Using our new crimper, James takes you through the process of crimping MC4’s.
Step 1: Make sure you have a clean square cut on the end of the cable. Then we get our crimper and line the correct size into the correct slow (4mm cable into the 4mm slot), approximately 5-6mm and we strip the double insulator off.
Step 2: Get our MC4 pin and insert it into the crimper. Then insert the cable into the pin and squeeze the crimper.
Step 3: Then put on the MC4 and make sure you hear the click. Then take a spanner and tighten the lock nut.
