What is UL 67?

UL 67 is a standard that defines the requirements for panelboards used in electrical power distribution systems. Panelboards are important components in electrical installations as they house circuit breakers, fuses, and other devices that protect circuits from overloads and short circuits.

The Purpose of UL 67

The primary purpose of UL 67 is to ensure safety in electrical power distribution systems. It sets guidelines for the design, construction, and performance of panelboards to minimize the risk of electrical accidents such as fires, electrocution, and property damage. Compliance with UL 67 helps manufacturers, designers, and installers meet safety regulations and provide reliable and safe electrical systems.

Requirements of UL 67

UL 67 lays down specific requirements for various aspects of panelboards. This includes material specifications, electrical and mechanical performances, markings and labeling, durability under different environmental conditions, and clearances required for access and maintenance. The standard also covers tests and inspections that panelboards must undergo to ensure compliance.

Benefits of Using UL 67 Compliant Panelboards

Using panelboards that comply with UL 67 offers several benefits. Firstly, it enhances safety by providing reliable protection against electrical faults, minimizing the risk of accidents or damage to equipment. Secondly, UL 67 compliant panelboards have been tested and certified by accredited third-party testing laboratories, assuring their quality and adherence to industry standards. Lastly, using UL 67 panelboards can help users fulfill insurance requirements and meet code regulations, making it easier to obtain permits for electrical installations.
