Hospital grade receptacles are only required in a "Category 2 Space" [517.18(B)(2)]. A dental or chiropractic space is NOT a Category 2 space [See Article 100]; an optometry space doesn't fall within the scope of Article 517. [517.10(B)(d)(3)]. As for me and my house, I will serve the Lord [Joshua 24:15]. #mikeholt #electricaltraining #electrician #electricaleducation #electricaltrade #necrequirements | Mike Holt Enterprises

Receptacles for Electric Vehicle (EV) charging must be GFCI protected in accordance with 625.54. If the instructions of the EV equipment specify that it's not to be GFCI protected, then you need to 'hard-wire' the EV charging equipment. Note: There are some that feel 210.8(F) requires hard-wire EV charging equipment located outdoors of dwellings to be GFCI protected. This is beyond the scope of this post. The 2026 NEC will clarify that 210.8(F) does not apply to EV charging equipment outlets. #m

Isolated Ground Receptacles. The grounding terminal of an isolated ground receptacle must be connected to an insulated equipment grounding conductor [250.146(D). In most cases, an isolated ground receptacle is a waste of money. IEEE 1100, Powering and Grounding Electronic Equipment (Emerald Book) section 8.5.3.2 states, “The results from the use of the isolated ground method range from no observable effects, the desired effects, or worse noise conditions than when standard equipment bonding conf

There is no definitive answer about GFCI protection on hardwired EV chargers outside dwelling units. The decision will have to be made by the inspector. See 90.4, 110.3(B), 210.8(F), and 625.54. | Mike Holt Enterprises

Perhaps one of the most interesting changes in the 2023 National Electrical Code is the addition of section 110.17 which requires that servicing and maintenance of equipment must be performed by qualified personnel. This new rule has an informational note referencing NFPA 70B “Recommended Practice for Electrical Equipment Maintenance” to guide Code users on the standard related to preventative maintenance for electrical equipment.

Are island receptacles legal on the side where you are ? Here they are still allowing them to be installed on the side. Eventually they will adopt the new 2023 code and change everything but until then we are still doing it. Big change traveling here to work compared to California. #electrician #fyp #foryoupage #debate #code @Milwaukee Tool
