June 20, 2018 — One of the major changes in CE Code 2018 is a revised Section 10 “Grounding and bonding”. This Section has been misunderstood by many in the past, with some of its requirements considered controversial and confusing.
May 10, 2018 — Grounding around high voltage is very important; we ground not only for touch and step potentials, but to ensure equipotentiality within the installation.
April 4, 2018 — Continuing our discussion regarding electric vehicle supply equipment (EVSE a.k.a. EV chargers), let’s look at a few examples to understand the load impact on the service size for a typical house, and how changes in the 2018 CE Code facilitate such installations.
February 26, 2018 — What is a separately derived system and why is it important for Section 10? To fully understand, we need to look at how we define derived as it is used throughout the CE Code, as it has many synonyms and definitions.
February 13, 2018 – With the steady increase of electric vehicles on our roads, the 2018 CE Code (publishing this month) includes new Rules that recognize EV energy management systems (EVEMS), which address evolving EV technology and issues associated with future loading on electrical infrastructure.
January 22, 2018 — The number of changes coming to the 2018 CE Code are fairly substantial, and while a number of them involve tweaked wording and/or definitions, there are also a fair number of what I would call “significant” changes.
October 6, 2017 — Rules in Section 16 (New 16-300 series added) of the upcoming CE Code 2018 have been amended to include requirements for Class 2 power and datacom circuits. Although the new requirements do not reference “Power-over-Ethernet” (PoE) terminology, an Appendix B Note is added to explain the “Class 2 power and data communication circuit” is based on the concept known as PoE, introduced by the IEEE 802.3 series of standards.
September 15, 2017 — In addition to a number of changes in 2012, CE Code Section 62 “Fixed electric heating systems” underwent a fairly substantial rewrite in 2015. So what’s changed?
August 17, 2017 - The new CE Code (24th ed.) is almost here, and Section 64 contains several important changes (already approved by the CE Code-Part I Committee), two of which I will discuss here.
June 28, 2017 - What do circuit loading and demand factors mean, and how are they different? A circuit load is a component or portion of the circuit that consumes power. A demand factor is a time-dependent fractional quantity that will always be less than, or equal to, one. Huh?
May 26, 2017 - Required by the National Building Code (NBC), smoke alarms must be permanently connected to a lighting circuit, or one that supplies both lighting and receptacles, so as to quickly detect when there’s a problem with the circuit.
April 10, 2017 - The 3rd Memorandum of Revision (MOR) is out, and Rule 8-104 is undergoing some significant changes. Subrule (8) has been deleted from the CE Code, and 8-104(5) and (6) have been rewritten. What does this mean for calculating cable sizes used in direct burial installations?
March 14, 2017 - As the name suggests, energy storage systems (ESSs) are mechanisms capable of storing energy for use at a future time.
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.
