Practical Application of the NEC and 70E (in part)
The National Electrical Code (NEC) is an essential part of the electrical contracting business. It is the legally adopted rule book where that must be followed where construction takes place. Whether it is in the original bid documents, project management, or change orders, properly applying the NEC can make all the difference. Often significant NEC requirements are encountered after the fact with significant expense. This class provides attendees with a high-level look overvoltage protection requirements and electric vehicle supply equipment (EVSE). Also included in this class is essential requirements for performing shock and arc-flash risk assessments and documenting these assessments. This is also a new component included in subscriptions for the NECA Safety Meeting App.
The NEC provides general requirements for overvoltage protection including surge protective devices (SPDs) and Surge arresters. Article 242 of the NEC is new in the 2020 edition and resulted from combining former articles 280 and 285. This portion of the class reviews how surge protective devices work as compared to surge arresters, the general requirements of the Code that must be applied, and specific mandatory NEC requirements for installing surge protective devices beyond the option to do so.
Electric Vehicle Charging Essentials
Electric vehicle ownership is on the rise. What was an out of reach expense for many has evolved into an essential part of family and business economic plans. Constructing a capable electric vehicle charging infrastructure is front and center as tremendous opportunities for electrical contractors and the industry. This session provides the essential elements of electrical vehicle supply equipment (EVSE) installation consistent with achieving safe, sound, and successful growth of the EV market. The various types of EVSE will be explained in detail. It reviews essential requirements for contractor site assessments to ensure system capacity of electrical power sources and service equipment in addition to safe installation of EVSE branch circuits and feeders. A review of NEC rules that must be applied to EVSE installations is provided along with the responsibilities of electrical contractors and installers performing EVSE installation. NECA 413 Standard for Installing and Maintaining Electric Vehicle Supply Equipment (EVSE) will be provided.
NFPA 70E Shock and Arc-Flash Risk Assessments
NFPA 70E Standard for Electrical Safety in the Workplace addresses three electrical hazards; shock, arc flash and arc blast. NFPA 70E also requires shock risk and arc-flash and arc-blast risk assessments to be performed. This information is needed when making determinations about related to performing justified energized work. Risk assessments utilize the hierarchy of risk controls and application of processes that assist in determination of required levels of personal protective equipment (PPE). Risk assessment processes must also include evaluation of and assessment of human error possibilities. The requirement to perform risk assessments are clear, yet the standard does not provide specific and direct guidance and direction about how to accomplish it. This new session takes a detailed look at this process and provides the practical and essential elements of performing required risk assessments and attaining compliance with NFPA 70E. The new NECA Guide to Shock and Arc Flash Risk Assessment will be provided.
