TARGET GROUP: electrical department of machinery manufacturers

SCOPE: The aim of the course is the design of Electrical Control panels of machinery, in compliance with both the USA and the Canadian Technical Standards. Hereafter the three standards we will discuss during the training:

  • UL 508A: The standard for the design, construction and certification of Industrial Control Panels of machinery in USA. We are member of the Standard Technical Panel.
  • NFPA 79: inspired by EN 60204-1 and which deals with the construction of the switchboard and especially the characteristics of the  machine’s control panels. GT Engineering participates in the working group of the new edition that will see the light in 2024.
  • C 22.2 N°286: Since Janualy 2022 it is the reference standard for Industrial Control Panels to be imported into Canada.

CONTENT: Professional training on US and Canadian regulations for electrical panels of machinery.
