635-3 Installation.
635-3.1 General: Do not install power and communication cables in the same bo x unless
otherwise shown in the Plans. When signal or 120 volt (or greater) power is present, ground all metal covers in accordance with Section 620. Ensure metal junction boxes are grounded and bonded in accordance with the NEC Section 314.4.
635-3.2 Pull and Splice Boxes: Install pull and splice boxes in accordance with Standard
Plans, Index 635-001. Ensure pull and splice boxes are sized for the amount of cable to be placed inside. Ensure that the pull or splice box cover is flush with the co ncrete apron or sidewalk. Do not install pull or splice boxes in roadways, driveways, parking areas, or public sidewalk curb ramps. Avoid placing pull and splice boxes in low -lying locations with poor drainage. Ensure that pull and splice boxes house fiber optic cable without subjecting the cable to a bend radius less than 14 times the diameter of the cable. Install identification plates according to the box manufacturer’s instructions.
635-3.2 1 Placement and Spacing: Place pull and splice boxes as shown in the
Plans and at the following locations, unless directed otherwise by the Engineer:
635-3.2 2 Electronic Box Marker: Equip all pull and splice boxes buried below
finish grade with an electronic box marker inside the pull or splice box to mark the location. Ensure that the electronic box marker i s a device specifically manufactured to electronically mark and locate underground facilities. Ensure that the electronic box marker includes circuitry and an antenna encased in a waterproof polyethylene shell. Ensure that the outer shell is FY 2023-24 Return to Table of Contents impervious to minerals, chemicals, and temperature extremes normally found in underground plant environments. Ensure that the electronic box marker does not require any batteries or active components to operate. Ensure that electronic box markers used to mark fiber opti c cable and general telecom applications are orange in color and operate at 101.4 kHz. Ensure that the electronic box marker’s passive circuits produce an RF field when excited by a marker locator to direct the locator to the marker’s position. Ensure that the electronic box marker has a minimum operating range of 5 feet from the marker locator.
635-3.3 Aerial Junction Boxes: Install aerial junction boxes in accordance with Standard
Plans, Index 634-002.
635-3.4 Mounted Junction Boxes: Install mounted jun ction boxes in accordance with
