3. Definitions
3.1 Coated Wire—Wire comprised of a given metal covered with a relatively thin application of a different metal.
(See ASTM B 354.)
3.2 Fusible Link (Fuse Link)—A section of low tension cable designed to open the circuit when subjected to an extreme current overload. Its purpose is to minimize wiring system damage when such an overload occurs.
3.3 Low Voltage—Usually considered to be ≤60 V DC (25 V AC).
3.4 Short Circuit—An accidental electrical connection between a feed circuit and a return circuit resulting in an extreme current overload.
4. General Requirements—The cable should meet the applicable requirements of SAE J1 1 28, J1 654, or J1 678. Cables other than those defined in SAE J1 1 28 or J1 678 may be used if they meet the functional requirements described in 5.1 and 5.2.
4.1 Conductor—When bare or coated copper conductor is used, the conductor shall meet the requirements of SAE J1 1 28 or J1 678. When conductors other than copper or coated copper are used, the conductors must meet the functional requirements described in Section 5.
4.2 Insulation—Regardless of the type of insulating material used, the fusible link shall meet the performance requirements of SAE J1 1 28, Type TWP for dielectric (withstand voltage), cold bend, flame, fluid compatibility, pinch, and abrasion. When the wire size of the fusible link does not match one found in SAE J1 1 28 or J1 678, the next larger size shall be used.
