Transcript 2011 Changes Two Minute Drill - E Light Safety, Training

INSTRUCTIONS
 Click on the slide show ICON in the lower left hand corner of this screen to start the slide
show. The timer will only work if you put the presentation into
Presentation Mode.
 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 2014 NEC.
