July 27, 2018 — For the first time in the CE Code (2018 ed.), a unit substation is defined as an integrated unit consisting of one or more transformers, disconnecting means, overcorrect devices and other associated equipment, each contained in an enclosure designed and constructed to restrict access to live parts (Rule 26-240).
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 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?
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.
