![]() The issues that must be dealt with include the general environment, ventilation, exhaust, fuel, acoustical, electrical clearances, locations, installation, and removal considerations.Įnvironment. Engineers must devise practical, actionable methods to deal with the environment in which generators are installed. Typically, emergency and standby generators are not deployed in ideal environments. Examples are egress lighting, fire alarms, and fire pumps. Article 700 covers issues associated with preventing loss of life. Article 701 covers issues associated with preventing hindrance of life-saving measures-for example, firefighting, ventilation, and smoke-removal systems. Examples of optional standby systems include data centers or a commercial business resulting in discomfort, serious interruption of a process, or damage to a product. Looking at them in terms of increasing levels of importance, Article 702 is optional and usually used purely for backing up utility power, but not for life safety. This article will focus on the applicable codes, environmental and operational design constraints, and considerations for health care and mission critical facilities while offering commissioning suggestions.Īrticles 700, 701, and 702 sometimes are confused. ![]() ![]() As these standards continue to evolve, as previous design approaches are evaluated over decades of service, and as retrofit projects encounter complications, the lessons learned by the industry must be taken into consideration to ensure modern emergency systems are safe and reliable. Understand the implications of specifying generators in mission critical facilitiesĮngineers of emergency power systems must be familiar with the latest requirements of NFPA 70 -2017: National Electrical Code (NEC) and NFPA 110-2016: Standard For Emergency and Standby Power Systems. ![]() Consider various design, environmental, and commissioning aspects when designing generator systems.Know the codes and standards that dictate the specification and design of emergency and standby generators. ![]()
