What is UL 1363-2007?

UL 1363-2007 is a technical standard developed by Underwriters Laboratories (UL), an independent safety certification organization, that defines the requirements for power distribution units (PDUs) used in commercial and residential settings. This standard ensures the safety and performance of PDUs, protecting both users and electrical equipment from potential hazards.

Key Requirements of UL 1363-2007

UL 1363-2007 outlines several key requirements that PDUs must meet to comply with the standard:

GFCI Protection: Ground Fault Circuit Interrupter (GFCI) protection is a crucial requirement in UL 1363-2007. It helps to detect and prevent ground faults, reducing the risk of electrical shock.

Overcurrent Protection: PDUs must be equipped with overcurrent protection devices to safeguard against excessive current flow, preventing damage to both the PDU and connected devices.

Mounting and Enclosure: The standard specifies requirements for the mechanical strength and construction of PDU enclosures, ensuring their ability to withstand physical stress and providing adequate protection for internal components.

Benefits of Complying with UL 1363-2007

Complying with UL 1363-2007 offers several benefits for both manufacturers and end-users:

Enhanced Safety: By meeting the comprehensive safety requirements of UL 1363-2007, PDUs are designed to mitigate risks associated with electrical faults, providing a safer operating environment.

Reliability and Performance: The standard's requirements for overcurrent and GFCI protection help ensure that PDUs operate reliably and perform optimally, reducing the chances of power disruptions and equipment damage.

Market Acceptance: UL certification is widely recognized and trusted by customers and regulatory authorities. Complying with UL 1363-2007 allows manufacturers to demonstrate their commitment to safety and compliance, enhancing market acceptance and credibility.


UL 1363-2007 plays a crucial role in ensuring the safety and reliability of power distribution units. By complying with this standard, manufacturers can provide users with PDUs that meet rigorous safety requirements, minimizing the risk of electrical hazards. Likewise, end-users can have peace of mind knowing that their electrical systems are protected by certified and tested PDUs. Overall, UL 1363-2007 helps create a safer and more reliable electrical infrastructure for both residential and commercial applications.
