UL 98: The Standard for Enclosed and Dead-Front Switches

UL 98 is a standard published by UL that outlines the requirements for enclosure and dead-front switches used in electrical equipment. This standard is specifically designed to ensure the safety of workers who may come into contact with electrical equipment, as well as those who may be affected by electrical equipment failure or malfunction.

The scope of UL 98 includes:

* Enclosure types: Different types of enclosures, such as metal, plastic, or combinations of materials, can be used for electrical equipment.

* Dead-front switches: These are switches that are located within the enclosure of the electrical equipment, and are designed to provide a physical switch to disconnect the equipment from the power supply.

* Electrical equipment: This includes a wide range of equipment, including transformers, generators, and switchboards.

* Wiring: The standard covers the wiring requirements for both the enclosure and the dead-front switch.
