This library wasn't scraped from a database. Four working electricians wrote it, each on the parts of the code they've lived — so every article carries a real hand.
Ray started pulling wire on commercial jobs at nineteen and earned his master's license in his early thirties. Three decades of service upgrades, panel swaps and sit-downs with inspectors gave him a feel for why a rule reads the way it does. He writes the way he talks on the job: blunt, calc-first, no wasted motion.
Marcus spent his career inside plants and refineries where a loose termination or the wrong fitting in a classified area isn't a callback — it's a fire. That environment made him methodical: label everything, torque to spec, verify twice. He explains rules the way he'd brief a crew before a shutdown.
Priya works in people's homes, which means she explains the code to homeowners as often as she follows it. Years of remodels — opening walls to find what the last person did — taught her that most rules are just someone's bad day written down. She trains apprentices and writes to be understood.
Luis came up during the solar and EV boom, so the newest articles are the ones he lived first-hand — rapid shutdown, battery commissioning, load management. He grew up speaking Spanish on jobsites and writes the crew's most natural Spanish. He's the one asking what the next code cycle will have to cover.
