This SAE document provides the minimum requirements for a 13-conductor cable plug and receptacle to support the 13-conductor jumper cable between the towing vehicle and trailer. The document also includes the test procedures, design and performance requirements for the plug and receptacle. This document shall be used in conjunction with SAE J3284. The specified 13-conductor plug and receptacle would be totally interchangeable with the current SAE J560 primary plug and receptacle, plus provide an additional 6 conductors for use in trailers incorporating advanced electronics or multivoltage applications. New tractors designed with the 13 conductor receptacle and 13 conductor tractor to trailer cable and plug assembly, would be compatible with old trailers (7 conductor receptacle) and new trailers (13 conductor receptacle).

This SAE standard establishes the minimum construction and performance requirements for a combination cable consisting of 9 conductors and 2 twisted pairs for use on trucks, trailers, and dollies. The cable includes power, ground and 2 jacketed/unshielded twisted paired signal circuits. This standard will be used in conjunction with the SAEJ XXXX “13 Conductor Electrical Connector (Plug and Receptacle) between Towing Vehicle and Trailer”. The standard will also include the test procedures, design and performance requirements for the cable.

This SAE standard establishes the minimum construction and performance requirements for a 15 Pole Connector Between Towing Vehicles and Trailers, for trucks, trailers, and dollies in conjunction with SAE J2742. The connector accommodates both power and ISO 11992-1 signal circuits along with dual ground wires to accommodate grounding requirements within the constraints of the SAE J2691 terminal capacity.

This SAE Recommended Practice covers the design and application of primary on-board wiring distribution system harnessing for surface vehicles. This document is intended for single phase nominal 120 VAC circuits that provide power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off. The power supply comes from alternative sources such as land-based grid power, DC-AC inverters and auxiliary power generators. The circuits may also provide power to improve vehicle performance through charging batteries or operating cold-weather starting aids.

This SAE Recommended Practice defines the test conditions, procedures, and performance requirements for circuit breakers in ratings from 50 to 200 A. The document covers externally mounted automatic reset and manually reset types of circuit breakers for low voltage DC operation (typically 50 V or less).

This SAE Standard establishes the minimum construction and performance requirements for single conductor cable for use on trucks, trailers, and converter dollies.

This SAE standard establishes the minimum construction and performance requirements for single conductor cable for use on trucks, trailers and converter dollies.

This SAE standard establishes the minimum construction and performance requirements for single conductor cable for use on trucks, trailers and converter dollies.

This SAE standard establishes the minimum construction and performance requirements for single conductor cable for use on trucks, trailers and converter dollies.

This SAE Recommended Practice defines the test conditions, procedures, and performance requirements for PTC (positive temperature coefficient of resistance) overcurrent protection devices. PTCs are typically either polymeric (PPTC) or ceramic (CPTC). It is important to note battery voltages versus powernets/system voltage versus max battery voltages: (12 V/14 V/16 V, 24 V/28 V/32 V, and 36 V/42 V/58 V). All voltages are DC. These devices are typically rated with a maximum operating voltage, which for vehicular systems need to be 16 V (for 12 V batteries), 32 V (for 24 V batteries), and 58 V (for 36 V batteries/42 V powernets). PTC devices are considered to be self-resetting after responding to overcurrent conditions and after such condition has been removed from the affected circuit containing the PTC.

This SAE Standard establishes the minimum circuit identification and requirements for Multi-Voltage Power Distribution Systems (MVPDS) for use on trucks and buses. A Multi-Voltage Power Distribution System is one that distributes two or three voltages, up to 60 VDC, to power the controls, instruments, and devices.

This SAE Standard establishes the minimum performance and endurance requirements for coiled electrical cables used for hookup between trucks, trailers and dollies. The component standards SAE J2394 (replaced SAE J1067) for cable and SAE J560 for connectors must be consulted to determine the complete performance and endurance requirements of the system. Related TMC Recommended Practices may be consulted for information associated with selection, installation and inspection of these coiled electrical cables. This document is intended to set out requirements for the majority of conditions rather than for specialized applications or environments.

This SAE Standard provides the minimum requirements for high-power, two-conductor jumper cable plug and receptacle for truck-trailer jumper cable systems. It includes the test procedures, design, and performance requirements. This document covers receptacles rated 12 VDC nominal and at more than 30 A (amperes) up to and including 150 A, and is intended for a single circuit with one power conductor and one common return conductor. Single-conductor high-current connectors are not recommended for future designs because of inadequate ground return through fifth wheel/king pin. Cable size selection is to be made by the vehicle OEM for specific applications and the specific voltage drop requirements of those applications.

This SAE Recommended Practice document covers the general guidelines for conductive power transfer of high voltage Direct Current (DC) power between OEM commercial truck chassis electrical systems and electrically powered body accessory equipment. The OEM chassis can have an EV drive train or be a hybrid chassis with or without a connection for traditional mechanical PTO. The chassis can include use of range extension systems. Voltage levels are defined as greater than 60VDC and include typical EV chassis voltage ranges up to and including 1200VDC . It also covers the functional requirements for the connection systems, body builder communication modes including diagnostics, suggested operational modes, system interlocks and isolation management. The scope of the ePTO physical electrical connection will be limited to a recommendation of the interface concept, space claim and service features and will leave connector features and design open for future definition.

This SAE standard establishes the minimum performance requirements for electrical distribution systems for use in dollies and trailers in single or multiple configurations for 24Vdc and 48Vdc applications.
