Grounding Unless otherwise performing work with live line or other approved insulated tools, Overhead, Underground or Station conductors and equipment normally operated at a voltage in excess of 600 Volts shall not be worked on until de-energized and the normally energized parts have been tested as de-energized with an approved device for indication of voltage and all conductors have been short circuited and grounded according to business unit procedures. Backfeed from transformers, energized high voltage conductors which cross over a de-energized conductor and unprotected energized conductors which cross under a de-energized conductor shall be considered possible sources of supply. This shall not preclude the removal of grounds for test purposes. When the work on such de-energized conductors involves the wiping or testing of insulators only, high voltage conductors crossing under such de-energized conductors need not be considered a possible source of supply. Only approved grounding and jumper equipment shall be used. This equipment shall only be used for grounding purposes. Portable grounding devices shall be secured to permanently grounded objects at the location selected for grounding in the following order of priority: Station ground 4-wire multi-grounded primary neutral Steel structures Anchor rods If none of the foregoing are available, an approved temporary ground rod shall be used. An approved testing device shall be used to prove conductors or equipment is de-energized before grounding. The conductors or equipment shall be grounded and short circuited with approved grounding devices. Grounding devices shall be applied and removed with live line tools. When the primary neutral conductor is used as the grounding medium, grounding devices must be connected to an additional approved ground. NOTE A multi-grounded primary neutral, as opposed to a "neutral of 4 kV isolated neutral system" is defined as a neutral conductor on a primary circuit, that has grounds attached to it, at intervals of up to 1,200 feet. If a multi-grounded primary neutral has grounds attached to it at intervals greater than 1,200 feet, it should be reported, however it shall still be considered a priority for grounding purposes, over steel structures, anchor rods, and driven grounds. The grounding devices shall first be connected to a ground before being brought in contact with any conductor to be grounded. When being removed, they shall be removed from all conductors before being disconnected from ground. No employee shall handle any conductive portion of the grounding device while it is being installed or removed from the conductors, except when using live line tools. The employee applying the grounding device shall determine that all persons are a safe distance from any portion of the grounding device before contacting the conductor with the grounding equipment. Grounds shall be installed so that at least one set is visible to one member of the crew, unless one of the grounding devices is accessible only to authorized persons. Grounding devices shall be placed so that employees cannot make accidental contact between the grounding devices and unprotected energized conductors. When working on new lines or equipment under construction or on existing de-energized conductors or equipment, jumpers shall be installed to ensure that no potential difference exists between the equipment being worked upon and any grounded conductors or equipment which might be contacted while the work is in progress. On grounded steel structures, a personal ground shall be installed between each de-energized conductor being worked upon and the steel structure. Before opening or closing any conductor that may be exposed to a difference of potential or that has been grounded to a primary neutral, approved jumpers shall be in place across the point to be opened or closed to ensure continuity of the conductor. When splicing overhead conductors at ground level that are exposed to hazardous differences in electrical potential, an Equal Potential Zone (EPZ) mat shall be used, or a ground shall be installed on each side and within ten feet of the working area. The two ends being spliced shall be bonded together with an approved jumper. When it is necessary for employees of other Business Units to work in substations or generating stations on lines or equipment where portable grounds are required they shall be supplied by the substation or generating station. Whenworkistobedoneononede-energizedcircuitofamultiplecircuitlineatthesame level and the circuits are separately bonded, tests shall be made to determine that no appreciable difference of potential exists between the grounded conductor and the bond of the circuit to be worked upon. Whenworkingonorclimbingthroughenergizedmultiplecircuitsthatarecommonlybonded and it is impossible to avoid personal contact with the bond, the bond shall first be grounded before the lineman climbs through or works on the circuit. 13. When work is to be done or contact made on the bond or metal fixture of either a Dreyfuss or squirrel cage fixture supporting energized conductors, it must be done with live line tools or the fixture must be grounded. If the bond wire is #4 copper and is exposed so it can be inspected, only one fixture need be grounded. If not, approved jumpers are required between fixtures. NOTE Nothing in this rule shall prohibit working on conductors with approved insulated tools or equipment. 14. Stationgrounddisconnectsshallnotbeconsideredforuseasapprovedpersonalgrounding devices.

