Conduit Requirements for CCTV Cameras Mounted on Light Poles

Closed circuit televisions (CCTVs) mounted on exterior light poles are subjected to many specific conduit requirements, according to the North Texas Tollway Authority. Electrical and non-electrical wires running to and from CCTV devices must be secured within fully secured piping and should be attached to non-breakable poles. Poles may also be situated adjacent to building facades and require additional specifications set by the National Electrical Code.

Galvanised Rigid Steel

All CCTV and other above ground conduit should be composed of galvanised rigid steel, according to NTTA. Interior and exterior sides of conduit must be galvanised and coated with PVC to extend the life of the steel. Specifically, steel should be first sealed with zinc and covered by PVC gloss. Flexible steel -- for bending around pole bulbs or other structures -- must also be coated with PVC sealant and no two conjoined pipes can bend in degrees equalling or exceeding 360 degrees.

Liquid Tight Conduit

All conduits must be liquid tight preventing against dipping, leakages or inclement weather, according to NTTA. Conduit must be placed in ways that prevent drainage to occur and drainage tees should be attached at the base of light pole conduit installations to help the materials drain appropriately. All vertically installed conduits should project outward from the structure at a distance of 2 inches to eliminate water and other liquid or debris from funnelling into piping.

Base Installations

Conduit at the base of a light pole and extending into the ground must meet additional specifications, according to NTTA. Conduit entering into concrete surfaces must be positioned at least 8 inches inside of base edges. A maximum of two separate conduits -- both with 2-inch diameters -- are permitted at all individual light pole bases. All galvanised steel edges -- whether conduit is installed at bases and/or along pole facades -- must be polished to eliminate jagged edges or kinks.
