Our industry has made numerous technological advances designed to protect homeowners, businesses and electrical workers. That makes every fatal electrocution in the home all the more distressing. Between 2010 and 2013, the U.S. saw an estimated average of 48 electrocution fatalities associated with consumer products per year, with large and small electric appliances chief among them1. Tragedies like these can be avoided, especially when the ground fault circuit interrupter (GFCI) technologies needed to prevent dangerous events are readily available. As the principle NEMA representative at the National Electrical Code (NEC) Code-Making Panel Two, I saw public input asking for increased GFCI protection for the home during the 2017 code cycle. The code panel expanded the GFCI requirement for facilities other than dwelling units as part of section NEC 210.8(B). However, residential standards improvements were sidelined.

Code updates happen for one main reason: safety improvement. NEC (National Electrical Code) Article 408.3 helps take electrical safety for service entrance panels to a new level. The code, updated in 2017, includes provisions to provide shock protection via panelboard barriers. The barriers protect from energized conductors on the line terminals of the main overcurrent protection device (OCPD) in a panelboard. When the main circuit breaker in a panel is turned off, line side terminals and conductors remain energized from upstream via the utility or another panelboard. With these barriers in place and the main OCPD turned off, installers are better protected when pulling wires into the panelboard. Today, all panelboards are shipped with shock-protective barriers. However, barriers are new to installation procedures, so contractors may not recognize them and accidentally throw them out—easily and often.

We’re all human and we all make mistakes. But mistakes in the electrical field can prove costly. Codes and standards work together to reduce mistakes and save lives, which is what makes NEC (National Electrical Code) Section 240.87, Incident Energy Reduction, so significant.

When working with data center and commercial facility electrical systems, shocks of 100mA to more than 2,000mA are possible—definitely in the realm of serious harm to humans and property. Energized electrical equipment also presents the risk of arc flash caused by electrical faults that produce powerful explosions. When dealing with commercial and industrial electrical systems, such as uninterruptible power systems (UPSs) and their batteries, data center and facilities managers need to be aware of these risks, especially since some repair and maintenance procedures require working with a unit that is still energized. There are ways to minimize the risks to employees, equipment and the field technician performing the service. This paper answers some common questions about UPS maintenance, how to reduce the risks associated with servicing UPSs and batteries, and how to qualify a UPS service provider.

Arc flashes—the fiery explosions that can result from short circuits in high-power electrical devices—kill hundreds of workers in the U.S. every year and permanently injure thousands more. They can also wreak financial havoc in the form of fines, lawsuits, and damage to expensive equipment. This white paper aims to fill that knowledge gap by providing introductory-level information about what arc flashes are and what you can do to prevent them.

This white paper discusses the issues making data center cooling more challenging than ever and explains why starting the data center design process with the racks rather than the room can help businesses reduce energy consumption, increase capacity and optimize floor space utilization.

Cloud computing vendors and colocation data centers make every effort to maximize the scalability, efficiency and agility of their data centers. As a result, more and more of them are looking into replacing older, transformer-based centralized power protection schemes with distributed architectures in which uninterruptible power systems (UPSs) reside in the white space (or data hall). This white paper describes the advantages of positioning UPSs in the white space as well as the essential qualities to look for in a white space-ready UPS.

This white paper explains why many data centers are ill-equipped to support today’s most important new technologies; discusses why packaged power and cooling solutions can be a flawed way to upgrade existing facilities; and describes the core components of a data center upgrade strategy capable of enhancing efficiency and power density more completely and cost-effectively.

When designing a power protection scheme for their data center, IT and facilities managers must ask themselves whether a distributed or centralized backup strategy makes more sense. Unfortunately, there is no easy answer to that question. Companies must weigh each architecture’s advantages and disadvantages against their financial constraints, availability needs and management capabilities before deciding which one to employ. This white paper will simplify the decision-making process and lessen the potential weaknesses of whichever strategy you ultimately select.

This white paper discusses the forces shaping today’s data centers and describes the capabilities businesses should look for when selecting PDUs.

Though power protection solutions vary in numerous ways, all but the largest data centers use basic approaches when deploying uninterruptible power systems (UPSs): Either they distribute many smaller UPSs among their server racks or they install one or two large UPSs centrally within or near their server room. This white paper outlines each architecure's pros and cons.

Server virtualization empowers businesses to lower hardware spending, simplify administration and boost availability. For IT and facilities managers, however, it introduces challenges and opportunities.

For all their advantages, virtualization and cloud computing bring some unique challenges: higher power demands per server and enclosure, more critical applications residing on each server, and a need for greater visibility into power conditions.

This white paper aims to fill that knowledge gap byproviding introductory-level information about what arc flashes are, why they're so hazardous and what steps data center managers should take to safeguard their employees and infrastructure.

Budgeting for electricity, securing adequate supplies of it and finding ways to use less of it are all common topics of conversation among data center operators. Ensuring that the power their IT resources rely on is both dependable and clean, sadly, can sometimes be an afterthought.

Server virtualization empowers businesses with significant advantages that include reduced hardware expenses, simplified administration and heightened availability. As a result, nearly 80 percent of server workloads supported by x86 hardware are now running on virtual machines, according to Gartner estimates. However, despite its widespread adoption and benefits, the technology is not without its challenges.

Not so many years ago, network closets, server rooms and data centers were designed from a “room to rack” standpoint. Deciding specifically where to store your technology typically came later in the design process. However, rapid technology refresh cycles, the need to rackmount more equipment and the desire for increased cooling capacities in an enclosed rack (known as an enclosure), have all begun to reverse that trend. Today, IT professionals are designing these critical workspaces with more of a “rack to room” methodology.
