UL 1691:2021 PDF Download

UL 1691:2021 is a standard that covers the requirements for single pole locking-type separable connectors. These connectors include attachment plugs, cord connectors, panel inlets, panel outlets, adapters, and accessories. They are rated up to a maximum of 800 amperes and up to 600 volts AC or DC. These devices are not intended for connection or disconnection under load conditions.

The standard specifies that these connectors are intended to provide power from feeders or branch circuits, and are suitable for use in various applications such as amusement parks, film and TV sets, theaters, carnivals, construction sites, and other temporary installations. However, they are not intended for use in hazardous locations.

The standard further clarifies that attachment plugs and cord connectors are designed for use with cables having copper conductors only, either in outdoor or indoor locations. Inlets and outlets, on the other hand, can be used with cables or bus bars with copper conductors. The standard does not apply to other types of plugs, receptacles, cable connectors, or devices covered by different standards.
