NFPA 257

NFPA has issued the following errata on NFPA 257Standard on Fire Test for Window and Glass Block Assemblies:

  • NFPA 257, Errata 257-17-1, referencing 1.3 of the 2017 edition, issued on January 17, 2017 

An errata is a correction issued to an NFPA Standard, published in NFPA News, Codes Online, and included in any further distribution of the document.

The following three proposed Tentative Interim Amendments (TIAs) for NFPA 70E, Standard for Electrical Safety in the Workplace®, NFPA 1582, Standard on Comprehensive Occupational Medical Program for Fire Departments, and NFPA 1931, Standard for Manufacturer's Design of Fire Department Ground Ladders, are being published for public review and comment:

Anyone may submit a comment on these proposed TIAs by the March 23, 2017 closing date. Along with your comment, please identify the number of the TIA and forward to the Secretary, Standards Council by the closing date.

The National Electric Code (NEC) has provisions for protecting residential fixed building wiring by use of devices such as the overcurrent circuit breaker and the arc fault circuit. 

 

However, interest has been growing in recent years to investigate and clarify the degree to which the feeder and branch circuit load design requirements in the NEC need to be adjusted based on the increasing pace of technological innovation along the entire span of the electrical power chain.

 

There are multiple factors driving this issue and supporting the need to address this topic. For example, today’s Energy Codes are driving down the electrical load presented by end use equipment and thus load growth assumptions that justify “spare capacity” should be re-examined. In addition, larger than necessary transformers that supply power to feeder and branch circuits expose unnecessary flash hazard to electricians working on live equipment.

 

A newly published Research Foundation report summarizes a Phase I effort to develop a data collection plan to provide statistically significant load data for a variety of occupancy and loading types to provide a technical basis for considering revisions to the feeder and branch circuit design requirements in the NEC. This initial effort has an emphasis on general commercial (office) occupancies, and the deliverables provide a review of the literature, and clarify the key elements of a data collection plan in support of a potential second phase (not included in the scope of this effort).
