What is UL 1390?

UL 1390 is a widely recognized standard for evaluating the safety of electrical signs and luminous discharge tubes. It provides guidelines for manufacturers to ensure their products meet the necessary safety requirements. In this article, we will explore the key aspects of UL 1390 and its importance in the industry.

Definition and Scope

UL 1390 specifically addresses the safety standards for electrical signs and specifies the requirements for their construction, installation, and operation. The scope of this standard includes both outdoor and indoor electric signs, which are designed to display advertising, information, or other visual communication.

Key Requirements

UL 1390 outlines several key requirements that manufacturers must adhere to. First and foremost, it mandates that electrical signs must be constructed with materials that meet proper electrical insulation and fire resistance standards. This ensures that the signs can operate safely without posing any risks to individuals or property.

Additionally, the standard requires proper grounding and bonding of electrical components to prevent electric shock hazards. It also sets criteria for clearances, wiring, and ventilation to avoid overheating or fires. Installation instructions and labels should accompany these signs to ensure correct and safe assembly, use, and maintenance.

Benefits and Compliance

Complying with UL 1390 offers several advantages for manufacturers. Firstly, it helps enhance the overall safety and reliability of electrical signs, which ultimately protects both consumers and businesses. By meeting the standard, manufacturers also demonstrate their commitment to quality and compliance, making their products more trustworthy in the market.

Furthermore, compliance with UL 1390 allows manufacturers to obtain proper certification and labeling for their products. This certification serves as proof that the manufacturer has followed all necessary safety measures, making it easier for their products to meet regulatory requirements and gain market access.
