In order to perform preventive maintenance on our Substation, one of our incoming National Grid feeders will be switched offline. We will be conducting switching to building feeds listed below between the hours of 5 am to 7 am. and again, later in the afternoon
once work is complete. This will cause power losses from 1 to 10 seconds while we do the switching. Emergency power circuits will see a loss similar to generator testing both in the morning and again in the afternoon. Not all areas are affected in the afternoon.
