🔍 Key Concepts

• Trace how power can flow from the ship service diesel generators (SSDGs) and from the emergency diesel generator (EDG) through their respective switchboards • Look for any bus-tie breakers and note their symbols and locations between the main switchboard and the emergency switchboard • Identify where shore power connects and which buses and loads it is able to feed

💭 Think About

• From the one‑line diagram, can the emergency switchboard ever be electrically paralleled with the main switchboard, or are the breakers arranged so only one source feeds the emergency bus at a time? • When the ship is in port on shore power, follow the lines from the shore connection: which buses and load panels can clearly be energized? • Compare the breaker/feeder arrangement for the emergency generator versus the normal 480‑V buses: does any line show a direct connection from the EDG to the main 480‑V bus without going through the emergency switchboard?

✅ Before You Answer

• Verify exactly which breaker is labeled as the main‑emergency bus‑tie and see what it connects between • Check whether the EDG breaker and the bus‑tie breaker appear to be mechanically or electrically interlocked (look for shared/interlocking symbols) so they cannot be closed together • Confirm from the drawing whether shore power lands on the main switchboard, the emergency switchboard, or both, and then see what loads those buses feed
