The defect
Cummins, Inc. (Cummins) is recalling certain 2020-2022 Cummins Power Generation C500D6Re trailer-mounted generator sets (gensets). Incorrect logic in the output box door switch may cause the gensets to not shut down as intended when operated in parallel with other gensets.
The risk
The operator may be unaware that the gensets did not shut down, which could result in burns, electrical shock or arc flash, increasing the risk of injury.
