2012 Edition of the National Electricity Safety Code available

Among the changes for the NESC's 2012 edition include standards to help design, install, operate, and maintain electrical supply and communication lines and associated equipment.


IEEE announced the availability of the National Electrical Safety Code (NESC) – 2012 Edition. The NESC provides practical guidance to help safeguard employees and the public when electrical supply and communications lines are installed operated and maintained, including overhead and underground electrical supply lines, telephone or cable and TV lines, and signal and power installations for railroads.

Some of the revisions in the NESC 2012 edition include:

  • Scope, application and definition rules extensively revised to provide clarification improvements, particularly with respect to whether the NESC or the National Electrical Code (NEC) (NFPA 70) applies in certain situations;
  • Grounding rules added specificity to the methods to be used to help achieve effective grounding connections;
  • Electrical supply stations rules added options for improved protection of energized parts from interference by activities outside the stations and for guarding inside the stations. The overhead general rules revised requirements for inspections and for facilities to be grounded or insulated;
  • Underground rules revised the inspection rules and clarified requirements for direct-buried cables and conduits not part of a conduit system;
  • Work rules added options for determining appropriate arc ratings for apparel to be worn while working on energized lines, including a new Section on Clothing requirements for <1000 Volts and added maximum clearing times allowed for specified apparel arc ratings, and;
  • Revised the minimum approach distances (MADs) to meet the requirements of IEEE 516-2009, and revised specification for the location of employee protective grounds.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
