Deep dive into motor starters, contactors, and overload relays for industrial applications. Covers NEMA vs IEC contactors, selection criteria, overload class selection, arc suppression, and troubleshooting contactor failures.
Plant electricians lose time when they treat every bucket the same. Motor Starters, Contactors & Overload Relays is the method for this class of problem: control power first, then power circuit, then the machine. A chattering coil, a wet winding, and a bound pump look similar on a hurried radio call. They do not look similar on a meter.
A chattering starter is a coil, an overlay, or voltage. It is not automatically a welded contact. Check coil voltage under load, the seal-in, a loose control transformer, and the heater class before you condemn the bucket.

Industrial electricians and techs who live in MCCs, VFDs, and motor leads — not residential work, not HVAC capacitor jobs.
Who it is not for: license mills, VR demos, or anyone looking for a fake testimonial. We do not invent customer quotes. Certificates of completion after quizzes go in the file. They are not a journeyman card, an ISA credential, or NFPA 70E qualification by themselves.
ForgeLine Academy currently lists 78 industrial maintenance courses. 44 of those are free (Mechanical and Electrical). Premium unlocks I&E (18) and Engineering (16). That is the whole catalog — not a 22-course teaser and not a four-hour overview of the plant. Call +1 580 421 5714 or email support@forgelineacademy.com for plant cohorts and on-site classes.
Motor Starters, Contactors & Overload Relays is one course in that 78-course ladder. Mechanical and Electrical remain free. I&E and Engineering are premium. On-site and plant cohorts are scheduled through on-site training or plant support.
Training is educational. It does not replace your site's lockout/tagout, permits, PPE, or required licenses. Certificates of completion go in the file. They are not a license.
