Title	Identified Wiring Discrepancy in "B" Edg
Event Description	While performing a walkdown of the 'B' emergency diesel generator remote shutdown circuitry, a wiring discrepancy was identified that could have disabled the Appendix R function of the circuitry. The wiring discrepancy could have prevented complete isolation of the 'B' emergency diesel generator breaker closure circuitry from a postulated fire in the Control Building. This configuration causes the Appendix R function of the 'B' emergency diesel generator to be inoperable. A roving firewatch has been established and a 7 day action statement has been entered in accordance with the applicable fire protection procedure. Corrective actions are being evaluated to resolve this issue. The licensee has notified the NRC Resident Inspector.
