Industrial Control Panel Standard UL 508A Training

Get to know the critical compliance requirements of UL 508A safety standard

UL 508A is a standard for the construction of industrial control panels, offering guidelines to panel builders on  proper component selection, grounding, wiring methods and cable routing.

UL 508A provides a third party inspection authority to provide the customer with proof the assembled industrial control panel meets electrical safety standards and in compliance with the national electrical code.

Course objective

  • Compliance with UL 508 includes 
  • Is required to maintain Ul certifications during inspection and audits.
  • Assures your customer that your product is built with a high level of electric security.
  • Allow your panels to be UL Marked as a complete appliance.
  • Gain Competitive advantage with UL 508A compliance product.
  • Our ul508a panel design fundamental training covers the standard requirement and demonstrates how we help you to be compliant.
