There is hereby adopted by the village for the purpose of establishing rules and regulations for the construction, alteration, removal, demolition, equipment, use and occupancy, location and maintenance of the buildings and structures, including permits and penalties, an electrical code known as the National Electrical Code, being particularly the 2020 edition, with all subsequent amendments, of which not less than one copy has been and now are filed in the Office of the Village Clerk. The code is adopted and incorporated as fully as if set out at length herein. From the date on which this section shall take effect, the provisions thereof shall be controlling the construction of all buildings and other structures therein contained within the corporate limits of the Village of Romeoville. Additions, amendments, and deletions: The following sections are hereby revised as follows.
(A) Article 90.7 Examination of Equipment for Safety: For specific items of equipment and materials referred to in this Code, examinations for safety made under standard conditions provide a basis for approval where the record is made generally available through promulgation by organizations properly equipped and qualified for experimental testing, inspections of the run of goods at factories, and service-value determination through field inspections. This avoids the necessity for repetition of examinations by different examiners, frequently with inadequate facilities for such work, and the confusion that would result from conflicting reports on the suitability of devices and materials examined for a given purpose.
It is the intent of this Code that factory-installed internal wiring or the construction of equipment need not be inspected at the time of installation of the equipment, except to detect alterations or damage, if the equipment has been listed by a qualified electrical testing laboratory that is recognized as having the facilities described in the preceding paragraph and that requires suitability for installation in accordance with this Code.
(1) Article 90.7A The NEC, along with OSHA and the U.S. Department of Labor, require all industrial machines and equipment to be tested and listed by NRTL.
Machines that are custom made or made by a manufacturer that no longer exists or that are constructed on site for a specific use may be inspected by a third party "Licensed Electrical Engineer" to determine that it is safe for use. This engineer may provide a letter to the Municipal Building Department, or AHJ, with his/her stamp on it, stating that he/she inspected the machine for electrical safety and has determined that it is safe to operate. This is an acceptable method of field certification. This letter is to be kept on file on site and at the municipality/AHJ office.
