Ever wondered which arc flash study recommendations are legal requirements versus nice-to-haves? In this episode, we break down everything you need to know about NFPA 70E compliance — from labeling three-phase equipment and reducing hazards through breaker adjustments, to the three core power system studies (short circuit, coordination, and arc flash). We also cover why keeping your studies current is critical, how to avoid the costly five-year scramble, and why updating your one-lines as you go is the cheapest path to staying OSHA- and insurance-compliant.
