Most state and local authorities require that utility construction comply with either the ANSI/NFPA 70-1999, NEC®, and ANSI/IEEE C2-1997, NESC, or some earlier editions of the ANSI/NFPA 70, NEC®, and ANSI/IEEE C2, NESC. Some authorities have their own more stringent codes which may or may not be embellishments of the ANSI/NFPA 70, NEC®, and ANSI/IEEE C2, NESC.(d) RUS borrowers shall make certain that all construction financed with RUS loan funds comply with: (1) The provisions of this section and §§ 1755.504 through 1755.510 and the ANSI/NFPA 70-1999, NEC®, and ANSI/IEEE C2-1997, NESC codes, or any more stringent local codes; or(2) The provisions of this section and §§ 1755.504 through 1755.510 with borrower added adjustments to bring construction into compliance with any more stringent local codes.(e) This section and §§ 1755.504 through 1755.510 are intended primarily for the installer who will perform the work. It assumes that decisions regarding the selection of grounding electrodes, locations, and types of equipment have been made by the RUS borrower or the engineer delegated by the RUS borrower.(f) Only a qualified installer as defined in § 1755.501 shall be assigned to make installations without advance planning and without direct supervision.(g) This section and §§ 1755.504 through 1755.509 contain information which is normally not provided on the construction drawings which are included in § 1755.510 .(h) All work shall be conducted in a careful and professional manner. Service wire and cable shall not be trampled on, run over by vehicles, pulled over or around abrasive objects or otherwise subjected to abuse.(i) When situations not covered by this section and §§ 1755.504 through 1755.510 arise, the RUS borrower or the engineer delegated by the borrower, shall specify the installation procedure to be used. The requirements of paragraph (j) of this section shall be complied with in every installation.(j) NIDs, BETs, and fused primary station protectors shall be installed and grounded to meet the requirements of the ANSI/NFPA 70-1999, NEC®, or local laws or ordinances, whichever are more stringent.(k) Battery polarity and conductor identification shall be maintained throughout the system as indicated on construction drawings 815 and 815-1 contained in § 1755.510 . Color codes and other means of conductor identification of buried and aerial service wires shall conform to the requirements of this section and §§ 1755.504 through 1755.510 .(l) All materials for which RUS makes acceptance determinations, such as service wires and cables, ground rods, ground rod clamps, etc., used in service entrance installations shall be RUS accepted or RUS technically accepted. Borrowers shall require contractors to obtain the borrower's approval before RUS technically accepted materials are to be used in service entrance installations. Borrower's shall also ensure that the cost of the RUS technically accepted materials are at least 6 percent less than the cost of equivalent RUS accepted materials, as specified in "Buy American" Requirement of the Rural Electrification Act of 1938, as amended (7 U.S.C. 903 note). Materials used in service entrance installations which are of the type which RUS does not make acceptance determinations shall be of a suitable quality for their intended application as determined by the RUS borrower or the engineer delegated by the RUS borrower.(m) On completion of an installation, borrowers shall require the installer to make all applicable tests required by §§ 1755.400 through 1755.407 , RUS standard for acceptance tests and measurements of telecommunications plant. 66 FR 43317 , Aug. 17, 2001, as amended at 69 FR 18803 , Apr. 9, 2004
