In the construction industry, one of the important objectives of contractors and the construction team—aside from being paid for the job—is attaining National Electrical Code (NEC) compliance and final approval. In the electrical field, some key factors relate to achieving this ultimate goal.
Adoption and use of the 2014 National Electrical Code (NEC) is underway in many areas of the country. Adoption processes and timelines can vary between states and jurisdictions. With the 2014 NEC, a few additional requirements apply to emergency systems.
Special rules for ground-fault protection of equipment (GFPE) apply to healthcare facilities. Section 517.17(A) indicates that these GFPE rules apply to hospitals and other buildings (including multiple occupancy buildings) with critical-care space or where life-support equipment is used.
For many years, The National Electrical Code (NEC) has provided rules for equipment disconnects. NEC requirements are very specific for motors and motor-driven machinery, but they differ from lockout/tagout rules in NFPA 70E, Standard for Electrical Safety in the Workplace. The reason is simple.
In the electrical industry, a new method of protecting workers from arc energy is gaining popularity: prevention through design. Simply speaking, the design and installation of equipment or systems incorporates inherent safety features that protect workers from serious arc-flash injuries or death.
The development process of the 2017 National Electrical Code (NEC) has begun. In January, 19 Code-making panels (CMPs) held their “first draft” meetings to address roughly 4,000 public inputs (PIs). The NEC is primarily a reactive code that evolves through demonstrated need.
Advances in medical technology have resulted in more medical appliances and equipment being used in general-care and critical-care patient bed locations. The governing body of the healthcare facility typically determines the level of care in a given area.
The term “qualified person” has a very broad meaning in a general context. From a simple standpoint, outside of the codes and standards world, it might mean having the qualities, accomplishments, etc., that fit a person for some function, office, or the like.
A reader wrote in that an inspector had turned down one of his projects, citing the installation was in violation of National Electrical Code (NEC) 517.13(A) and (B) because Type MC cable was installed in the patient-care areas.
The 2014 National Electrical Code (NEC) has new requirements for field-applied hazard warning markings, signs and labels. Throughout the NEC, rules that required signs, labels and other markings also required a specific signal word be included in the sign, label or marking.
In a recent training presentation, a question came up about the new identification requirements for automatically controlled receptacles. Does the marking need to be on the receptacle face, or is a marking on the faceplate in compliance?
Traditional construction methods and techniques have evolved to be more efficient and cost-effective. Technology affords the construction industry the ability to model projects remotely and prefabricate many of the construction elements off-site.
