EV charging stations, “Charge Points” (after the ChargePoint brand), “Level 1/2/3” Chargers, Superchargers, DC Fast Chargers, CCS Combo Systems, and SAE J1772 Connectors, all refer to Electric Vehicle Supply Equipment or EVSE.
The rise of Power Over Ethernet (PoE) technologies and ever-evolving power delivery capabilities have transformed the building environment inside and out over the last two decades.
Electrical equipment intended for potentially explosive atmospheres (or hazardous locations), is evaluated to stringent requirements in accordance with the NEC, local regulations, and/or harmonized standards such as the IEC 60079 series standards.
Electric vehicle batteries that are repurposed for use in new applications generally undertake a three-step process.
The 2020 edition of the National Electric Code (NEC) includes special provisions for reconditioned or refurbished electrical equipment, defined as “electromechanical systems, equipment, apparatus, or components” that have been reworked and restored to operating conditions.
What is the rating of a branch circuit, feeder, or consumer’s service as mandated by the Canadian Electrical Code?
Codes and standards exist to ensure the safety of the public. While the goals behind the requirements are the same, sometimes, they are not harmonized with each other despite our best efforts.
Health and safety considerations are now an integral part of machine design operations; therefore, manufacturers, project managers, and inspectors need to be aware of critical functional safety (FS) design requirements.
AHJs are the acute eyes in the field to identify products that appear to be non-conforming or potentially dangerous to the community. They are a vital resource to Nationally Recognized Testing Laboratories (NRTLs) in keeping our communities as safe as possible.
Field evaluations offer the electrical industry an opportunity to quickly solve problems with unlabeled equipment in the field. With an understanding of how they are properly executed and good communication between all parties involved, the AHJ and the field evaluation body can work together to promptly address compliance issues in the field.
