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.

PSC 114.219 NoteException: 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.

PSC 114.219 NoteNote 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.

PSC 114.219 NoteNote 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.

PSC 114.230(1)(1) Application. [NESC 230A1 and 230A2, p. 90] (Omission) Rules 230A1and 230A2 of the NESC-2017 are omitted and not incorporated as part of the Wisconsin State Electrical Code, Volume 1.

PSC 114.230 HistoryHistory: CR 07-021: cr. Register January 2008 No. 625, eff. 2-1-08; CR 13-039: r. and recr. Register June 2014 No. 702, eff. 7-1-14; cr. PSC 114.230 (title) under s. 13.92 (4) (b) 2., Stats., renum. (1) and (2) from PSC 114.230A and 114.230I under s. 13.92 (4) (b) 1., Stats., Register March 2015 No. 711; CR 18-007: am. Register February 2020 No. 770, eff. 3-1-20.

1. Where there are curbs: supporting structures, support arms, anchor guys, or equipment attached thereto, up to 4.6 m (15 ft) above the road surface shall be located a sufficient distance behind the curb to avoid contact by ordinary vehicles using and located on the traveled way. For a redirectional curb, such distance shall be not less than 150 mm (6 in) from the street side of the curb.

21Where the US Army Corps of Engineers, or the state, or surrogate thereof has issued a crossing permit, the greater clearances of that permit or this code shall govern.

25Water areas not suitable for sailboating include portions of meandering rivers, streams and canals where the widest width does not exceed 50 m (165 feet) within any unobstructed,1.6-km (1-mile) long segment that includes the crossing or where the width does not exceed 50 m (165 feet) within the surface area of any segment less than 1.6-km (1-mile) long on the line-crossing side of an overwater obstruction. All rivers, streams, canals and creeks as defined by the Wisconsin department of natural resources (DNR) which meet this definition are considered not suitable for sailing.

PSC 114.232 NoteException: Regardless of width, the clearance over a canal, river, or stream normally used to provide access for sailboats to a larger body of water shall be the same as that required for water areas suitable for sailboating on the larger body of water. This also applies where a sailboat may be transported across such water with its mast extended.

PSC 114.232(1)(d)(d) Footnote 25 [NESC, Table 232-1, p. 102: metric; p. 106: feet] (Addition) Add the reference to Footnote 25 in the NESC-2017 Table 232-1 (both the metric and feet sections) on to the sailboating category titles of rows 6 and 7. It applies to all clearances in those rows.

PSC 114.232(1)(e)(e) Footnote 27 [Follows NESC, Table 232-1 Footnote 26, p. 102: metric; p. 106: feet] (Addition) Following Footnote 26 for Table 232-1 (for both the metric and feet sections), add Footnote 27 which reads as follows:

27A diagonal clearance equal to the required vertical clearance shall be maintained to uneven or sloping terrain within a horizontal distance of 3/4 (75%) of the required vertical clearance. All distances shall be measured from the conductors in their wind-displaced position as defined in NESC Rule 234A2.
