PHILIPPINE ELECTRICAL CODE REVIEWER

I dedicate the accomplishment of this work to God, who has given me strength and enough wisdom to accomplish such task of summarizing and reviewing topics covered by PEC 2009. I also dedicate this work to my beloved mother, Darlene Dumbrique, the girl who has been there for me even through the hardest of times. And because of my love for her I put my best in every work I have to give in return to her love.

I dedicate this work as well to my family, relatives, friends, to all of the people who have helped me in financial provisions especially when I am still studying, to all who believed in me, motivated me, inspired me. Thank you. And this work is also for all the people that would read this that they may be blessed and be helped by this piece of work I have done during my review for Board Exam (September 2014) for them to gain knowledge and understanding. God bless!
