Thomas & Betts Hosts NEC Seminar for Local Contractors, Electrical Inspectors
On May 9–10, 2017, Thomas & Betts hosted two seminars at its Memphis headquarters detailing changes in the 2011 and 2014 editions of the National Electrical Code® (NEC®). The Shelby County Code Enforcement team, as well as the National Fire Protection Association (NFPA), were involved in the creation of these seminars. Approximately 140 local electrical inspectors, as well IEC contractor members of western Tennessee and Arkansas attended, all receiving continuing education units upon completion of the class.
“We hold these seminars because of our relationship and partnerships with Shelby County,” said Thomas & Betts Director of Industry Affairs David Kendall. “There is a demand for continuing education and we are very happy to be a part of it.”
“Those attending this seminar included representatives from the design, installation, inspection, and manufacturing segments of the electrical industry," said NFPA Regional Electrical Code Specialist Jeff Sargent. “Through their collective understanding and application of the new Code requirements, these industry professionals further the electrical safety mission of the NEC to the benefit of the citizens of Tennessee.”
Sargent covered significant changes that impact the following installations:
- Electrical installations in general.
- Residential electrical installations.
- Commercial and industrial electrical installations.
- Electrical installations involving special equipment, such as photovoltaics and swimming pools.
- Electrical installations involving special occupancies, such as hazardous locations and health care facilities.
For residential installations, expanded requirements for GFCI and AFCI protection furthers shock and fire protection within homes.
For commercial and industrial, new requirements for field-marking of equipment, for disconnecting means at transformers, and for consistency of what constitutes a lockable disconnecting means have been added. These requirements promote safe work practices by electricians and facility maintenance personnel.
New requirements have been added for specific occupancies, such as an increase in the minimum number of receptacles required in patient and operating rooms of hospitals. Additionally, requirements have been added for specific equipment, such as rooftop photovoltaic (PV). A new rule for rapid shutdown of conductors associated with rooftop PV systems helps to protect first responders from electric shock.
