       Tom Henry's "Perfect - Practice - Pass " Modules

                The perfect private tutor designed for you by Tom Henry.

    

 


                                 

                                     THE QUAD 4 Modules



    These modules are for a person taking their first electrical exam and for the electrician that didn’t pass exam by just a very few points. When working calculations one must attack their weakness in order to pass an exam.
    Over the years I have tutored students one on one to strengthen their weakness. I have written these modules so you can tutor yourself on your weakness with perfect practice. Proven learning methods. The perfect private tutor designed for you by Tom Henry.
    Practice doesn’t make perfect. Perfect Practice makes Perfect! What “perfect” practice really means, mistakes aren’t the problem. The problem is not taking the time to articulate the specifics of the mistake, the cause of the mistake, and the potential solutions, so you can avoid making that same mistake over and over. These modules will fully check you on this!

Study Smarter     

   You could say that the phrase study smarter is similar to the phrase study efficiently. The more effective you are in studying, more will get done and less time is wasted. Before you can go about changing this and becoming a more efficient student you need to be aware of your current effectiveness. Find your weakness, this has to be measured before we can improve it, the reason is fairly obvious. If you do not know where you stand, how will you know how far you’ve gone?
    

Tips for “Perfect - Practice - Pass”
    

    The key is reading the question looking for the key words, feeder-service, branch circuit, neutral, equal sizes, unequal sizes, school kitchen, school classroom, single-phase on three-phase.
    If an appliance will fit in more than one column, always compare the columns and select the smallest kW demand.    
    

                                                                            

       Get started today with “Perfect - Practice - Pass”

 

                              
        The National Electrical Code Table 220.55
  Household Cooking Equipment Demand Factors   

  A troublesome area for the electrician working maintenance or in the oil   fields.

    Now comes the key word “HOUSEHOLD” an area many electricians    have not worked in.

Item #992 Cooking Equipment Demand Factors.....................$16.00

   I can always relate to the lady that was a secretary for an electrical    contractor and had never connected an electrical wire. She attended  my prep class for Journeyman license and scored 77% first try, Two  years later I begged her to attend class and take the Master exam, in    which she scored 76% first try.
    Back in 1984 there was a county in Florida where you could take the  exam without showing any work in the field.
    She proved my point, you weren’t tested on how to connect a wire,    you are tested on how well you can read a question and SEE the key    words and operate a calculator!

Item #993 Dwelling Calculations.....................$16.00

   "OTHER THAN A DWELLING" Learn the correct way to size the service demand to a bank, restaurant, school, office, motel, hospital, farm, etc. Apply all the demand factors from the Code Tables.
Section 220.40 states: The calculated load of a feeder or service shall not be less than the sum of the loads on the branch circuits supplied, as determined in Part II of Articel 220.
    It is not permissible to assume any demand factor that would result in a calculated load that is less than the Code-prescribed minimum from Table 220.12. Providing capacity for less than the Code-prescribed minimum represents poor design and is a violation of the NEC.


Item #995 Commercial Calculations.....................$16.00

   Boxes shall be of sufficient size to provide free space for all enclosed conductors. In no case shall the volume of the box be less than the fill calculation. Providing capacity for less than the Code-prescribed minimum represents poor design and is a violation of the NEC. This Module will show how to calculate the maximum number of wires the Code allows in a box or conduit.Limiting the number of wires and circuits in a single enclosure will minimize the effects from a short-circuit or ground fault in one circuit.

Item #997 Box and Conduit Fill Calculations.....................$16.00

  Item #998 THE QUAD  ALL 4 Modules.....................$60.00