Operating Underground Switches a. The opening or closing of energized switches or cutouts in an underground vault, manhole, CST enclosure, or similar structure, shall be performed remotely. When switching remotely, employees are required to maintain a minimum of 15 feet between any part of their body and the face the opening of the underground structure, including vent pipes. If remote operation is not possible, the source shall be de-energized by means of an adjacent switch, C.B., and so forth, where remote switching can be accomplished. EXCEPTION: A switch may be considered de-energized, for the purpose of switching only, when all of the following conditions exist: The switch contains only one circuit and is in a dead section of line as verified through the Switching Center. Rules Rule 309, b., c., d., e., f., and f. have been complied with. NOTE See the Electric Distribution Remote Operation of Underground Switches Manual and Maintenance and Procedures Manual for additional operating instructions and approved equipment. Each step of routine or emergency switching shall be verified by two qualified employees at the work location. EXCEPTION: One qualified electrical worker in a classification that normally works alone, and who is trained in "self-tailboard", may verify each step of switching and operate energized "above ground" switches such as pad mount or PMH type switches, or other switches located on pads. For automatic circuit recloser operations (see Rule 316). Locate, identify, and mark the position to be switched. Check all the existing positions of the switch and compare to the circuit map, switch schematic, and cable and/or equipment tags to ensure that the switching order will accomplish the desired results. NOTE Cable tags are the preferred method. When encroachment is an issue of concern, equipment tags may be used as a secondary method. If switching on a "RAC" type switch, a blocking device or special handle must be used to ensure that the switch is operated only to the desired position. When switching energized underground single-phase fuses or disconnects in live front PMH type equipment, an approved protective shield shall be affixed to the grip-all stick. This also includes switching in single phase padmounted fuse cabinets. This does not apply to equipment where the fuses or disconnects are required to be de-energized (see Rule 304). h. Switching shall be performed remotely. Employees are required to maintain a minimum of 15 feet between any part of their body and the face of the padmountor the opening of the underground structure, including vent pipes. If a Safe Standoff Distance (SSD) of 15 feet cannot be maintained, the switching would have to move to the next upstream device where the minimum SSD can be maintained. NOTE Safe Standoff Distance (SS) is a pre-identified distance that is away from the device being operated and any additional hazards including associated vent pipes. An arc/flash blanket properly secured around the vent pipe may be used to reduce flash hazards from the vent pipe. All S&C and Scott Engineering PMH live-front load-drop fused positions shall have the source to the line side of the fused position de-energized prior to opening the fuse position.

Working in Elevated Positions Before climbing poles or structures, employees shall familiarize themselves with the circuits, voltages, apparatus thereon, and any unusual conditions which might present a hazard. Not more than one employee shall ascend or descend a pole at the same time. The first employee shall be in place on the pole or on the ground before the next employee climbs or descends the pole. When it becomes necessary for one employee to work above the other, extreme care shall be exercised. Before climbing poles, ladders, scaffolds, or other elevated structures, or riding span wires, messengers, or cables, or entering cable cars, boatswain chairs, or the like, employees shall first assure themselves that said structure or device is strong enough to safely sustain their weight. Before allowing employees to work on any pole from which supporting wires or guys are to be removed, or on which in any way the stress is to be changed, the employee in charge shall make sure that the pole will stand the change in stress without falling. If it is necessary to test the pole, see Rule 202. When the condition of the pole to be worked on is in doubt or when it is not practicable to test, the pole shall be supported before work is started. Employees shall observe height nail or pole brand to make certain that the pole is set to proper depth. (Manufacturers usually place their pole brand 10 feet from the butt end of the pole on 25-foot to 60-foot poles and 13 feet from the butt on all poles 65 feet or longer.) Employees shall not transfer from aerial buckets or baskets to a pole or structure. Transfer from an open platform to poles or structures are permitted. Climbers shall not be worn while performing work from an aerial lift. Neither the bucket nor boom shall be allowed to contact unprotected energized conductors. This does not preclude the use of attachments to the boom specifically designed to support energized conductors. When using power tools, grounded material or equipment such as wire, cable, personal grounds, electric cords, and so forth, approved for use on erected poles, towers, or structures, the tools and all electric supply lines connected thereto shall be kept a safe distance under the level of circuit or apparatus energized in excess of 600 Volts or shall be adequately guarded or secured in such a way as to prevent their contacting energized conductors. Only approved portable power saws shall be used from elevated positions on erected poles.

306

Working on De-Energized Cables Cable or equipment to be worked upon shall be positively identified by tags, duct location, maps or approved testing means before work is started. Work will then be performed as indicated in Rule 306, b., c., d., and/or e., as appropriate. Cable and equipment shall be considered energized and worked with adequate protective devices until it has been tested de-energized with an approved device for indication of voltage and grounded with approved ground devices. Clearances, if required, shall be obtained in accordance with established procedures. After de-energized and before proceeding with the work on all power supply cables normally energized in excess of 600 Volts, all conductors shall be short-circuited and grounded according to Business Unit procedures. Between the place where the work is being done and each possible source of supply, or At the work location, or As close as practicable to the source of supply. Cables normally energized at more than 600 Volts shall be spiked, or grounded at the work location. When cable is to be spiked, it shall be done so all employees are remote from the spiking operation, that is, from outside, an enclosure, walk-in vault, underground structure or excavation. The foregoing procedure shall be followed to prove any normally energized cable is de-energized before opening the sheath. All switches through which it is possible to energize the power supply cable to be worked upon shall be opened and tagged.

305

Working on Energized Cables Cables energized at more than 600 Volts shall not be cut or spliced while energized until permission has been granted by the Supervisor in charge. Rubber gloves shall be worn while performing the following work on conductors energized below 7,500 Volts. Cutting or removing metallic sheathing, semiconductor, or shielding; Removing or applying insulation; Working on bare conductor. Before removing a section of metallic sheathing or semi-conductor from cables energized above 600 Volts, both sides shall be bonded together with a metallic jumper. When working on energized underground conductors or parts of energized equipment, adequate barriers or suitable protective covering shall be provided to prevent accidental contact with other conducting surfaces, including grounds. Live line tools shall be used when installing or removing taps between the concentric neutral conductor and any grounding point if the neutral is in service. For the purpose of this rule, the neutral will be considered in service at all times after its initial installation. All work on energized loadbreak components shall be performed by the policies addressed in Rule 312 b..
