This SAE Recommended Practice covers the requirements for all marine inboard engine wiring, wiring assemblies, wiring components, and wiring connectors connected to microprocessors associated with the operation of the propulsion system, operating at 50 V or less.
EXCEPTION—Outboard engines and engines in Personal Water Craft (PWC).
NOTE: See ABYC E11 for additional requirements related to electrical installations on small craft.
Rationale
Remove the schematic diagram examples shown in Figure 5, and the reference to J 2202 in the reference section. Also removed SAE J1128 as an alternate reference in section 11. They represent older practices, and are only shown as examples for the purpose of clarifying color coding and were not meant to be recommendations of circuiting or component use. The industry has a well established practice of providing good wiring diagrams so the figure is unnecessary. Review and revise the color code chart to be consistent with current practice. Clarify scope to exclude high voltage DC Hybrid systems which are covered by specific standards.
The Marine Technical Committee develops and maintains SAE Standards, Recommended Practices and Information Reports for the development, production, application and testing of marine vehicles and equipment. The committee also maintains liaison with the American Boat & Yacht Council (ABYC), Canadian Coast Guard (CCG), International Council of Marine Industry Association (ICOMIA), International Organization for Standardization (ISO), National Fire Protection Association (NFPA), National Marine Manufacturers Association (NMMA), United States Coast Guard (USCG), and other organizations as necessary. The subcommittees formed under the committee's direction include: Marine Engine Fuel Systems Marine Electrical Systems Participants in the SAE Marine Technical Committee include OEMs, suppliers, consulting firms, government and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
