Journeyman secrets from that Electrician U video - newbies take notes

Hey all, stumbled on this YouTube vid from Dustin Stelzer breaking down journeyman electrician secrets you won't learn in school, and damn it's spot on for us apprentices. Been in the Chicago area my whole career, pulling wires on these old houses with knob and tube still lurking, and he talks about sizing feeders for subpanels using NEC 215.2 that I totally glossed over in training. Also hits on troubleshooting AFCI breakers that nuisance trip on everything from vacuums to LED lights, which is my daily hell. If you're green like me, watch it - saved me from frying a 14/2 Romex run last week. Someone in Electricians Network was raving about his tips too. OP here, RoofRat123.

Man, I felt that AFCI part in my soul, been chasing ghosts on those breakers all summer.

Those Electricians Network guys are always hyping influencers but half the advice is BS from PE-owned shops pushing volume over quality. We're getting screwed by these roll-ups undercutting on panel upgrades while we follow code.

NGL, that video had me cracking up at the part about apprentices forgetting torque specs on lugs. Tighten wrong and you're looking at a hot busbar.

Frustrated as hell with these old Chicago installs, knob and tube mixed with aluminum wiring everywhere. Last job I pulled out a whole attic full of fire hazards, boss made me redo it twice.

Warning: don't skip the torque wrench on those Square D QO breakers, saw a guy melt a panel last year ignoring it. Cost the company 5k in damages.

PSA, always separate neutrals and grounds in subpanels per that other Electrician U tip, or you'll be back fixing code violations before inspection.

Listen to the man on feeder sizing, undersize once and you're pulling new 2/0 copper for a 200A service. Don't learn it the hard way like I did on a resi rewire.
