The UL official definition of an industrial control panel, “an assembly incorporating two or more pieces of industrial control equipment or related control circuit devices, provided with interconnecting wiring and terminals for connections in the field. To allow the installer to properly install the panel in accordance to National Electrical Code (NEC) and other codes, electrical ratings and instructions are to be clearly explained on the panel.”
The panel and equipment pertained inside are intended for installation in ordinary locations with an ambient temperature not to exceed 40°C (104°F). All components and the panel itself shall meet the National Electrical Code, ANSI/NFPA 70. All panel fabrication facilities meeting UL508A standards are certified by a third party inspection authority to ensure they are following the UL standards. All panels meeting these standards will carry the UL508A Mark.
While UL allows for an “enclosed type” and an “open type” panel, Engenuity Systems specifically provides enclosed panels.
Certified Enclosure Benefits
Benefits of selecting Engenuity Systems to provide your UL 508A certified enclosure include:
- The UL 508A certification ensures your control panel complies with the nationally recognized safety standards of UL and are compliant with the national and local electrical codes ensuring the utmost public safety.
- All fabrication facilities and manufacturers carrying the UL 508A certification are subject to periodic unannounced inspections of their facilities by UL personnel. This ensures the manufacturer continually meets the UL requirements for the 508A certification.
- For panels to carry a UL 508A mark, all components within the panel must also carry a UL certification ensuring they meet these global safety standards. Having all products UL certified protects the quality and integrity of the panel and encapsulates global safety standards.
General Enclosures & Cabinets
General provisions and requirements for all cabinets include:
- Protection Against Corrosion
- Support and Securement of Live Parts
- Conduit Bushings
- Insulating Barriers
- Insulating Materials
- Grounding – General
- Grounding – Size of Terminal or Bonding Conductor
- Identification of Grounding and Grounded Circuit
- Conductors and Terminals
Outdoor Enclosures & Cabinets
If your requirements are for an outdoor enclosure or cabinet, the UL 508A standard specifically outlines requirements to address these key areas to ensure each panel meets the same safety standards:
- Enclosure Openings
- Accessibility of Live Parts
- Ventilation Openings
- Enclosure Environmental Control Devices
- Field Wiring
- Internal Wiring
- Disconnect Switches
- Branch Circuit Protection
IAPMO National Standard CSA 22.2 No.14
IAPMO is a nationally recognized technical committee which has developed American National Standards (ANS) for more than 30 years. Initially, the designation was Secretariat for the ANSI Z124 Technical Committee, and since 2005 as an ANSI-accredited standards development organization with the designation of IAPMO/ANSI.
Although IAPMO’s standards have traditionally focused primarily on plumbing, they now develop national standards for solar heating systems and components. IAPMO’s national standards are developed via an open consensus process and approved by the respective standard committee.
Engenuity Systems meets the CSA 22.2 No. 14-22 which standard applies to control and protective devices, and accessory devices, rated at not more than 1500 V, for starting, stopping, regulating, controlling, or protecting electric motors, generators, heating apparatus, or other equipment used to control an industrial process that is intended to be installed and used in non-hazardous locations in accordance with the rules of the Canadian Electrical Code, Part I.
The standard ensures the safe operation of equipment up to 40ºC (105 ºF) installed in non-hazardous environments and applies to assemblies of industrial control and protective devices rated 750 V or less and includes assemblies of automatic control and process equipment.
Certain equipment intended for use with electric elevators, air- conditioning and refrigeration equipment, cranes and hoists, electronic and solid-state control equipment, and TV-rated relays, etc., can be subject to additional requirements not included in this Standard. This Standard does not apply to equipment covered by other CSA Standards, such as power supplies, programmable logic controllers, assemblies of equipment intended solely for the distribution of power, assemblies for controlling power factor, switches other than manual motor controllers, and electrical components intended to protect circuits other than motor branch circuits.
