Emergency, Standby, Backup
NFPA 70-2017: The National Electrical Code (NEC) has many requirements that apply to designing electrical systems for health care facilities. It’s vital to understand the changes in the 2017 edition in order to stay code-compliant.
Six electrical, power system survey findings
Consulting engineers who specify emergency power equipment understand that installations for mission critical facilities, such as hospitals and data centers, are required to comply with NFPA 110: Standard for Emergency and Standby Power Systems in conjunction with codes such as NFPA 70: National Electrical Code (NEC). This article will review the most recent version (2016) of NFPA 110 and offer tips for compliance.
This article discusses design requirements of NFPA 110 (2016) and how it applies to emergency and standby power systems in mission critical facilities. It also reviews other relevant codes, such as NEC (2017), NFPA 99 (2018), and IBC (2015), and discusses how they complement NFPA 110.
Hospitals, clinics, and similar facilities are among the most demanding an engineer can tackle—technology is evolving rapidly, hospital managers are increasingly budget-conscious, and assist in saving lives. Here, electrical, power, and lighting challenges are addressed.
The coordination of requirements for emergency and standby power systems between different code publications has improved over recent years, but variations still exist that can cause confusion. It is important for engineers to review all the applicable codes and standards to develop a full picture of the requirements for standby systems. While NFPA 110-2019: Standard for Emergency and Standby Power Systems defines system levels, types, and classifications, it does not determine what situations will require any given level, type, or class. Design engineers must coordinate the requirements of NFPA 110 with other sections of the NFPA, International Building Code, Facility Guidelines Institute, and other authority having jurisdiction requirements as applicable.
As technology advances in every field, the college and university students being prepped for future careers in those fields need the tech they’re learning with to keep up. That presents unique challenges for the engineers working on such structures—specifying advanced systems that satisfy the unique needs of each institution. Here, professionals with experience in the area offer advice on how to tackle such facilities and receive top marks in regard to electrical, power, and lighting.
Power factors, harmonics, fluctuations, and outages examined.
Defining these systems by scale and function will help us navigate their interrelation and set a basis for how we can apply them.
