As wireless deployments continue to keep electrical contractors (ECs) busy, installers are seeing increased diversity in the type and scope of these projects. One reason is the greater reliance on wireless networks. Another is the introduction of the latest wireless standard, 802.11ac.
At the Greenbuild conference in November 2013, the U.S. Green Building Council (USGBC) released the fourth generation of the Leadership in Energy and Environmental Design (LEED) green building rating system.
Energy management is becoming commonplace in today’s electrical infrastructures through the control of utilization equipment, energy storage and power production. Yet, limited consideration is found in electrical installation standards to actively manage these systems.
In late 2012, the California Energy Commission (CEC) published a voluntary specification recognizing quality light-emitting diode (LED) lamps intended to replace screwbase incandescent lamps in luminaires.
Electrical contractors plunging deeper into the security market need to pay as close attention to the standards involved in security systems and attendant technologies as they do to the National Electrical Code (NEC).
When I am performing construction administration services for my clients and ask contractors why they installed the fire alarm system the way they did, they often lament, “That’s all the code required!”
Installation requirements for arc-fault circuit interrupters (AFCI) in 210.12 of National Electrical Code (NEC) have been modified considerably in the past three NEC cycles and have changed dramatically in the 2014 NEC.
In my last column, I discussed the ICC code process. This month, I look at the NFPA process. As I previously mentioned, the ICC and NFPA have completely different processes for codes and standards development. Yet, both operate on three-year cycles.
We all know our an industry is governed by codes and standards. While many complain about some of the requirements, few try to do anything about it. We all have an opportunity to fix things that we don’t like. Most people don’t understand the process or believe they can have any effect.
It makes sense that most contractors focus on the codes that relate to the system types they install. Specifically, professional systems contractors most use NFPA 70, National Electrical Code and NFPA 72, National Fire Alarm and Signaling Code.
Debates within the organizations that develop the power quality standards will probably continue for years about why “power” isn’t really the subject of the standards. The majority of the standards present how to measure, monitor, characterize, categorize and set limits on voltage.
If you have a problem related to the National Electrical Code (NEC), are experiencing difficulty in understanding a Code requirement, or are wondering why or if such a requirement exists, ask Charlie, and he will let the Code decide. Questions can be sent to email@example.com.
