ELECTRICAL JUNCTION BOXES -1 DESCRIPTION Provide a stackable in ground junction boxes made from fiberglass reinforced polymer concrete or thermoplastic materials and provide cast-metal boxes encased in concrete of the appropriate type at locations noted in the plans, complete with all necessary covers, conduits, duct and hardware, in accordance with the contract. -2 MATERIALS Refer to Division 10. Item Section Backfill 1005 Electrical Junction Boxes 1091 -5 Provide a n in ground junction box which is open bottom with a foot. Provide a standard “Lighting ” logo on the cover unless specifically noted otherwise in the plans. Backfill beneath and around the boxes using #67 washed stone in conformance with Section 1005. -3 CONSTRUCTION METHODS Install conduits and duct before the in ground (IG) boxes are set in place. Do not rest the bottom of the box directly on conduits, ducts or cables. Place the t op of the box on the same grade as the surrounding area. Perform backfilling with sufficient care that no part of the junction box, conduit or duct is displaced or moved out of alignment. Backfill beneath and around the box to at least 12 inches using #67 washed stone aggregates in conformance with Section 1005. Locate junction boxes for best routing of conduit and duct and to minimize drainage problems. Any junction boxes which are retaining water as identified by the Project Inspector or the Lighting a nd Electrical personnel during final inspection shall be corrected to the satisfaction of the Engineer prior to project acceptance. Do not locate junction boxes in useable shoulders or pavements or other areas where they may be subjected to continuous traffic loadings. Stub the ends of conduit and duct vertically. Temporarily seal ends of conduit and duct until feeder circuit conductors are installed. Leave approximately 10 inches from the top of the conduit to the junction box lid. Arrange wiring so that splices will not lay in the bottom of the box.
