Pathways

Pathways
Cable Pathways allow for the placement of cables in buildings. They can include cable trays, cable ladders, firestops, sleeves, cable management, under floor, over floor, poke thru, raceways, and “J” hooks. When planning any cable plant you should always consider growth, installed weight, and future access to and from your pathway. When designing your pathway you should also consider 90-degree bends and dropouts. Let Gallant & Wein can help you with design and implementation of your cable Pathway System. needed.
About Pathways
Electrical and low voltage cabling are an integral part of all building systems and must be extensively routed throughout all building types. The governing code for all electrical pathways is NEC NFPA 70. There are many options available for cabling Pathways. The first step to choosing any pathway system is to understand the wire that is being installed. The common types of wiring used in pathways are: 1,000 volts or less, Class 1, Class 2 and Class 3 circuits as designated by the NEC.
There are several design considerations used to provide the best pathway for a cable type. These considerations are: accessibility, pathway support requirements, distance that the pathway will travel, special protection requirements including grounding and bonding and the quantity of cables that must be supported. Accessibility is one of the most important factors in any pathway system and is outlined in the NEC. Often, junction boxes or drop outs are used to provide a point to transition or access to maintenance of your pathway.
Should my cable tray be grounded?
Yes, There are many articles and tips on bonding and grounding your cable tray system in the NEC CODE BOOK. Refer to sections-250 and 318 for reference.
Can I run network cable and power cable in the same cable tray?
Current standards clearly define the separation between power and data cables. For instance, the minimum separation distance between unscreened power and unscreened UTP cable is 200 mm. ... Electro-magnetic interference from power cables can reduce the performance of data cables, particularly speed of data transmission
Can data cable and power cable be run together in a power pole?
Yes. Hubbell makes power poles with center dividers for this application
