Electric Motors Calculations Workbook
Most electricians think the branch circuit conductor, disconnect, and
overcurrent protective device are sized based on the nameplate flc of the motor.
If this is you, then this workbook might be just what you need to get motor
calculations straight. These calculations are to be calculated based on the NEC
table values. Only motor overloads are based on nameplate, with a few
exceptions. Aren't there always a few exceptions.
This 144 page workbook contains over 5000 different motor calculations and
motor related questions. Answers are provided for each question. Audio support
is also available online for every question type. Plus there are hyperlinks to
more problems if you need them to get proficient.
$24.99 plus $4.60 postage to any USA address.

Take a look at Check
Values where you can use specific values to verify that you are entering
data correctly into a formula with your calculator.
Also new is Tables
where you can find tables not in the NEC but probably should be there.
Use the navigation bars at the top of this page to go to the mathematics
calculation topic you want to access. Please note that many links are provided

A Texas Instruments TI-30Xa calculator for about $12 is the correct
calculator for all calculations on these web pages. No fancy calculator is
needed. The TI-30Xa is perfect for every electrical calculation an electrician
needs to make. Don't get any other version, though. The TI-30Xa has all the
necessary keys for functions which are needed by electricians. If you have some
other calculator, save it for your income taxes. Pry open your wallet, take out
twelve bucks, and buy a TI-30Xa. Instructions are provided based on the TI-30Xa. No, I
do not own stock in the Texas Instruments Corporation. And I have received no
compensation for this promotion. It just happens to be the best calculator for
what an electrician needs a calculator to do.

An excellent glossary for electricians is included HERE.
