form) as approved by the municipality; such plan to show the grading, layout and dimensions of lots, sidewalks and curbs, and the location of all other utilities and other underground structures. • Install lot boundary pins or markers in the area under development prior to the start of trenching for the URD. • Notify the Company of the completion of rough grade, installation of other facilities at grades below URD and the schedule of desired electric service connections so that the Company will have adequate time to install its facilities. • Provide trenching and conduit or conduit systems as required. See paragraph 901 for a list of such requirements and paragraph 910 for conduit requirements/specifications. 908. PADMOUNT TRANSFORMERS Installation of padmount transformers is limited to cases meeting the following specifications: 1. Single-phase three-wire services, (a) operating at 120/240 volts and requiring transformer capacity of not more than 167 kVA, or (b) operating at 240/480 volts and requiring transformer capacity of not more than 50 KVA; or 2. Three-phase four-wire services operating at 120/208 volts or 277/480 volts Wye and requiring transformer capacity of not more than 2500 KVA. (Larger units may be available by special arrangement.) 75 75
76 76 In cases not meeting the preceding specifications, the customer shall provide a Company approved transformer vault or yard. Additional information will be furnished upon request. Padmount transformer foundations must be supplied by the Customer and pad designs must conform to Company specifications to ensure interchangeability with spare transformers. See Illustrations No.s 23, 24, 25 and 26 in Section XII. Padmount transformer locations shall be graded for proper drainage and that drainage shall be maintained by the customer. In addition, the location must be readily accessible by truck at all times without causing site damage. A ¾ inch by 8 foot galvanized ground rod will be furnished (available at the local Service Center) by the Company and installed by the customer. It is to be located 6 inches in front of the left front corner of the foundation. The ground rod should be left 6 inches exposed above grade until all ground connections are made and inspected. Prior to back filling around the foundation base, the customer will furnish and install a bare #4 stranded copper for grounding of the transformer. The conductor must be of sufficient length (10 ft. of grounding conductor will be required for single-phase and small (7’ x 7’) three-phase installations, larger three-phase (9’ x 9’) or greater will require 20 ft. of grounding conductor) to connect the transformer neutral and ground to the ground rod. The conductor will extend from the interior of the base, through the ground wire hole (if available) or one of the cable holes (bond outs) in the wall of the base, to the ground rod location. It is NOT to be installed on top of the base or slab (foundation) such that the transformer or slab will bear directly on the conductor.
