I agree with Tom. The installation will be per the latest Code, and probably justifiable in a courtroom, where most of don't want to be. The problem with such an installation will be with the AHJ. He has to enforce the former Code. The new installation by the newer Code may be viewed as a violation. And how do you argue your case to the AHJ? do you in fact take him to court? and on what premise? I am not familiar with NY or Chicago codes, but my guess is that they are more stringent than the NEC. The NEC gives us only a minimum safety for the use of electricity. It does not provide for the most efficient use of electricity, the one thing I wish it would include.
Thanks for your input. I also believe that the industry may want to train their people in the new code because they may have customers in other States that do adopt the NEC as soon as it becomes available.
Companies may want to use the latest code as a best practice to protect their buildings, equipment and staff.
1. I would think it prudent for any company to learn the 2002 regardless if the state doesnt use it. IMO it would be not be wise, to be nice, for them not to When you look at the many people who have input into the Code every year and cycle, I cant see how any state would have that many qualified people to input that kind of information. If a State does have its own code where did it come from, and who wrote it or was it copied from an NEC. Tom makes a very valid point, Liability, and I would think that anything less than the NEC would be nothing but trouble for the city or town.
Where I work in MD, (Baltimore Metro area) one jurisdiction is still using the '93 while the rest are using the 99 and soon the 02 Code.
I take the update classes so I will know what will be accepted in most areas. When I do work under the old Code I need to refresh myself on the old way of doing things. This is a pain on the changes that affect bathrooms and the like. I need to change my way of thinking.
I have worked in one county that will not accept a ufer ground. They say they don't have enough electrical inspectors and the building inspectors won't check for the wire on a footing inspection. It's not their job, it's electrical. How do you deal with 'logic' like that? Oh well, at least they use a Code.
