Free, no-nonsense lessons on motor control, relay logic, PLCs, and troubleshooting — taught by a working journeyman, then practiced in an interactive wiring sandbox you can build in right now.
From reading a ladder diagram to forward/reverse, PLCs, VFDs, and troubleshooting — each in plain language with clear diagrams.
Step-by-step panel builds — motor starters, forward/reverse, PLC stations — with parts lists and wiring diagrams from first wire to final test.
Build real control circuits, wire them up, energize them, and watch them work. Inject faults and troubleshoot with a virtual meter.
Every device — buttons, switches, sensors, contacts, contactors, overloads — what it is, how it behaves, and where it's used.
Study how to navigate the code book, drill practice questions by topic, then sit a timed mock built around Utah's 2025 journeyman exam.
Live, instructor-led Zoom classes on industrial electrical and NEC exam prep — taught the WireNerd way. Coming soon; join the list for early access.
Every lesson teaches one circuit or concept clearly — then sends you to the Sandbox to build it yourself. No memorizing. Real understanding.
Ladder diagrams and the complete circuit — the foundation everything else builds on.
Start/stop, seal-in, motor starters, forward/reverse, jogging, sequencing, and timing.
What a PLC is, how its I/O works, why we use them, and how VFDs control motor speed.
Using a meter, grounding & bonding, wire sizing, schematics, and troubleshooting method.
