27 Temporary Service 4 Section 4 Heading Page Basic Requirements 4-1 Temporary Service for Construction Work 4-1 Construction Criteria for Temporary Service 4-1 Construction Requirements for Temporary Service 4-2 PGE Gold Temporary Service 4-11

28 Temporary Service 4 4 Temporary Service 4.1 Basic Requirements Upon request, PGE will supply temporary service at a location adjacent to PGE facilities as provided for in appropriate electric service schedules. Consult PGE for information regarding temporary construction service programs. Always locate a temporary service for construction work so that the meter is protected from accidental damage. Where practical, place the temporary service in a location that is usable throughout the construction period. When PGE must relocate a temporary service, the Customer must bear the relocation cost in accordance with the PGE schedule of charges. The service pole and service post must be sound and in good condition for the duration of its use. PGE will not energize a temporary service if the Customerprovided service pole is not safe to climb, or if the service post is not suitable for supporting the tension of the service conductor. NOTE: A service pole is round; a service post is square. Overhead temporary services must meet the clearance requirements provided in this section and in Section 5, Clearances. Underground temporary cables must be placed in a trench meeting the requirements of Section 6, Underground Requirements. Temporary service cables laid on the ground, even with mechanical protection, shall not be permitted. 4.2 Temporary Service for Construction Work Temporary service for construction work can be set up in one of five typical structures. a 6- x 6-inch overhead service post in a nonroad crossing a 6- x 6-inch overhead service post in a road or traffic crossing a 4- x 4-inch overhead clearance post overhead service pole underground service, 4- x 4-inch post mounted 4.3 Construction Criteria for Temporary Service Temporary structures must meet all of the following construction criteria before PGE can provide service. PGE has the right to refuse connection if height, strength, bracing, or other requirements are not met. The pole, post, and stakes must be pressure- or thermally treated with an approved American Wood Preservatives Association standardized preservative. A steel stake may be used in place of a wood stake. All posts, poles, and stakes must be one continuous piece. Using more than one piece of wood to construct a pole, post, or stake is not acceptable. 4-1

29 4 Temporary Service To ensure strength, all lumber must be free of any sucker knobs and have spike knots no larger than one third of any face. Checks greater than 0.5- inch wide are not permitted; no visible wood decay is allowed. Set the stakes in undisturbed soil. Each stake must be attached to the brace using three 16d or greater (penny) nails; the brace must be attached to the post with a minimum of three 16d or greater nails. If a steel stake is used, a U-bolt may be substituted for the three 16d nails. Use tamped, 3/4-inch minus crushed rock at a depth that equals the required depth of the pole or post to provide stability. Installation of a service post for temporary construction power requirements cannot exceed 180 days of use. If temporary construction power service is needed beyond 180 days, an overhead service pole must be provided. A service conductor that crosses a road or traffic area is required by the NEC and NESC to have a higher aboveground clearance. This requires the installation of an overhead service pole or an overhead service post as specified in Section The distance between the electric utility point of attachment and the temporary service pole or 6- x 6-inch post must be 60 feet or less. If the distance between the electric utility point of attachment and the temporary service pole or post is greater than 60 feet, then a 4- x 4-inch overhead clearance post shall be used to ensure adequate clearance. An electrical permit and inspection by the local code enforcement agency is required for all temporary services. The code-enforcing agency may require that the grounding connection be visible when the electrical inspection is made; however, for safety reasons, the top of the ground rod should be flush with or belowground level. 4.4 Construction Requirements for Temporary Service Follow these construction requirements for all types of overhead and underground temporary service. The meter socket must be NEMA type 3R (rainproof) and in good condition with no holes, bends, or damage and must be plumb in all directions. Service equipment must be NEMA type 3R (rainproof) and in good condition with no holes, bends, or damage. NEC-approved covers must be properly secured. The center of the meter socket must be a minimum 4 feet and a maximum 6 feet from the ground level. Attach the electrical label or permit to the meter base. See Section 5, Clearances, for service drop and, where applicable, drip loop clearances x 6-Inch Overhead Service Post Follow these additional construction requirements for an overhead service post. 4-2

30 Temporary Service 4 A minimum 4-AWG-aluminum triplex conductor suitable for tensioned overhead service is required and must be long enough to reach the ground. Use a wedge grip and an eyebolt or insulator spool to attach the triplex conductor to the top of the post. See Figure 4-1 for an overhead service in a nonroad crossing; see Figure 4-2 for an overhead service in a road or traffic crossing. Make sure that the braces do not block the working space around the meter or service equipment. The customer is responsible for the conductor from the meter base to where it reaches the ground x 6-inch Overhead Service Post in a Nonroad Crossing Follow these additional construction requirements for an overhead service post in a nonroad or traffic-free crossing. See Figure 4-1. The post must be 6- x 6-inch square, a minimum of 16 feet in length, and set in the ground a minimum of three feet. NOTE: When a temporary service post is within 25 feet of the PGE service drop, a 4- x 4-inch post can be substituted for the 6- x 6-inch post. The braces must be 2- x 4-inches and a minimum of 12 feet in length. The stakes must be 2- x 4-inches and set in the ground a minimum of two feet. A 3/4-inch round, steel stake set in the ground the same depth may be substituted when ground conditions prohibit driving a wood stake. See Figure 4-3 for a steel stake and U-bolt x 6-inch Overhead Service Post in a Road or Traffic Crossing Follow these additional construction requirements for an overhead service post when the service drop crosses a road or traffic crossing. See Figure 4-2. The post must be 6- x 6-inch square, a minimum of 24 feet in length, and set in the ground a minimum of four feet. The braces must be 2- x 4-inches and a minimum of 18 feet in length. The stakes must be 2- x 4-inches and set in the ground a minimum of three feet. A 3/4-inch round, steel stake set in the ground the same depth may be substituted when ground conditions prohibit driving a wood stake. See Figure 4-3 for a steel stake and U-bolt. 4-3

The stakes must be 2- x 4-inches and set in the ground a minimum of two feet. A 3/4-inch round, steel stake set in the ground the same depth may be substituted when ground conditions prohibit driving a wood stake. See Figure 4-3 for a steel stake and U-bolt. Maintain a maximum of 60 feet between the posts. Maintain a minimum of 8 feet between the post and the stake. 4-6

Follow these additional construction requirements for an overhead service pole. See Figure 4-5. A minimum 8-AWG-copper or 6-AWG-aluminum conductor is required. The conductor must be 24 inches in length outside the weatherhead. 4-7

35 4 Temporary Service The pole is to be 20-foot minimum in length, not less than 5.5 inches diameter at the top. If the service drop crosses a road or traffic area, the pole is to be 25-foot minimum in length. Set the pole a minimum of 10 percent of the length of the pole plus two feet belowground level with gravel backfill. For example, a 20- foot-long pole would be set four feet belowground level, a 25-footlong pole would be 4.5 feet belowground level. The Customer must provide a 5/16-inch galvanized steel guy. PGE to bond the down guy to the service neutral and ground conductor. PGE will not energize a temporary service if the Customer-provided service pole is not safe to climb. 4-8
