Wire
Gauge   
00 awg  400 amps
0 awg   325 amps
1 awg   250 amps
2 awg   200 amps
4 awg   125 amps
6 awg   80 amps
8 awg   50 amps
10 awg  30 amps
12 awg  20 amps
14 awg  15 amps
16 awg  7.5 amps

These are the recommended maximum fuse ratings for the corresponding
wire size. Using a smaller fuse than what's recommended here will be
perfectly safe.


I got this chart off of an electronics website.  These maximums are
designed to keep the wire from burning up (ie: starting on fire).
According to this chart, my fuses are too big for my wire size.  The
M-01 motors Joe sells have blown 30 amp fuses in a stall.  I'm
thinking I need to put some smaller fuses in my tank.  Yes you EV's
will have a higher stall current at 24V, but they should also draw
less amps at 24V under the same load at 12V.
