I was a state Electrical inspector from 1988 to 1996. Since 1996 I have
returned to the tools and work as a construction electrician. I have been
reading some of the intellectual writings put online about application of
the NEC rules. I have to say, there are entirely too many people teaching
and writing about the NEC that have no idea of what goes on in the field, or
else they are ignoring the facts. I think too many of them have been away
from the tools so long that they live in an ivory tower far removed from the
real world.
In the real world we bend the rules, modify the rules, and cheat to make it
work and to make a profit while attempting to make a safe installation. So
often we design our own installation to use the available materials rather
than buy the materials to meet the engineer's design - if there ever was
one. Anyway, that is the way I see it these days.
I still maintain and run electrician.com and attempt to provide continuing
education and online calculators for practical electricians. But everyday I
cringe at what I discover and learn in the field, and am baffled how I am
willing to modify a code rule and find a defense for it to save a few hours
work. And I think I am a lot like many others out there doing electrical
work.
Does this make me a bad electrician? Maybe yes, and maybe no. It does make
me an employable electrician - if you get my drift!
Sure bend the rules. Can you sleep at night knowing that your shoddy work
killed a
family?

What are your credentials to make this statement?
Many, many code rules are based on theory rather than actual practice. Some
code rules are instituted at the behest of an industry trying to enhance the
bottom line.
I often see new code rules that I would love to see the substantian for.
Empiricle data that is used to victimize all users of the NEC may actually
only apply to a particular industry.
are you saying that there are so many codes and rules, some even
conflicting, that its possible to find discrepancies in even the most
expert, professional installation?
i recall the time i had a city inspector (with a badge and a gun) tell me my
extention cord was the wrong color (orange)

Or the rules may be more intended to deal with the lowest common denominator
in electricians, and where applicable, DIY homeowners. And maybe those
teaching efforts are as well.

Lots, maybe even most, electricians can do that properly. Some would not
be able to figure it our correctly. I read about the retired electrician
who installed new grounded outlets with no ground wire for a friend, and
tied the grounds to neutral. At least he's retired.

That was an interesting voltage drop calculator. I ran it on some extreme
values, where the voltage drop should have been half or more of the supply
voltage, and it gave me negative voltage drop instead (as it were trying to
tell me that thin wire run too long would create power). Maybe that's what
has the "free power" kooks going :-)
I have on my projects plate to build a new voltage drop calculator that will
not only get the right voltage drop, but also draw pretty graphs that can
show the drop over either changing distance, changing wire size, or changing
loads. Unfortunately, the calculations are not that simple, especially
considering mixed linear, reactive, and harmonic loads ... and loads that
change due to the effect of the voltage drop itself.

In my view that does not make you a bad electrician. But I would not want
a bad electrician trying to do some of what you describe. Maybe more theory
is required in the education process?
I'm not an electrician and do not plan to be. My career field is networks
and programming. One problem I have seen in my own field is that new tools
and methods intended to make programming easier and more reliable for good
programmers have also had the effect of enabling bad programmers to be able
to accomplish something where without those tools they would fail miserably.
As good as these tools are, they cannot overcome a bad programmer, and in
my experience, these are causing more bad programmers to enter the field.
For example, virtually every year 2000 bug I found on or after 1 Jan 2000
was written in a language like this, or otherwise used some tools. In my
opinion, entry into the field needs to be restricted by some people to those
who are smart enough to not do the mistakes in applying their efforts the
wrong way.
I'm not sure how that can be applied to electricians. Maybe what is needed
is to split the NEC into code specific to certain levels of qualifications
(with the bottom rung being the residential DIY-er).

Bending the rules does not necessarily mean shoddy work. The rules might
have to be bent just to make things safer than normal. Much of what NEC
specifies isn't specifically for safety of that work, per se, but to be
sure that the next person to come along, we'll call him "the least common
denominator", won't be confused and do it all wrong. An example is the
requirement for wire color. You can wire up new circuits with all the
wrong colors, and the electricity won't know a thing about it; it will be
just as safe (assuming you did it right). Subsequent electricians who
are at least aware that the colors are wrong (this would be thec ase if
there were no rules or standards for color) could deal well with it if
they are smart enough. Trouble is, there are today too many that are not.
Now I would not suggest using the wrong colors, and in fact it is allowed
in certain cases to remark wires to another color (to handle material
availability issues, I presume).
"I'm not sure how that can be applied to electricians. Maybe what is needed

So I can call myself a DIY-er and get away with murder?!? Good call. Where do
I sign
up?

That's quite a stretch of logic!
No one said anything about murder ... until you did.
Clue: The code for the DIY would be more strict and specific as to how
to do things. The code for top level electricians would give them more
leeway in figuring out how to do unusual situations safely.
The NEC is a great example of the concept that IQs add recipocially.
Take a code comitte with an average IQ of 130 and they produce a
section that reads like it was written by a grade school dropout.
You can read a lot of sections of the NEC and not know what the hell
they were talking about.
I think I read in EC&M a few years ago that the purpose of the NEC
was not to prevent fires or save lives but to generate funds for the
NFPA. It's their biggest cash cow and it provides the payroll and
funds for a lot of other activities as the NFPA. It also supports a
lot of people who run seminars and classed on lwhat the NEC says.
How many other books do you buy that require you to buy another book
to tell you what the first book said? First the NFPA sells you a
codebook and then they sell you a handbook to tell you what the code
book says. More dollars to the NFPA.
Ever wonder what the cost of a poorly written code is? Think about
all the research, debates, red tags ( unintentional things because
someone misunderstood the code) that waste time and cost money.
I don't think you can say your bending the code, because a lot of
times you can't tell what it was in the first place.
And has any one told the NFPA that one picture is worth a thousand
words??
You can't blame it all on NFPA. There are some building officials who get so
hung up on little bullshit that they miss the overall intent.
Swimming pool ladder sockets is one I am fighting about right now. Permacast
(the major manufacturer) has a superior design for the grounding but the old
farts are tagging them because a #8 is "under a screw". This is is in two
molded grooves and far superior to a separate lug under one screw that will get
twisted loose before the concrete hits it but there is no talking to these
guys. They are demanding a proof of U/L approval and Permacast says this is not
enough of their product line to spend that much effort on. The guy I talked to
wasn't even sure they made them.
I still have an open challenge to any inspector or building official. Put on
your lug, hook up a #8 solid and clamp the other end. Now twist that socket
around like you are a concrete guy trying to position it and see how easy it is
to loosen the lug.
Then try the "wire under the screw" laying the #8 in the groove, tighten the
screw and just try to break it loose, try anything. There are actually 2
grooves (one on each side) so you can fold the wire back and get two
connections
You will break the #8 before it comes loose, even with one.
"Thinking" does not seem to be in the job description of BOs and I though that
was why we had 90-4.
BTW in my pool I used the molded "lug" in the cup, not a separate lug. It
looked like the safest way to go for me and my family.
I think you missed Phil's point.
The premise is that an experienced electrician or engineer should be
allowed MORE latitude than a DIYer.
A DIY should be required to follow code to the letter since they have
little basis to judge exceptions.
My belief is that a properly written code should be followed at all
times. There could be more exceptions (X is permitted under proper
supervision...) that would allow for the practical side of the world.
Just how much danger will 405 degrees of bend in the conduit run
between boxes cause ? More than an extra box in an inconvenient
location?
