Features
Issuing Committee
Scope
Content
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
Content
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.
