  1. Practice Code Look Up Smitty’s Speed Drills 2008 NEC Copyright 208 Ted "Smitty" Smith

  2. Directions • Left click on the presentation ICON located at the bottom of the slide directory to the left of the this slide. • Each slide will transition to the correct answer automatically in 2:00 minutes. The correct answer will transition in 5 seconds. • Do not worry about writing down the correct answer for now. You will have the opportunity to do that at the end of the two minute drill • Good luck • Some of the the slides will transistion faster than others as some timers are intentionally set to less than 2 minutes.
