Code File
June 14, 2019 - When an authority having jurisdiction (AHJ) such as myself asks, “What is your area classification or designation?’ what are we really asking? Most people assume we are looking at a section 18 requirement for a hazardous location. There are, however, several sections in which a determination from a third party is required and, in most instances, it must be in writing.
May 10, 2019 - Rule 2-024 of the CE Code mandates that all equipment used within the scope of the Code must be approved. ‘Approved’ is a specifically defined term, requiring the certification of equipment to ensure it complies with the applicable recognized standard(s), as listed in Appendix A. One important aspect of approval requirements for equipment is correlation with the provisions of the CE Code. The approval requirement presents a challenge for high-voltage equipment that has no applicable certification standard.
April 12, 2019 - Section 64-112 of the CE Code tells us a utility interactive point of connection for a solar project must meet the requirements of the supply authority and Section 84, based on predetermined safety factors. So, even though most utilities (i.e. supply authorities) are not required to conform to Section 84, the installation must do so, as a minimum.
February 13, 2019 -  Section 4 in the CE Code discusses the selection of conductors and their ampacities. In 2018, the scope of this section’s Rule 4-000 was revised to clarify its intent. At the same time, since Section 12 covers conductor installation, some rules were relocated from Section 4 to Section 12 and vice-versa, for the sake of consistency and to support the revised scope of Section 4.
December 11, 2018 - The 2015 CE Code saw a number of changes to Section 68: Pools, Tubs, Spas. The 2018 CE Code also added a few more changes, but you might just wonder, what is really new with pools from the past few years?
November 27, 2018 - This is my third and final column about the 2018 CE Code’s Section 10 rewrite (the first two were posted online in June and August). This time, I am focusing on rules related to the grounding of separately derived systems, such as generators and transformers.
September 27, 2018 — With the rewrite of CE Code Section 10, a number of questions spring to mind. In my opinion, the most important are what is the intent of Rule 10-210 and what is it really saying?
August 22, 2018 — In my last article about CE Code 2018’s Section 10 rewrite (EBMag May 2018), I explained some of the new structures and definitions, and touched upon the requirements and changes regarding grounding a consumer’s services at a meter-mounting device.
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).
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.
