During the recent 2017 National Electrical Code (NEC) first revision meetings in Hilton Head, S.C., a number of public inputs were submitted to introduce a new cabling system into Article 725 and Article 760.
Data center connection is one of the most common uses for dark fiber, and it’s all due to growing data needs. You have probably seen graphs of the Internet’s growth and heard claims about how much data moves along it.
Some cabling industry stakeholders predict the imminent death of copper cabling, while others disagree. However, most agree that fiber optical networks are taking a large bite out of the new network market.
Working with and around electricity poses hazards that most people don’t face in their daily jobs. From apprenticeship training throughout their careers, safety training is a continual process for electricians.
Times are changing for the electrical contractor (EC). The trend even affects the basics. As Electrical Contractor focuses on the latest developments in cabling and controls, the 2014 NECA Show in Chicago, Sept.
As with any project, a communications cabling project requires comprehensive management. Project management for cabling or related networks is best understood when broken into five subtopics: Planning, Design, Installation, Testing and Operation.
A life-threatening event occurs at a large building where many people could be in danger. In this case, it is a smoky fire, but it could also be an earthquake or a mass shooting. The fire alarm system senses the fire, locates the problem, and immediately begins sending signals.
Last month, I covered the challenges to traditional structured cabling from multimode optical fiber and wireless. Multimode fiber became the favorite cabling for the backbone but never made it to the desktop because every connected device already had a free Cat 5 port.
This is the first in a series of columns on networks and cabling—media, really—as we explore the nature of networks, their cabling needs and how they have evolved to provide for today’s “always connected” society.
Termination of installed optical fiber cables has always been perceived as a difficult, expensive, time-consuming process that discouraged some contractors from developing in-house capability for fiber installation.
For low-voltage contractors eager to seize more market share in the residential sector, home automation may be where ground can be gained. A BCC Research study revealed that the U.S. market for home automation systems and devices is expected to see strong growth over the next several years.
Experienced low-voltage contractors know that there is more to taking an integration and wiring plan through to installation than just following a schematic—it is about marrying the theory of what the customer wants with the hands-on reality of how structured cabling fits into and supports a wider s
Electrical contractors are familiar with the cabling installation requirements of NFPA 70 2011, the National Electrical Code (NEC), and some are familiar with the cabling requirements of NFPA 72 2010, the National Fire Alarm and Signaling Code.
Low-voltage contractors who are keeping abreast of developments in their industry know wireless technology is in the process of moving to its next generation of wireless access, which will be defined by the IEEE standard 802.11n.
