UL 508A: Industrial Control Panels

Professional Training for Industrial Control Panels

TARGET GROUP: electrical development department

SCOPE: At the end of this training on UL 508A you know how to design Machinery Control Panels in compliance with both USA and Canada Electrical Standards

CONTENT: The NEC contains requirements necessary for the proper installation of electrical conductors, equipment, cables, and raceways for power, signaling, fire alarm, optical cable, and communications systems for: 

  • Public and private premises, including buildings, mobile homes, recreational vehicles, and floating buildings
  • Yards, lots, parking lots, carnivals, and industrial substations.
  • Conductors and equipment connected to the utility supply.
  • Installations used by an electric utility, such as office buildings, warehouses, garages, machine shops, recreational buildings, and other electric utility buildings that aren’t an integral part of a utility’s generating plant, substation, or control center.

In other words, the NEC, like the equivalent Canadian Electrical Code, are the reference for electrical safety in Fixed installation. Those are the base of the Standards developped for the Electrical Installation in Machineries, like UL 508A or C22.2 N°286.

Below, the main topics covered:

  • Bonding - Size of Terminal or Bonding Conductor
  • Transformer and Power Supply Secondary Grounding
  • Identification of Grounding and Grounded Circuit Conductors and Terminals
  • Enclosures and Accessibility of Live Parts
  • Ventilation Openings
  • Bonding
  • Wire Bending Space
  • Enclosure Environmental Control Devices
  • Power Circuits: Components Type, Sizing, Conductor requirements
  • Circuit breaking: Component Type, Sizing, Setting
  • Combination Motor Controller: Sizing of Motor, Heating loads and Lights
  • Feeder Circuits: Components type and Sizing
  • Power Transformers: Components type and Sizing
  • Control Circuits: Components type and sizing; Low-Voltage Limited Energy Circuits.
  • Components and Panels Marking
  • Industrial Control Panels
  • Calculation of SCCR (Short Circuit Current Rating)
