Let's see if this workbook is for you. Here's a ten question quiz. Get out your code book and calculator for these.

1.  What is the expected current draw for a 4500 watt 240 volt water heater?

2.  What is the total resistance for 6 resistive loads that are 30 ohms each if connected in parallel to the source?

3.  What size rigid PVC raceway Schedule 80 is needed if it contains 2 #4/0 THW, 1 #1/0 THW and 1 #3 THW copper conductors?

4.  What is the minimum even numbered square dimension for a pull box which contains a total of 20 #12's, 20 #10's, and 20 #8's. All terminate in splices in the box. The box is 4 inches deep.

5.  What is the initial standard maximum overcurrent protective device permitted for a 5HP 240 volt single phase motor if a non renewable fuse is planned for the installation?

6.  What is the minimum square dimension for a pull box where 6 #1 THW conductors are U pulled through a box. Note that the conductors enter and leave the box in 3" PVC Schedule 80 raceways. The raceways are each 3" from the corner of the box. Both raceways are on the same wall of the box, hence it is called a U pull. The box is 6" deep.

7.  What is the service feeder demand for 26  14kW single phase household ranges in a multi family dwelling if powered by a three phase service feeder?

8.  What is the net lighting and appliance feeder demand for a 3600 square foot residential dwelling which has four small appliance branch circuits and one laundry circuit if the standard service calculation method is used?

9.  What is the expected output voltage of a single phase transformer that has an input voltage of 240 volts, an input current of 8 amps and an output current of 72 amps when it is 90% efficient?

10.  What is the expected run voltage at load for a 32 amp resistance heater load which is located 320 feet from the 120 volt source if #3 THW copper was used for the circuit?

If you miss the correct answer on even one of these questions, then the Electrician Calculations Workbook would be a useful tool to add to your study library. Why not Invest In Yourself? Brain tools pay big dividends. See the bottom of this page for a link to the answers.
