These are the fuse holders (on Aliexpress). I went for the holders for the bigger blades (Medium), and you have to select the cable size of that holder: 12, 14 or 16 AWG: The bigger that number, the smaller the x-section. 16 AWD is about 1.3mm diameter, 12 AWG about 2mm and 14 AWG about 1.6mm, and good for about up to 20 or 30A. Maybe go with 14 AWG
