Thanks Joe.....
I think if the "spirit" of the code is always considered in regard to the "letter" of the code, we will have been successful in our teaching and application.
I have always seemed to learn better when the concept is presented along with the doctrine, hence a "common sense" is formed.
I have not had the privlege to sit in one of your classes but I have read many of your explanations over the years and I must say you are among the best when it comes to teaching the NEC. No "suck-up" intended, just stating the facts.
Thanks,
Dave
