Train as an industrial maintenance & controls technician.
Real plant knowledge, written by people who have actually crawled inside MCCs and traced ladder logic at 2 AM. Electrical fundamentals, LOTO, motors, PLCs, instrumentation, troubleshooting — everything you need to build a $30–$60/hour career.
The full 10-module curriculum
Sequential and gated. Each lesson ends with a key-terms glossary. Each module ends with a 10-question test you must pass at 80% to unlock the next.
Electrical Fundamentals for Industrial Systems
Voltage, current, resistance, AC vs DC, three-phase power, grounding, and how the National Electrical Code shapes every industrial install.
Industrial Safety, LOTO & Arc Flash
OSHA 1910.147 lockout/tagout, NFPA 70E arc-flash boundaries, PPE categories, and the verify-zero-energy habit that keeps technicians alive.
Reading Electrical Schematics & P&IDs
Ladder logic symbols, ISA instrumentation symbols, wire-numbering conventions, and the systematic way to trace a circuit from print to panel.
Motors, Drives & Motor Control
Three-phase induction motors, across-the-line starters, soft starters, variable-frequency drives, and the practical troubleshooting that keeps lines running.
Sensors & Instrumentation
Discrete sensors (proximity, photoeye, limit), analog instruments (4-20 mA, RTD, thermocouple, pressure, flow), and how to wire and troubleshoot them.
Pneumatics & Hydraulics for Maintenance
How compressed air and oil power factory motion: valves, cylinders, FRLs, accumulators, and the most common failures you will be asked to fix.
PLC Fundamentals
How a Programmable Logic Controller scans, reads I/O, executes ladder logic, and drives the world. Allen-Bradley and Siemens basics plus how to troubleshoot live.
HMI, SCADA & Industrial Networks
How operators see and control the plant, and the Ethernet/IP, Profinet, and Modbus networks that move tags between PLCs, HMIs, and SCADA servers.
Electrical Troubleshooting Methodology
The half-split method, signal tracing, and the disciplined use of DMM, oscilloscope, and megohmmeter that separates a $30/hour tech from a $60/hour tech.
Predictive & Preventive Maintenance + Career Path
Vibration analysis, thermography, oil analysis, CMMS workflow, and the certifications and resume habits that turn this knowledge into a long industrial career.
