What Will I Learn?
Master disconnect switches, contactors, and thermal overload relays with a focused, hands-on course that takes you from three-phase fundamentals to safe, compliant motor starter installations. Learn correct wiring sequences, earthing, conductor sizing, and torque practices, then apply standards, select protection devices, coordinate short-circuit and overload settings, and follow clear lockout/tagout and commissioning procedures for reliable, trouble-free operation.

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...
