Hello Members,

We have an audio amplifier being evaluated by a local NRTL to UL 62368-1 3^rd Edition.

The NRTL is calling out all the low voltage connectors on the rear panel on the Critical Components list.

For example the XLR and TRS connectors.

  * Can someone please let me know where this requirement could be
    coming from?

Traditionally only connectors associated with AC voltages have been called out on the CCL.

The NRTL will not allow us to use these low voltage connectors if the part is not UL Recognized.

Is there something in UL 62368-1 3^rd Edition that requires UR for low voltage connectors?

Appreciate any comments.

Sincerely,

Ryan Jazz
