DC Motor - Fuse or Breaker, Size, and placement?

[[email protected]]

I am building an electric Go Cart.

The motor is a 36 Volt 80 Amp motor.

The 36-48 Curtis 225 Amp controller is from a Golf Cart.

I understand that I should place a fuse/breaker at the battery before
th controller, and another from the controller to the motor. An on/off
switch to the pot. throttle.

1> Fuse or DC breaker?

2> What size?


Thanks

Something around 80A should do the trick, if that blows go up a bit higher
but don't exceed what the controller or wiring can handle. Car stereo shops
should have something suitable.
