Regular style fuse holder for cars. Get a 20-amp or 15-amp fuse from your local auto store. FUSES – You can easily use a regular 20-amp fuse from AutoZone or any other auto store, or you can use a thermal resettable fuse. The video instructions show a thermal fuse being used in Video #3. You can use either option. If you purchase the wiring kit you will receive the resettable fuse for your generator. | ![]() |

A thermal fuse gets hot when too much current flows through it and then opens up until you stop pedaling. This is called an overcurrent protection device. After 20 to 200 seconds, depending on how hot the ambient conditions are, the thermal fuse will cool down and the pedal power system will be ready to use again. This fuse should never trip, but if it does, it means there is something wrong with your wiring. | ![]() |
