2027 NFPA 70E Arc Flash Training for
Michigan’s Automotive Assembly Plants

Michigan checks both boxes most states split: journeyman and master electricians and electrical contractors are licensed statewide through LARA, and workplace safety is enforced by the state itself under MIOSHA rather than federal OSHA. MIOSHA runs its own general-industry electrical safety standards and its own inspection priorities — an out-of-state program built purely on the federal citations can miss how Michigan actually enforces.

The practical documentation ask is the same, though: the license proves the trade, the employer’s training record proves the safety qualification, and MIOSHA inspectors ask for the record.

DTE Energy carries the southeast and Consumers Energy most of the rest of the Lower Peninsula, with smaller utilities and co-ops across the UP. The exposure is concentrated where the state’s identity is: automotive assembly and stamping across metro Detroit and the I-75/I-96 corridors, the battery and EV investments around Lansing and beyond, the Grand Rapids manufacturing base, and mining in the Upper Peninsula.

Auto plants train to the production calendar — and the production calendar has two famous gaps: the summer changeover weeks and the year-end holiday shutdown, when maintenance electricians are on site but the lines are not running.
