Clipsandfasteners (5) 10 Gauge Fusible Link Wires, 9" Length, Compatible With GM 12077140

The lower the gauge number, the thicker the wire (i.e. 10 ga. is thicker than 16 ga.)A fusible link is a special section of low tension cable installed by an OEM and designed to open a circuit when subjected to extreme current overload. Its purpose is to minimize wiring system damage when such an overload accidentally occurs in those circuits protected by the fusible link. A short circuit causes the fusible link to act as an element in a ?slow-blow? fuse. A fusible link is not intended to be used in place of a fuse but only where a fuse cannot be economically employed. Our fusible line wire meets the requirements of SEJ-156 and the insulation has the characteristics as listed for EAE, SE J-1128Type SXL. The vehicle manufacturer should be consulted about questions on fusible link length and size. General practice has been for a fusible link to be 4 gauges smaller than the circuit wire. Example: if the circuit wire is 12 gauge, use a 16 gauge fusible link. Final determination should be based on O.E.M.application.Note: Extreme care should be taken to always replace a fusible link with the same gauge and length as installed by the manufacturer.Universal Fusible LinksGauge: 10Length: 9 InchesCompatible With GM: 12077140(5) 9" Lengths Per Package
