9/27/20105Failure FactsAn arc flash incident is always the result of at least one of the five change of states.OEMs did not generally design switchgear to allow for survivability of human operators when performing switchgear related tasks. Regulations and standards are typically developed as a result of tragic incidents and are often written in blood.

9/27/20106Regulations and StandardsOSHA 29 CFR 1910 OSHA is the enforcer Now recognized arc-flash as a work place hazardNFPA 70E 2009 The how to standard. Provides guidance on specific steps that must be taken to comply with the more general OSHA standards. This regulation specified that arc-flash study must be completed by Jan. 1, 2009Other significant design codes and standards:IEEE 1584 Provides steps required to perform calculation of incident energy from which decisions about appropriate PPE are made. Takes into account the role of the over current protective device.ANSI/NFPA 70-2002National Electric CodeNESC

Recommended Requirements for Remote Racking Systems ContSystem Must Be easy to operate and account for the Human Factor.Be modular and portable. Be adaptive to old and new breaker designs.System MustNot modify original breaker controls or wiring. Give positive indication of breaker status and position. Standardize the way a breaker is rackedMonitor tilt angle of vertically racked breakers
