The 2014 National Electrical Code (NEC) saw several significant changes that impacted the way electrical systems are designed, installed, and maintained. Here are some key analysis of changes that were made in the 2014 NEC:

1. Arc Fault Circuit Interrupters (AFCIs): The 2014 NEC expanded the requirements for AFCIs to include all 15- and 20-ampere branch circuits supplying outlets in bedrooms. This change was made to improve the safety of residential electrical systems by detecting and preventing arc faults that can lead to fires.

2. Ground Fault Circuit Interrupters (GFCIs): The 2014 NEC also expanded the requirements for GFCIs to include all 125-volt, single-phase, 15- and 20-ampere receptacles in bathrooms, kitchens, basements, garages, and outdoors. This change was made to enhance electrical safety in areas where water is present.

3. Tamper-Resistant Receptacles: Another significant change in the 2014 NEC was the requirement for tamper-resistant receptacles in all areas of a dwelling unit. This change was made to prevent children from inserting objects into receptacles and potentially causing electrical shocks or fires.

4. Surge Protection: The 2014 NEC introduced new requirements for surge protection devices (SPDs) to be installed on service equipment in certain dwellings. This change was made to protect electrical systems and equipment from power surges caused by lightning or other external factors.

5. Energy Efficiency: The 2014 NEC included new requirements for energy-efficient lighting systems, such as the use of occupancy sensors and daylight harvesting controls. These changes were made to promote the use of energy-efficient technologies and reduce electricity consumption in buildings.

Overall, the changes made in the 2014 NEC were aimed at improving the safety, reliability, and efficiency of electrical systems in residential and commercial buildings. By staying up-to-date with the latest code requirements, electrical professionals can ensure that their installations meet the highest standards of safety and performance.
