Open supply lines shall not be run over wells. A horizontal clearance with conductors at rest of no less than 3/4 of the vertical clearance of the conductors to ground required by Rule 232, and a horizontal clearance of not less than 3.0 m (10 ft) with conductors displaced by wind according to Rule 234A2, shall be maintained between open supply conductors and wells. Persons installing such wells shall also comply with this requirement.

PSC 114.234 NoteException: This rule does not apply to Groundwater Monitoring Wells defined in Wis. Admin. Code ch. NR 141 provided such wells are installed using hydraulic push methods, such as a Geoprobe type rig (The vertical clearance required for a Geoprobe is typically less than 10 feet.) and where sampling is accomplished using a bailer or a submersible pump attached to flexible tubing. This exception is not intended to apply to monitoring wells installed with drilling rigs that are taller than 14 feet or sampling methods that require sections of piping (steel or plastic pipe).

PSC 114.234(8)(8) Swimming pools. [NESC 234E1, p. 130] (Addition) Add the following sentence to the beginning of paragraph E1:

Pools and appurtenances shall not be placed under or near existing service-drop conductors or any other overhead wiring; nor shall such wiring be installed over a swimming pool or the surrounding area unless such installation complies with the clearances or the exceptions specified in NESC Rule 234E1.

PSC 114.234(9)(9) Grain bins loaded by permanently installed augers, conveyers, or elevator systems. [Follows NESC 234F1, p. 131] (Addition) Following 234F1, add exception and note to read:

PSC 114.234 NoteException: Farm silos that are loaded by a blower through a vertical metal tube permanently attached to the side of the structure are not considered grain bins.

PSC 114.234 NoteNote 2: Typical cylindrical farm silos are considered buildings for the purposes of this code and the clearance requirements of NESC Rule 234C, as amended herein, would apply.
