Tech Talk: American Tug 395 Electrical System

Learn why the American Tug 395 electrical system is so well done.

New American Tug AC & DC electrical panels by Blue Seas.  The Best!

The American Tugs have always  been known for their beautifully engineered electrical systems.  Kurt Dilworth, VP of Engineering at Tomco Marine takes great pride in the quality of their gear and clean installations.  With the AT-395 and the 435 Kurt is able to introduce the new Blue Seas "360" custom distribution panels.  Blue Seas is a local company, located in Bellingham just 25 miles north of Tomco's shop in La Conner, WA.  Blue Seas has become the industry leader by introducing innovative electrical products of the highest quality.  It is wonderful to have them as a neighbor.

The new DC panel has illuminated battery switch controls.

The DC panels allow Kurt to integrate illuminated battery switch controls right into the panel, allowing our owners to turn on or isolate the batteries from the helm station.  This provides instant acknowledgment of switching without having to go into the mechanical spaces, and provides the safety advantage of being able to disconnect the batteries very close to the electrical source.  The remote switches control the house, engine start and automatic battery combiner circuits. 

Batteries and remote battery switches located in the mechanical space under the salon.  Lid is open.

The Absorbed Glass Mat (AGM) batteries are located in secure battery boxes in the mechanical space under the salon.  Blue Seas remote controlled battery switches are close by, allowing control and emergency shut off if needed.   The  battery switches feed the DC distribution center located nearby in the same space.

Electrical DC distribution center.

In the same mechanical space as the batteries is the DC electrical distribution center.  This houses the primary DC fuses that feed the DC panel in the pilothouse, the power inverter, dinghy crane and 24-hour circuits (bilge pumps, etc).  The distribution center is a wonderful design as it allow a high quality integration of systems, while keeping it simple and easy for owners to operate.  All elements are clearly labeled and easily identified.  The layout is clean and logical.  All parts are of the highest quality.  Blue Seas electrical components are made in North America and are now the benchmark of quality. 

The AC & DC panels are hinged allowing easy access to the systems behind. 

Two stainless machine screws, unscrewed from their stainless nutserts for a lifetime of dependability, allows access to the wiring and distribution behind the panels.  All wire is pre-tinned stranded yacht cable per ABYC recommendations, for maximum flexibility and corrosion resistance.  Kurt designed these systems for extreme durability.

Lighting circuits are controlled by replaceable automotive style relays for convenient field servicing.  The switches located around the boat for convenience only carry low amperage so as to not burn out or fail prematurely, the actual lighting loads are switched by relays for dependability.  Wires are all labeled and run in organized bundles.  This is the quality of wiring that a boat builder can pride themselves on.
