The system is designed to allow for silent running to a continuous power of 10kw.This is achieved by utilizing Mastervolts 24/5500 Lithium batteries together with 3 x Mass Combi Pro 24/3500 Inverter chargers.
The house bank has a usable battery capacity of 1280 amps. The system is expected to run for approximately 9 hours by battery whilst running with a load average of 3.3kw.
The engines will be fitted with 2 x 24 volts 240 Amp Alternators and Mastervolt Regulators to allow for a total recharge of 480 Amps or approximately 11kw.
This will allow the systems to be run whilst the engines are running without the need to start the generator. This is possible provided the electrical loads are within the available power output of the inverters.

The ACMI mains panel will allow the AC system to be easily managed and allow the use of a generator auto start function to be activated using programmed logic.
The system will also be able to manage loads when required for example when the load is required to be taken off the generator for use of the thruster via a PTO. The system will have touch screen control via the C-zone Touch 10 located in a common
area and touch 5 located in a technical space for diagnostics and redundancy. Systems can also be controlled via push buttons where dedicated controls are needed. All circuits can be safely manually bypassed in an emergency or fault situation.

There will be a dedicated radio / emergency battery which when activated by the emergency bypass will power communications and critical equipment via a manual switch panel. These items will be able to be controlled via a traditional style switch panel when in bypass mode and will offer simple yet reliable redundancy for critical systems.

1404 Lighting
The lighting shall be LED.

1405 Power Outlets
Power outlets will be located throughout the vessel.

1406 Cables
All cables are sized in accordance with manufacturers' recommendations and are selected to comply with standard electrical regulations allowing for voltage, maximum current, length and voltage drop. Cables are selected to the highest specification to provide long durability and high safety margins. Light weight cables shall be used where possible.
Electrical designation and marking: All cables are marked at both ends with alphanumeric code to correspond with the ships circuit diagrams. Individual cores are coded similarly.
Cable routes and supports: Wherever possible cables follow a common service route with other services, and are accessible for maintenance purposes. Cables run on cable trays and in ducts secured to the structure, and are placed as high as possible and out of bilge areas. Where cables pass through watertight or fireproof bulkheads appropriate thru-bulkhead glands are used.
Cables will be attached to cable trays and fastened with Tie-wraps.
Separation will be insured between A/V lines and power lines.
Main power distribution lines (EG, Generators, Propulsion motors, thrusters, and large sub panels) will be separated out and run in independent cable trays without wires on top and room all around for cooling.
