⚡ Start Here — House Rules & How This Place Works
Welcome aboard. Quick read, then go dig into the classroom and community. Introduce yourself. Drop a comment below: where you're at in the trade, what you're working toward, and what you're worst at. That last one's the important one — it tells me what to build next. How levels work Courses unlock as you level up. Level 1 is first-year material, Level 2 second-year, on through Level 5. Levels 6 through 9 hold the specialty courses. You level up by showing up — posting, asking questions, answering them, helping the guy a year behind you. That's by design. The classroom is only half of what you're here for. The other half is the other tradesmen in this room. House Rules: 💡 No soliciting. No promoting your business, your course, your channel, or affiliate links. Not in posts, not in comments, not in DMs to members. This one gets you removed. 💡 Ask the question. Nobody here got good by pretending they already knew. There's no such thing as a dumb question in this room. 💡 Answer when you can. The best answers here come from members, not me. If you know it, share it. 💡 Keep it professional. Argue code all day — that's how we all get sharper. Don't make it personal. 💡 Safety first. No advice that puts a person on the wrong end of an arc flash. Cite your section when it matters. Code varies. We work off the NEC, but your AHJ and adopted code year are what govern your job. Verify locally before you pull wire. What's Coming: I'm building this out one module at a time — theory, AC vs. DC, conduit bending, motors and motor controls, and more. Watch for polls. What you vote on is what I build. Glad you're here. Let's get to work. ⚡

⚡ Trade Question of the Day — Same Wire, Twice the Distance? ⚡
You’re comparing two copper conductors. Both have the same wire size and are at the same temperature, but one is 50 feet long and the other is 100 feet long. How does the resistance of the 100-foot conductor compare with the 50-foot conductor? A. Half as much resistance. B. The same resistance. C. Twice as much resistance. D. Four times as much resistance. 👇 What’s your answer—and why? Bonus: Why might conductor length matter when supplying equipment a long distance from the panel? Answer and explanation tomorrow! ⚡
