current in it's neighbors.
  • Mutual InductanceSame to you neighbor.
  • Transformer ActionsHow transformers work and why.
  • PowerHow much electricity can we transform from the primary to the secondary.
  • Phase "what is a phase"
  • Step-up Step-down TransformersVoltage higher or lower and Current stronger or weaker.
  • AutotransformersA type of transformer.

  Motors and Generators:

  Make and apply electrical energy.

• GeneratorsCause electricity and make it move.
• Single-Phase MotorsA type of motor.
• Three-Phase MotorsAnother type of motor.
• Shaded Pole MotorsStill another type.
• Split-Phase MotorsHere's another.
• Compound Wound MotorsAnd another.
• AC Generators:More generators.
• Alternators/generators:Alternate/generate?
• DC Generators Direct current generators.
• DC MotorsDirect current motors.
• Series DCA type of direct current motor.
• Shunt DCAnother type of DC motor.

Electrical Wiring:

What wiring consists of and how to do it.
• Electrical ServicesThe part that connects the building to the electrical service provider.
• Electrical CircuitsThe part that provides electricity to your electrical items.
• Sizes and Types of wireWhat kind and how big.
• Wiring HintsWarnings, advice, etc.
• Hazardous ( Classified ) Locations.
