Heavy-Duty Wiring Systems for On-Highway Trucks
J2202_201912
This SAE Recommended Practice provides general guidelines on the material selection, construction, and qualification of components and wiring systems used to construct nominal 12 VDC and/or 24 VDC electrical wiring systems for heavy-duty vehicles The guidelines are limited to nominal 12 VDC and/or 24 VDC primary wiring systems and includes cable sizes American Wire Gage 20 to AWG 4 on heavy-duty on-highway trucks. The document identifies appropriate operating performances requirements. This document excludes the male-to-female connection of the SAE J560 connectors.
Rationale:
The future of the heavy truck electrical systems will offer a multi-voltage electrical system, which will include voltages above a nominal 14 VDC electrical wiring system, along with new technologies and requirements not included in the current SAE J2202. With the need to include new technologies addressing higher voltage, it was decided to limit the scope of the SAE J2202 to a nominal 12 VDC and/or 24 VDC electrical system.
A revision was also made to this SAE Recommended Practice to reference USCAR-2 Revision 6 and remove reference to SAE J2223/2, which is a cancelled document.
