Electrical System

A.C. Electrical System: Vessel is fitted with two (2) 240 volt AC. House shore power is fed through a 12KVA isolation transformer. Current is distributed through custom PAE electrical panels containing 240 volt AC and 120 volt AC sections, volt and amp meters and individual breakers for functions

Two (2) Outback # VFX3524 3.5 kW 24 volt battery charger/inverters with remote control panels. Inverters are installed in a "series/stack" configuration enabling the vessel to have 120 volt AC and 240 volt AC inverted power. Electrical panel is fitted with an inverter bypass switch in the event of failure

AC Outlets are standard US format in black 120 volt AC. Location shown on drawing

All outlets in head compartment and galley are GFCI type in black

All external outlets have water proof covers

Two (2) Glendinning shore power cord retrieval systems with barrels located in the transom. One (1) each for the 240 volt house shore power and air conditioning shore power. Each system to be provided with 85' (25.9 m) of useable shore power cable from the transom

Standard shore power inlets located on the port side of foredeck


D.C. Electrical System is provided by 24 volt DC and 12 volt DC systems. The primary DC system is 24 volts and the secondary system is 12 volts for any equipment that is only available in 12 volts

Standard batteries are located per PAE machinery drawing and are provided as follows:

24 volt DC house battery bank - consists of twelve (12) 8D, 12 volt "Lifeline" AGM @ 255 Ah each. Two (2) groups of six (6) batteries each are connected in parallel. The two groups are connected in series to provide a total battery bank rating of 1,530 amps at 24 volt. Includes Link 10 battery monitor

12 volt DC power is supplied to the pilot house distribution panel by one (1) Group 31 "Lifeline" AGM @ 105 Ah battery. A Xantrex 12 volt DC 20 amp three bank output battery charger charges the batteries through the inverter

Main engine starting - two (2) 4D "Lifeline" AGM @ 255 Ah each connected in series for 24 volt starting. Switching logic to parallel with 24 volt house bank for emergency starting

Generator starting - two (2) Group 31 “Lifeline” AGM @ 105 Ah each connected in series for 24 volt starting. Switching logic to parallel with 24 volt house bank for emergency starting

Wing engine starting - two (2) Group 31 “Lifeline” AGM @ 105 Ah each connected in series for 24 volt starting. Switching logic to parallel with 24 volt house bank for emergency starting

24 volt battery charging is provided in the following ways:

Outback inverter/chargers provide a total of 170 DC charging amps at 24 volts

One (1) “Skylla” 100 amp charger - TG 24/100 (1+1), part number SDTG2401003. This charger is a back up to the inverter/charger and serves as a battery charger when the vessel is in a 50 Hz environment

Main engine starting battery bank is charged from the house bank thru a diode isolator

Onan 27.5 kW generator has its own 20 amp 24 volt alternator which charges its starting battery

Wing engine has its own 100 amp 24 volt alternator which charges its starting battery


Battery cable: to be sized per electrical drawing and color-coded per PAE drawing


When possible wiring to be color coded per ABYC standards


All wiring to be "tinned" copper


All wiring connections except behind electrical panels to be sealed with "shrink wrap". Connectors to be ring type with closed end seamless construction


Lightning ground system per PAE drawing


Preparation for SSB radio ground: ground ribbon only, ran from pilot house to lower machinery space (external ground plate optional)


Electrolysis control per PAE drawing

All thru hulls to be bonded together with a # 6 green wire and tied into the DC ground system

All hardware mounted below water line - i.e. stuffing box, rudder shoe, rudder frame, all thru hulls, engines, and strainers to be grounded into bonding system

Three (3) zinc plates to be tied into the bonding system

"Perry nut" zinc on end of propeller shaft


AC Genset - Onan # MDKBT 27.5 KW 24 volt DC with sound shield providing 120/240 volt AC current at 60 Hz

Generator fuel filter- Racor 900MA

Gen-sep exhaust system


Electrical Panels

Main AC distribution and control panel located per PAE drawing

Main DC distribution and control panel located per PAE drawing

Sub distribution panel in wheel house and Lazarette

House battery control panel located in lazarette

Engine/gen start battery and emergency parallel control panel at entrance to engine room

Generator start/stop panel located at main electrical panel
