(1) TABLE PSC
					 114.232 -1. [NESC, table 232-1, pp. 99- 102: metric; pp. 103-106: feet]
(a) Footnote 18 [NESC, Table 232-1, p. 101:
					 metric; p. 105 feet] Change Footnote 18 to read as follows:
18For uncontrolled water flow
						areas, the surface area and clearances shall be based on the ordinary high
						water mark.
(b) Footnote 21
					 [NESC, Table 232-1, p. 102 metric; p. 106: feet] Change Footnote 21 to read as
					 follows:
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.
(c) Footnote 25 [NESC, Table 232-1, p. 102:
					 metric; p. 106: feet] (Change) Change Footnote 25 to read as follows:
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.
Exception: 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.
(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.
(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.
(f) Footnote 27 [Follows NESC, Table 232-1
					 Footnote 26, p. 102: metric; p. 106: feet] (Addition) Add the reference to
					 Footnote 27 in the Table 232-1 (both the metric and feet sections) to the
					 conductor category titles of columns 3, 4 and 5. It applies to all clearances
					 in those columns.
