Review .......................................................................................................................................................... 1
Note to instructor: It is recommended that students be required to respond, where appropriate, with
answers that are complete sentences.
REVIEW
Refer to the National Electrical Code or the working drawings when necessary. Where applicable,
responses should be written in complete sentences.
1. What section of a commercial building’s specification contains a list of contract documents?
Answer: A list of the contract documents is contained in General Clauses and Conditions. A
listing of the Commercial Building contract documents is presented in this chapter under the
heading ―Commercial Building Plans.‖ The instructor may wish to have the students check over
this listing and compare it with the plans provided.
2. The requirement for temporary light and power at the job site will be found in what portion of a
commercial building’s specification?
Answer: The Supplementary General Conditions specifies the job site requirements for
temporary light and power. In some contracts, this electrical system becomes the responsibility of
the general contractor; in other contracts, it is the electrical contractor’s responsibility to install
and maintain the temporary electrical system. The instructor may wish to refer the student to NEC
Article 590 and discuss the requirements in detail.
3. The electrician uses the Schedule of Working Drawings for what purpose? Answer: The
electrician uses the Schedule of Working Drawings to determine whether all of the drawings are
at hand. The information on ―the other sheets‖ may be very important, especially in coordinating
with other contractors.

26. Luminaire style F is four feet long. The length in SI units, as specified by the NEC, is
Answer: The length in SI units is 1.22 m; 4 ft × 0.3048 m/ft = 1.2192 m. As will be discussed
later, this luminaire is now called a 4 by 2 or the equivalent 1200 by 600 in metric terms. This
question assumes that the luminaire is exactly 4 ft long.
