In an intense present overload situation, the conductor inside the link is melted whilst the ensuing flame and spark is contained inside the link’s insulation. What are the ratings for fusible links?Fusible links are not rated in amps like fuses because every installation is unique and designed to meet particular circuit protection requirements. What size replacement fusible link ought to be used ?The automotive service industry recommends utilizing the exact same gauge and length as the blown fusible link following the trigger of failure is corrected. How do you use a parallel connector?Insert the stripped finish of a fusible link and the stripped finish of the cable being protected into a parallel connector as shown, and crimp. A parallel connector ought to always be protected with electrical tape or heat-shrink tubing.What size fusible link should be used in a new installation?The suitability of a fusible link in a new application can be determined only by a qualified harness engineer with complete understanding of the circuit protection requirements, the installation and operating conditions, and the safety and liability elements.
