Codes & Standards
February 15, 2017 - As the global demand for energy grows, the world will need solutions to ensure supply can keep up, says Standards Council of Canada; adding to the challenge are renewable sources that are not only trying to meet new demand, but also replace our fleet of fossil fuel-derived energy generation.
January 24, 2017 - The National Electrical Manufacturers Association (NEMA) published the 2017 edition of its Electrical Standards & Products Guide (ESPG), a listing of NEMA electrical standards as well as a directory of manufacturers and their products.
November 14, 2016 - The National Electrical Manufacturers Association (NEMA) has announced revisions to ANSI C119.4 (the standard for electric connectors—connectors for use between aluminum-to-aluminum and aluminum-to-copper conductors designed for normal operation at or below 93°C and copper-to-copper conductors designed for normal operation at or below 100°C), as made by the ANSI Accredited Standards Committee C119.
October 20, 2016 - The National Electrical Manufacturers Association (NEMA) has re-released NEMA WD 7-2011 (R2016) Occupancy Motion Sensors Standard, which “promotes uniformity in the use and application of occupancy motion sensors used in lighting control systems, HVAC and other devices”.
October 3, 2016 - Members of the National Electrical Manufacturers Association (NEMA in the U.S.) Motor & Generator Section and the European Committee of Manufacturers of Electrical Machines & Power Electronics (CEMEP) say they have a “new direction for global motor efficiency standards”.
July 12, 2016 - About 600 changes were introduced in the 2015 editions of the National Model Construction Codes, now known as Codes Canada.
February 14, 2017 - Believe it or not, it’s that time of year when firms start looking ahead to the camping season and campground upgrades. Nothing much has changed in recreational vehicle parks over the past CE Code cycle, but a number of changes took place over the past 15 years to make this part of the code clearer.
January 18, 2017 - Ground fault protection (GFP) requirements in the CE Code are often misunderstood; FAQs range anywhere from the very basic to complicated engineered schemes.
December 12, 2016 - An interactive power production system operates in conjunction with—and can deliver power to—another power system, such as the utility. While this could involve a standard generator, I will focus on renewable energy systems.
November 9, 2016 - The main purpose behind matching the conductor with the correct overcurrent protection is to safeguard the downstream conductor from overload and/or short circuit. Based on that simple concept, the rating of overcurrent protective devices (OCPD) always needs to be equal to or lower than the ampacity of the protected conductor.
October 11, 2016 - CE Code Section 10 “Grounding and bonding” talks of bonding metallic systems together to the grounding conductor. This reduces the danger of electric shock and property damage by providing a low impedance path for fault current back to the source, and establishes an equipotential plane, such that the possibility of a potential difference between metal parts is minimized.
September 12, 2016 - In 2013 I published a column very similar to this one to raise awareness about the hazards with delta (ungrounded) to wye (grounded) conversions. Delta systems have become increasingly less common—many of the experts on these systems have retired and lessons learned have been forgotten.
