Every week we get the same kinds of questions from homeowners, apprentices, project managers and business owners. How do I read these drawings? Is it safe to touch my panel? How do I keep a job profitable? Can AI actually help with my work? We answer them one at a time on job sites and over the phone, and we decided it was time to answer them for more people at once. So we built online courses.
The courses come from the work we do. CL Electric is a licensed C-10 electrical contractor, and our owner, Christian Correia Lopes, is also an electrical engineer with semiconductor fab experience. That mix of hands-on field work and engineering training shapes how we teach: plain language, real examples, and no hand-waving.
