When selecting a facilities wiring system, the potential for the wiring system to allow moisture to flow into the electrical equipment enclosures should be evaluated. This is true for all wiring requirements: electrical power, instrumentation data, c[……]
All materials expand and contract due to temperature changes. It is important that cable tray installations incorporate features which provide adequate compensation for their thermal contraction and expansion.
1993 NEC Section 300-7 (b) states tha[……]
Cable tray wiring systems have conductor advantages over conduit wiring systems where the installations involve phase conductors installed in parallel.
For large ampacity circuits, the most practical wiring system installations are those where rea[……]
Both the communication and power distribution industries are largely dependent on cable management as because the wires that are used for distributing power and other purposes need to be interweaved and extended in a manner so that fire outbreaks and[……]
A common type of material, which used to hold or support wires safely inside a high-rise building, is generally considered as a Cable Tray. These trays help to provide a right path to the wires, so, that they cannot create a barrier in between the wo[……]
When it comes to cable management, debates over the suitability of one solution over another are commonplace, but when it comes to the pros and cons of perforated cable tray in relation to wire mesh things can become heated. In order to get a balance[……]
Okay, we got it. Structured Cabling isn’t sexy. In fact, it is pretty down right boring, but in today’s world, even the smallest of businesses have to be smart when it comes to their cabling and network design.
Building construction has failed to keep pace with productivity improvements found in other segments of the economy. According to the U.S. Bureau of Labor Statistics, nonfarm (manufacturing) productivity has improved 200 percent since 1964 while[……]
