National Electrical Safety Code

Generally speaking, the standard of care for campus power system safety is set by both the NEC and the NESC. There are gaps, however-- the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.

“Malakoff” | Henri Rousseau (1898)

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the emergent #SmartCampus since many campus power systems are larger than publicly regulated utilities.  Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC.   They are fairly technical and subtle in their implications for the advancement of safety and sustainability in campus power distribution systems.   Some of the proposals deal with coordination with the National Electrical Code — which is now deep in its 2020 revision cycle.

Keep in mind that that NESC is revised every 5 years at the moment.  The next steps in the 2022 NESC development will span across most of the next 18 months as the various subcommittees meet to prepare written responses to public input.  A preprint of those proposals will be posted no later than July 1, 2019.  This opens the comment period, by interested parties, on the submitted change proposals and the subcommittee recommendations.   Our provisional workspace is linked below:

Comments are due March 1, 2020. 

The subcommittee that coordinates standards action between the IEEE and NFPA suite of technical standards — IEEE Standards Coordinating Committee 18 — will also be hosting worksessions in the coming months.   While those work sessions are generally closed to the public, some of the concepts will be open for discussion during any of the IEEE E&H online committee meetings which meets 4 times monthly in Europe and the Americas.  The next online meeting is shown on the top menu of the IEEE E&H website:

Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database.   Forced outages in on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute.    The database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system.   The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems; many of which are larger than publicly owned or cooperative utilities.
