As we start a new year learning to live with COVID-19, EC&M’s editorial team recently reflected on the topics we published in 2021 — the 20th anniversary of 9/11, the increasing solar PV market, the top electrical design firms and contractors, Code violations, etc. We selected some of the most memorable articles (listed in random order) for readers to revisit, such as a 12-part series on the differences between grounding and bonding, arc flash myths, workers' comp issues, and tips for apprenticeships.
