Thanks for all your replies but the speed limit comparison is simply not true . If that police officer doesn't know why,although he is not required to know why, that's his stupidity. Granted engineers made roads for maximum speed limits,but...during the energy crisis all hiways ,went to 55 mph. The government does that... Not engineers. The same hiways in parts of the USA are 85 mph. Again,puppets that you accept this for an answer. (Manufacturers) .like I said the people who wright the NEC and or fire people.whatever you want to call them. Perfect example is the NEC told the manufacturers that they now need to put cords on garbage disposers and dishwashers. I'm sorry but please... Don't ask me for one second to believe that the manufacturer tells the code people what to do.. remember this is the United States of America. The people ultimately vote and make the rules . Not money making manufacturers. Lobbyist lobbyist lobbyist that get paid to pay people In power legally or sometimes not. I'm just tired of stupid codes that make no sense. Stop and think. A lot of them are perfectly safe. And if they claim there not...it's the most rediclous reasoning that anyone should believe. Wow this is a long one.hey I'm an ass what can I say. Common sense is a thing that used to mean so much, seams no more . No such thing as common anymore. So people will now do illegal things because they know it won't pass code. Thinking they know how. Where as they could have done it legally because they could have afforded to pay.
