What is UL 698?

UL 698 is a set of standards developed by Underwriters Laboratories (UL) for use in industrial machinery wiring. This standard is specifically designed to ensure the safety and reliability of the wiring used in heavy-duty applications, where factors such as high temperature, chemical exposure, and mechanical stress can pose significant risks. The UL 698 standard helps manufacturers produce wiring that can withstand these harsh conditions and operate safely and reliably.

Key Requirements of UL 698

To ensure the safety and reliability of the wiring used in industrial machinery, the UL 698 standard has key requirements that manufacturers must meet. These requirements include:

Electrical Conductivity: The wiring must be made of a material that has a high electrical conductivity, which helps to prevent electrical currents from flowing through the wiring and increasing the risk of a fire.

insulation: The wiring must be insulated to prevent electrical currents from flowing through the wiring and increasing the risk of a fire. The insulation must also be able to withstand the environmental conditions of the application, such as high temperature, low temperature, and exposure to various chemicals.

Ground: The wiring must be grounded to prevent electrical currents from flowing through the wiring and increasing the risk of a fire. The grounding must be performed in accordance with the requirements of the electrical code, and must be clearly labeled.

voltage: The wiring must be designed to handle the voltage levels required by the application, and must be able to withstand any voltage levels that may occur during normal operation.

Current: The wiring must be designed to handle the current requirements of the application, and must be able to withstand any current levels that may occur during normal operation.

Temperature: The wiring must be able to withstand the temperature levels required by the application, and must not be damaged by high temperatures or exposure to chemicals.

UL 698 helps manufacturers produce wiring that meets the necessary safety requirements and can withstand the harsh conditions of industrial machinery applications. By ensuring that the wiring is safe and reliable, manufacturers can help to reduce the risk of electrical hazards and improve the overall safety of their products.
