    • 14: Size of the wire, -3: # of current carrying conductors. Round White cable used for general lighting and general purpose Receptacles. Used
    • mostly in residential applications. 15A max.
  14. 12-2 AWG
    12: Size of the wire, -2: # of current carrying conductors. Flat Yellow cable used for Receptacle circuits and appliances. 20A max
  15. 12-3 AWG
    12: Size of the wire, -3: # of current carrying conductors.Round yellow cable used for Receptacles circuits and appliance. 20A max
  16. Continuous Load
    A continuous load is a load where the maximum current is expected to continue for three hours or more..
  17. Induction heating
    • the heating of a conducting material as a result of the electric
    • currents induced in it by an externally applied alternating magnetic
    • field
  18. What is the minimum amperage required for a main residential panel.
    100A
  19. What is the power delivered from the utility companies.
    120/240 volts single phase.
  20. Short circuits
    • A low-resistance connection established by accident or intention between
    • two points in an electric circuit. The current tends to flow through
    • the area of low resistance, bypassing the rest of the circuit either phase to phase or phase to neutral.
  21. Ground Faults
    The momentary, usually accidental, grounding of a conducting wire. Usually ground to any current carry conductor.
  22. What are the temperature rating of the wires for underground, indoors, and outdoors.
    • 60 deg C or 140 deg F -Underground
    • 75 deg C or 167 def F- Indoors
    • 90 deg C 0r 195 deg F - Outdoors
  23. AFCI
    Arc Fault Circuit Interrupter (Residential)
  24. OCPD
    Over Current Protection Device
  25. AHJ

  26. Underwriters Laboratory. Anything with this label has been strenuously tested in a lab and passed.
  27. EMT
    Electric Metallic Tubing
  28. NEMA
    National Electrical Manufacturing Association
  29. Objectionable Current
    • "objectionable current" is any current flow over conductors not designed
    • to NORMALLY be current carrying.  One cause can be from improper bonding pass the Main as in having your grounded across your grounding wire.
