This is the generator-side coil; the utility coil is installed on the side of the compatible mechanism. Inspect the associated 084464 limit switches and control circuit when diagnosing a failed or shorted coil. Replace additional components only when testing confirms damage or when required by the applicable service procedure.

Transfer switches contain potentially lethal utility and generator voltage. Installation and testing should be performed by a qualified technician after every power source has been isolated.

Verify the transfer-switch model, serial number, amperage, coil position, and original part number before ordering.
