This video will help you understand the gantry fuse board - it protects the motor and the claw. Always check this if a motor or claw fails. 10 A is used for main power to the machine in the back plug and the Power Distribution board. It is difficult to read the amperage on the metal ends so keep them separate and labelled in small bags.

Use 3A not 10A fuses!!!!.If you use a 10A in the gantry fuse, motors and claws that get stuck with power on can heat up and become a fire risk. It's very important to use nothing bigger than a 3A fuse in this section.
