- UL50: Enclosures for Electrical Equipment. Covers the enclosure (cabinet) only, and not its contents (the actual electrical components).
- UL508a: Industrial Control Panels. Covers control panels for general industrial use, not applicable to temporary generator power connections.
- UL891: Dead-Front Switchboards. Covers switchboards, which must also include means of overcurrent protection and disconnect.
