• Condition Details

This unit is being sold in used surplus condition. It was acquired from an industrial environment and has not been tested by our facility. The transfer mechanism and control assemblies appear complete based on visual inspection; however, no functional testing has been performed. The enclosure shows signs of previous use, including scratches, paint loss, surface oxidation, markings, and installation-related modifications. Conduit openings are present on the enclosure from prior installation.

Because testing has not been performed, the unit is being sold as surplus equipment and should be inspected and commissioned by a qualified electrician or generator technician prior to installation.
