ABYC Ampacity Rating Table at
30°C
- For bundles of 4 to 6 conductors multiply by 0.857
- For bundles of 7 to 24 conductors multiply by 0.714
- For bundles of 25 or more, conductors multiply by 0.571
SAE conductors are smaller than equivalent AWG by 5%–12% with current
capacity typically less by 7%.
ISO Ratings for metric wire are slightly less than these values derived from
ABYC VI-A ratings.
Wires counted in bundles need not include:
- Wires carrying intermittent currents no more than rating per VI-A and for
less than one minute per mm of diameter‚ and not repeating more often than a
delay of 5 times active duration.
- Wires carrying load currents at less than 50% of the wire rating per table
VI-B.
Battery Management Wiring Schematics for Typical
Applications
Batteries are at the heart of the electrical systems found on any boat or
vehicle. Proper battery management, including switching and charging, is
essential for safe and reliable operation. The following basic wiring diagrams
show how batteries, battery switches, and Automatic Charging Relays are wired
together from a simple single battery / single engine configuration to a two
engine, one generator, and four battery bank system. For more detailed wiring
guidelines please consult a qualified marine electrician or one of the many
books available on the subject.
The diagrams below are intended for reference only. Consult an ABYC
certified marine electrical professional for system design and circuit
protection.
Switches isolated battery banks to all loads or combines battery banks to
all loads
1 Selector Battery Switch
1 Automatic Charging Relay
Simultaneously switches two isolated battery banks or combines battery banks
to all loads.
1 Dual Circuit Plus™ Battery Switch

Can isolate a failed battery
Conformité Européenne (CE)
The CE mark is the official marking required by the European Community for
products that will be sold, or put into service for the first time, anywhere in
the European community. It proves to the buyer or user that a product fulfills
all essential safety and environmental requirements for the product's intended
use, as they are defined in the European Directives, primarily ISO Standards,
but in the case of marine products, the Recreational Craft Directive as well.
In return for fulfilling the CE marking requirements, the manufacturer or its
agent may cover the entire European market using only one approval procedure for
the topics covered in the directives.
The member states of the EC cannot refuse any product that has been CE
marked, unless fraud is suspected. For some products, however, national
regulations may exist, as long as the topics covered in these national
regulations are not covered by a pan-European Directive. An example is
Ergonomics in Germany for PC-related equipment.
A manufacturer that is using the CE mark must:1. Be European,2. Or have an
official department in the European Community,3. or have an official agent or
representative that is willing to take the liability for the CE-marking.
The attachment of the CE mark to a product must be based on a formal
compliance statement which usually takes the form of a Declaration of
Conformity. The Declaration of Conformity is a "self-declaration" statement that
must contain: 1. Who the manufacturer is2. What product the Declaration refers
to3. What directives are involved4. What standards are applicable5. Where test
results can be found6. Who the responsible individual is in the declaring
company
The Declaration of Conformity should be available to the authorities at the
point of entry on the European Market. This means that it should be signed by
the manufacturer's European representative for companies outside the EC. Its
main purpose is to show proof of liability for compliance with EC regulations
involved to the authorities and customs.

The 360 Panel System
The 360 Panel System uses an open frame to mount a broad
selection of modules, allowing multiple functions to be combined in a single
panel.
This innovative design offers a wide choice of panel features,
can accommodate future changes and permits rapid assembly. With options ranging
from battery management to source selection, the 360 Panel System provides
unmatched design flexibility.
