Actually, Colorado adopted on July 1, 2005.
Understand you are going to have to use the all of the rules applied to electrical construction in my state.
Dave, the test is based on the NEC. They do not focus on any local amendments (are there any at the state level?), because you don't have access to them when you take the test.
Moving on...
By the time you get to the last receptacle in the Entertainment Room, you have gone through 4000 feet of 14-2 romex. Mr. Homeowner moves into his new home, and his first night he turns on his $15,000 65" Plasma HDTV. Poof. The TV is somehow affected by the voltage drop and fries all the internal circuitry.
What killed the TV? Was it the 400 receptacles or the 4000' of voltage drop due to a poorly designed system? Who died as a result? Did the structure survive? Will the free-market system not take care of this problem?
The EC will buy a new TV, or will correct the system, or will go to court, or skip the country. Stuff happens every day. Voltage drop happens every day, and the code is nearly silent on it.
They (inspectors) are going to use reasonable expectations for a good installation.
But that leaves the realm of safety and becomes design. 90.1(A), (B) and (C) are screaming it from the rooftops. It is not a design manual. Whenever it delves into designing, as it does in 210.52, it becomes a fiasco. Something that seems so clear to CMP-2 results in
heated, month-long debates around here.
When you chase the devil out of the forest, you'd best be prepared for the winds on the plain. Once real
written rules are left behind, then anarchy is the result.
What happens when the inspector's version of common sense is no more than two receptacles per circuit? Or if you're all done, and the guy says, "I'd like to see that xxxx on it's own circuit" despite your own careful thought and planning and signature on the design?
There are plenty of good inspectors in this state, there's no reason to coddle the bad ones. Bad ones enforce questionable principles not directly related to safety. If there is a clear danger evident that the code does not address, then a good inspector will step forward. But when it comes down to failing for if's and maybe's and could-happen's, it is generally a textbook case of somebody in the wrong position, IMO.
Happy Easter, Dave. Don't let this stuff mess up your weekend!
