AC Circuit Breaker Panels

For AC circuit protection and distribution, the system will normally employ a minimum of two AC panels. One AC panel will be the AC main distribution Panel (ACP). The ACP will enable the desired AC source – generator feed(s) and/or shore power feed(s) - to be selected and directed to the vessel’s AC Sub-panel(s) (ACS). The standard AC Sub-panels will house up to eighteen (18) Hydraulic-Magnetic Circuit Breakers and are approximately 14”wide x 20”high x 5”deep.

Both the AC main distribution Panel and the AC Sub-panels may be configured for single phase or three phase operation (Note: smaller AC sub-panels to be introduced). When the AC Sub-panels are configured for single phase operation, each ACS may have a double pole main circuit breaker to enable power shutoff to all remaining sixteen (16) poles within the panel. When the standard AC Sub-panels are configured for three phase operation, each standard ACS may have a three pole main circuit breaker to enable power shutoff to all fifteen (15) remaining poles within the panel. (Note These remaining 16 poles in the single phase panel may be populated with a combination of single and double pole circuit breakers, while the 15 poles remaining in the three phase panel may be populated with a combination of single pole or double pole single phase circuit breakers, and three pole three phase circuit breakers.)

The ACP will:

• Have a 6.5” touch screen control panel providing:
1. Voltage, frequency, and amperage for each power source
2. Voltage and amperage for each individual line out feed
3. Total amperage being consumed
4. Complete access to system monitoring and control
NOTE: all above display data will also be available at every MCS touch screen panel throughout the vessel
• Enable selection of the desired AC power source for each feed line
• Provide circuit protection for each AC source and each line feed directed to AC Sub Panels (Note: one or more ACS may be fed from any individual line feed)
• House manually operated hydraulic magnetic AC circuit breakers and power source selector switches.
• Accept location within the engine room or other non-air conditioned environments, as the magnetic-hydraulic circuit breaker stable operating temperature range is –40° to +85° Centigrade (-40° to +185° Fahrenheit).
