DISCUSSION

Discussion item submitted by: Sam Russell, Sensata Technologies

Sam Russell requested STP member input on expanding the voltage rating of the devices covered by the scope of UL 1699B from 1000 V to 1500 V.

UL noted that if the voltage is increased, the spacing requirements would need to be revised and that UL 1741, the Standard for Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources, and UL 489B, the Outline for Molded-Case Circuit Breakers, Molded-Case Switches, and Circuit-Breaker Enclosures For Use With Photovoltaic (PV) Systems, could be referenced as examples.

STP members expressed support for this proposal and formed a Task Group to develop the necessary requirements to increase the voltage to 1500 V. See the end of this report for Task Group members.
