摘要

NFPA 70E is the MSDS of electricity. Hazards of electricity fall into two distinct categories, shock and arc flash. Almost intuitively, qualified electrical workers understand electrical shock hazards. Shock has been the primary concern of all electrical workers for many decades. The greatest danger of electrical shock exists when the worker assumes rather than verifies that equipment is deenergized. What tools can we provide the technician to systematically avoid that assumption? The more challenging piece of the safety process is arc-flash. Arc-flash boundary calculation and the determination of proper PPE when entering the arc-flash boundary require complex calculations which in turn, require accurate information about short-circuit current and protective device operating times.
