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?
Fr
Answer: The Supplementary General Conditions specifies the job site requirements for
an
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
kl
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.
