SAE J 1908

Electrical Grounding Practice ( Stabilized: Feb 2013 )

SAE International / 21-Feb-2013

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This SAE Standard outlines general procedures for the grounding of electrical components in both 12- and 24-V systems, intended for light and heavy-duty on-highway trucks and their trailers; and off-road machinery applications as described in SAE J 1116.The voltage drops specified throughout this document are for a 12-V system. For 24-V systems, the allowable voltage drops may be doubled. These voltage drops are nominal at room temperature (25 \mDC \mP 5 \mDC), and may not be sufficient to guarantee proper operation of voltage sensitive devices, such as gauges, alternators, and electronic devices. Manufacturer's recommendations for the grounding of components must be followed whenever provided.
