GENERAL:
On the Eurodam the 11,000-volt switchboard is built out of two separate switchboards, the aft and forward switchboards, which are installed in two separate rooms connected by one interconnecting line called a bus tie.

The remote control of these two MSWB’s is handled by the ship automation system (IAS) with the direct supervision of the power management system (PMS).

FORWARD MAIN SWITCHBOARD XA/872A:
Three generators provide the supply for this switchboard (FWD MSBD).

The FWD MSBD supplies the following users:

107 Bus-tie with AFT MSBD

133 Spare main transformer FZ/003TFC

121 Propulsion transformer FZ/001TFA (portside, half motor)

131 Forward main transformer FZ/003TFA

123 Propulsion transformer FZ/001TFC (starboard, half motor)

161 Bow thruster, 1900KW YA/764A

163 Bow thruster, 1900KW YA/764C

151 AC-compressor, 1060KW YB/685A

153 AC-compressor, 1060KW YB/685C

141 Accommodation substation MFZ6 transformer, FZ/004TFF

143 Accommodation substation MFZ5 transformer, FZ/004TFB

145 Accommodation substation MFZ4 transformer, FZ/004TFD

AFT MAIN SWITCHBOARD XA/872B:
Three generators provide the supply for this switchboard (AFT MSBD).
