What are the ratings for fusible links?Fusible links are not rated in amps like fuses because each installation is distinctive and developed to meet specific circuit protection requirements.
What size replacement fusible link should be utilized ?The automotive service business recommends using the exact same gauge and length as the blown fusible link following the cause of failure is corrected.
How do you use a parallel connector?Insert the stripped end of a fusible link and the stripped end of the cable being protected into a parallel connector as shown, and crimp. A parallel connector should usually be protected with electrical tape or heat-shrink tubing.
What size fusible link should be utilized in a new installation?The suitability of a fusible link in a new application can be determined only by a certified harness engineer with full understanding of the circuit protection requirements, the installation and operating circumstances, and the safety and liability elements.
