Industrial electrician
An 8-step path to becoming an industrial electrician: electrical safety and lockout-tagout, reading drawings, three-phase power and motors, star-delta starters, VFDs, basic PLCs, distribution boards and factory maintenance. You can then work in industrial parks, factories or M&E contractors. Suits disciplined, logical people.
