Instructions
 Click on the slide show ICON in the lower left hand corner of this
screen to start the slide show.
 A question will appear and stay on the screen for 2 minutes. The
question will then be replaced with the correct answer and code
reference. This process will repeat until you reach a slide with a stop
sign.You can then click on the slides and the questions and answers will
be repeated without the timer so you can look up the answers or take
notes.
 Do not worry about writing down the answers until after the timed
portion of the program.
 Concentrate on finding the answer and improving your speed using the
NEC. This drill is focused on changes to the 2008 NEC.
