Article 430 of the National Electrical Code (NEC) covers motors, motor branch-circuit and feeder conductors, motor branch-circuit and feeder protection, motor-overload protection, motor-control circuits, motor controllers, and motor-control centers.
In February 2014, the U.S. Department of Energy (DOE) announced new energy-efficiency standards for ballasts sold as part of new metal-halide luminaires, which are commonly used for illumination in parking lots, roadways, warehouses, big-box retail and floodlighting. Compliance is required by Feb.
The modern movement toward more sustainable-energy practices has touched almost every aspect of our daily lives. From renewable power to electric vehicles (EVs), few of these changes have gone unnoticed, and the trend affects almost everyone in one way or another.
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.
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!”
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).
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.
