[Follows NESC 218, p. 84] (Addition) Following NESC 218, add section 219 to read:

219. Marking of poles and structures carrying high voltage supply lines.

A. Every corporation, company or person constructing, operating or maintaining an electric transmission line with a voltage of 2,000 or more between conductors and the ground shall place warning signs from 1.2 to 2.45 m (4 to 8 ft) above the ground upon all poles or other structures supporting the line.

Exception: Existing poles and structures which were required to be signed by s. 196.67, stats. and were installed prior to January 1, 1995, are permitted to comply with the warning sign requirements which existed on December 31, 1994.

B. Warning signs installed as replacements or new facilities on overhead electrical supply line poles and structures shall comply with the following standards:

1. Warning signs which meet the requirements as to format and color of American National Standards Institute standard ANSI Z535.2-2011 for safety signs.

2. The overall dimensions of these signs shall not be less than 25.4 cm by 17.78 cm (10 in by 7 in) except that in those situations where use of a sign this size is not practical, two or more signs not smaller than 17.78 cm by 12.7 cm (7 in by 5 in) may be substituted.

Exception: Existing poles and structures installed prior to July 1, 2003, are permitted to continue to use the “Danger - High Voltage” sign format meeting the requirements of the prior rule until such signs are replaced.

Note 2: This rule amends and expands the application of the warning sign requirements of s. 196.67, stats., as it existed prior to its revision which became effective on January 1, 1995. In 1993, this statute was revised by deleting the specified location provisions limiting the required signing to certain poles. As a result, all poles and structures supporting lines with a voltage of 2,000 or more installed after the effective date of January 1, 1995, are required to carry warning signs. See s. 196.67, stats.

Section 23. Clearances

Note 2: The specification of clearances in Rules 232, 233, and 234, first adopted in the NESC-1990, and continued in the 1997 edition of the NESC adopted herein, have been revised in both concept and content to reflect the new Uniform System of Clearances approach which is described in Appendix A of NESC-1990, NESC-1993, NESC-1997, NESC-2002, NESC-2007, NESC-2012 and NESC-2017. Because the approach and the application of the rules have been revised, it must be understood that clearance values of editions of the national and state codes prior to 1990 cannot be directly compared to those of editions of the codes after 1990. See Appendix A of NESC-1990, NESC-1993, NESC-1997, NESC-2002, NESC-2007, NESC-2012, or NESC-2017.
