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 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 establishes the minimum performance and endurance requirements for coiled electrical cables used for hookup between trucks, trailers, and dollies for 12 VDC nominal applications.

This SAE Standard defines the test conditions, procedures, and performance requirements for circuit breakers in ratings up to and including 200 A. The document includes automatic reset, modified reset, and manually reset types of circuit breakers for 12 VDC, 24 VDC, and 48 VDC electrical systems. Some circuit breakers may have dual voltage ratings (AC and DC); however, this document evaluates DC performance only.
