For the same reason(s) you need to read the other prints - and not limit yourself to the electrical.

I know, sometimes it seems we are the only trade that even tries to look at the 'big picture.' Yet, we can't afford not to.

I have a picture thread going, where I had to rework some things, because I failed to pay adequate attention to the trim details.

We've all been surprised by that under-sink point-of-use water heater as well.

The NEC itself opened a whole can of worms, when they began to require certain door hardware on the doors of electrical rooms. (I have no idea even where to get such hardware!)

Now, looking at other codes ...

The ICC 'fire code' mandates the 'path of egress' have emergency lighting. This means some expensive fixtures on the OUTSIDE of the building.

The DOE 'energy calculator' (required here by the city) plays havoc with most lighting schedules.

The City here has gone 'tree crazy.' Something to keep in mind, as you make underground runs anywhere near parking lots.

NFPA 96, which covers kitchen cooking hoods, can play all manner of havoc with the HVAC, electrical, and alarm systems ... you really need to think this one through.

"LEED," as yet a vague, undefined code, is sure to much things up. If nothing else, look for a conflict with the 'egress lighting' requirement. "LEED," as I understand it, is a fancy way of saying 'green building.'

Thanks Bryan for the references. I will have to print this page to be sure I am aware of them all.

I think we all have the surprises and I am one of the engineers that come to the site only to be surprised by something that was slipped in or I missed! I don't like that, but it is good for me to be humbled (I wanted to put in my self talk but that would be to harsh, also, I am not balding - my head is just to fat for my hair).

Reno, your points are well taken.

I chuckled as I just recieved our 2008 NFPA 1194 update which conflicts with 2008 NFPA 70 (our dearly beloved NEC) on the placement of electrical pedestals. If you are accurate with your tape measure you can meet both codes.

LEED, though not code we are required to meet once we reach a certain size building, requirements in remote settings definately create conflict with the building codes on exits when I must have 0% uplight and I am required to calulate all aimable and unknown fixtures as 100% uplight.

It is also fun to meet 30% below ASHRAE 90.1 on lighting calculations due to presidential Executive Orders and still meet minimum lighting levels to be able to see to work.

I am just so thankful for IAEI and others like this site that help me keep a tentative handle on things.

And please don't forget the IBC/IRC structural codes, as we notch, bore and otherwise weaken structural members that the structural engineer would rather not be cut at all... In fact, we may want to politely remind our plumbing colleagues of the same, before they center-bore a structural 2x6 to fit 3" PVC pipe...

As for me, I have to not only contend with ICC and NEC, but a minefield of federal requirements and foreign codes. I don't care how experienced you are, it's impossible for one person to know them all. I run across new codes and requirements I'm bound to practically every time I crack a new reference. I'd say 99% of the time, we're in compliance even without knowing the requirement, just because it's good practice. (Also, it helps that the NEC is typically far more restrictive than any foreign codes.) But those handful of times, it can get to be a real pain in the ass...

Thanks for those references. I am continuing to develop a class for electricians that is called Beyond the NEC. Those code sections will be a big help. Some I had but others I don't think I did.

No problem guys.

I actually put this list together for an apprenticeship course, but eventually found myself given it to engineers, architects, and contrators. Make sure to cross-reference with the 2006 ICC codes. My sections were derived from the 2004 Florida Building Code which is based on the 2003 ICC codes. Some sections may have changed or been moved.

I have to think that one of the most frequently violated codes by Electricians is the often overlooked UBC. I have a lot of examples but I'll stick to just one since it is routinuely violated by almost everyone.

A customer in a commercial business wants a receptacle added so you fish it in for them. We all do this every day, no big deal right? The wall has double layer sheetrock so you need to use madison clips/battleships with the long tines. You install the receptacle, collect the money or get the billing form signed and go on your way. You did a good job right?

WRONG!, you just compromised a two hour fire wall and are in violation of the UBC. The UBC says that boxes in two hour walls must be "firmly" attached to a stud. Please note that you can still use cut-in boxes, but when you cut into the wall it must be against a stud and the box must then be screwed to the stud, and that only metallic boxes can be used.

Also, the UBC states that boxes in two hour walls must be at least 24" center to center. This applies to both sides of the wall in question. The reason for this rule is to ensure that there is only one penetration of one side of the wall in any stud space. Since studs are always either 16" or 24" on center, requireing boxes to be 24" apart ensures that no two boxes will be within the same stud compartment of the wall.

The last time you cut a box into a double layer wall did you fasten it to a stud? Did you look at the other side of the wall first to make sure there weren't any existing boxes within 24" of your cut-in location? Did you add your cut-in alongside an existing data/phone/power box that was within 24"?

We have all done this, I did it routinely until I became aware that I was violateing the UBC and my local fire prevention code. Since then I have noticed it as a violation and have to admit seeing it thousands of times.

Strip malls and commercial lease warehouse spaces are a great example. The individual tenent spaces are almost always seperated by two hour firewalls. How many times have you added cut-ins to those division walls without being aware that you were violating the code and opening yourself to liability?

Several years ago our IAEI lunch group had a guy from (USG?) who explained a lot about fire rated assemblies. I think everyone should see that show. The main lesson we took away is that squirting red caulk around a penetration does not make a fire wall whole again. These things are all assemblies that must be built or modified in the compliant way. There is a book and a web site that describes the various assemblies that comprise a penetration seal.
Bryan probably has more on this. He probably got the guy for us wink

Not just the electrical code, and in New Jersey we have a whole group of Rehap codes, on top of all the ones brian noted, our CEU's classes are busy every new cycle trying to keep up with all the changes, and not just the electrical codes.
