Electrician Job Question:

The NEC is a model electrical code devised and published by the
National Fire Protection Association, an insurance industry group.
It's revised every three years. The 1993 version has been released.
You can buy a copy at a decent bookstore, or by calling them directly
at 800-344-3555. The code exists in several versions. There's the
full text, which is fairly incomprehensible. There's an abridged
edition, which has only the sections likely to apply to most houses.
And there's the NEC Handbook, which contains the ``authorized
commentary'' on the code, as well as the full text. That's the
recommended version. Unfortunately, there's no handbook for
the abridged edition. And the full handbook is expensive --
US$65 plus shipping and handling.
