1.0 General A. Introduction

B. Pedestal and Pole-Mount Cabinets

1.1

The 3M™ Modular Hardwire Cabinets 4300 1.3 Series provide a point for cross connections between feeder and distribution cables of diameter 0.7 mm–0.32 mm (22–28 AWG). Frames within the cabinets hold banks of preconnectorized 25-pair feeder and distribution blocks. Blocks can either be installed initially or added at a later date with no disruption of existing circuits.

1.2

Jumpering is accomplished using 0.7 mm (22 AWG) plastic insulated wire which is run from 1.4 feeder binding posts to distribution binding posts. Wire raceways are provided for protection of all 1.5 jumper pairs as they are installed.

Due to the terminal sizes and frequency of installation visits, the cabinets should be located as specified by the engineering plan. The cabinets should be located in unobtrusive locations acceptable to the property owners and where they are reasonably protected from damage by motor vehicles and other machinery. They should be 1.5 m (5 feet) from utility poles and at least 0.3 m (1 foot) from buildings, fences, or other objects considered to be potential lightning attractions. The cabinets are constructed of galvanized steel with a gray/green baked enamel finish. The pedestal cabinets feature a ventilation system whereby the vents may be open or closed depending on local condensation conditions. Overall Dimensions
