Qman strikes again

Hub motor is here and after some minor issues I'm almost there. The question of the day is:

If I am going to put an inline fuse holder in the power circuit before it gets to the controller. What amp should the fuse be.

I don't want it to blow everytime the motor goes into stress, but I also don't want to smoke the controller.

I shot off an email to the seller but I was curious to see if anyone knew here. He may or may not answer. He has been good so far.

Its a 250 watt hub... I'm thinking 20amp but thats just a guess based on 24 volts at 10amp would be 250 watts, more or less

The 500 watt scooter had 30amp so I took a chance and bought twenty I'll give them a try then move on to thirty if they blow.

Thanks for the input but I just couldn't stand the wait lol.
