The 49-port hubs I received today unfortunately didn't have fuses in them.  Though the fuses are on the way in a separate shipment, I can't wait for a couple of days to be able to used them.  Upon inspection, it looks like they take automotive blade-type fuses.  Is it the Mini Blade fuse?  What's the required fuse amp rating for these hubs?  I wanna head down to the local auto parts store and get them ASAP.

40 amp

Regular in car fuses.  Philipma made an observation that the 40 amp fuse it comes with is way too much for the hub, if each miner uses .5 amp and there's 49 ports, max it should draw is 24.5 amps.  I got a 30 amp in mine and definitely runs cooler than the 40 amp it came with.  The 40 was wicked hot all the time.  Going to try a 25 amp and see if that's the sweet spot.  Don't want an accidental power spike taking out the hub or all them miners.
