Countertops Located in Other than Kitchen Areas – Section 210.52(A)(2) 2017 NEC

We are all familiar with the NEC requirement to place receptacles within the first 24 inches of a kitchen countertop edge, and then locate them every 48 inches thereafter. But did you know that fixed countertops in rooms such as dens, libraries, living rooms, bedrooms and the like now have receptacle requirements, and they are different from the requirements found in 210.52(C) that apply to kitchens?

Short-Circuit Current-Rating (SCCR) VS. Available Fault Current: Understanding the Maze and What’s New for 2020

Section 408.6: A Brand-New Addition to the 2020 NEC
NEC section 408.6 states: Switchboards, Switchgear, and Panelboards shall have a short-circuit current rating (SCCR) not less than the available fault current.  In other than one- and two-family dwelling units, the available fault current and the date the calculation was performed shall be field marked on the enclosure at the point of supply. The marking shall comply with 110.21(B)(3).

Making NEC 408.6 Simple
This new Code Section simply means that electrical panels including main-breaker and main-lug type panels and switchboards & switchgear equipment must be rated (in amps) to withstand the high levels of current that will flow should a short-to-ground or other fault occur at the equipment. In ALL locations other than dwelling units, that anticipated fault current must be marked on the equipment enclosure near where the supply conductors enter in, along with the date that the calculation producing that number was performed. The new Code Section also says the markings on the equipment must comply with 110.21(B)(3). Section 110.21(B)(3) tells us that markings must be sufficiently durable to withstand the environment.

Understanding Electric Vehicle Charging – Wireless Power Transfer – Article 625

Electric vehicle (EV) charging is not new, as Article 625 was introduced to the National Electrical Code with the 1996 edition. The following year, the Toyota Prius became the first mass-produced (hybrid) electric vehicle. More followed, including Tesla, Nissan, and Chevrolet. Until recently, however, the only viable method for charging an electric or hybrid vehicle was via a direct connection to a power supply, either from premises wiring or at a charging station.

For the 2017 Code cycle, both definitions and requirements have been added to Article 625 for the purpose of regulating another type of EV charging: wireless power transfer, or wireless charging. Before we examine the Code requirements, let’s answer a couple of important questions. First, how does wireless charging work? Second, how efficient is this technology?

GFCI Protection Requirements: Mobile & Manufactured Homes 2020 NEC – 550.13(B)

The 2020 NEC now recognizes that GFCI protection for mobile and manufactured homes must be equal to that of stick-built and modular type dwellings. Construction Codes, in general, have always been less restrictive for mobile-type dwellings. This may be because mobile homes are often titled with the Motor Vehicle Department, and this type of housing is built, inspected, tested, and listed off-site at a manufacturing plant.

Conductor Derating on a Rooftop Made Easy

Derating conductors for the environment where they are installed is an important consideration for selecting the type and size of conductor for a particular installation. When installing a system on a rooftop, special consideration must be given to the ambient temperature inside the wire way or conduit that contain the conductors to prevent heating beyond the rating of the insulation of the conductors.

Conductors installed in raceways on rooftops can be subject to higher temperatures than they would be just from the heating effect of solar energy absorbed by the wall of the raceway. This effect becomes more evident when the proximity is very close to the roof or the raceway is in contact with the roof surface.

Stepping Up and Stepping Down: Using Transformers to Change Voltages to Desired Levels

Transformers are used when power voltages need to be changed, or transformed, to other levels. Sometimes voltages need to be increased when sending power long distances. Other times, voltages need to be decreased for equipment that uses the power. Regardless of whether the voltages are being stepped up or stepped down, the same process of changing windings is used to transform voltages to different levels.
