Blue Sea USB port install question
Hello All, I installed a Blue Sea USB port in my Bigfoot Truck Camper Saturday. I was wondering what size of fuse would be correct. I have a 10 amp bladed fuse right know. Thanks

Fuses are usually there to protect the WIRE, not the device. Any device that needs a low fuse to protect it - like a stereo - has a separate fuse built in.
As far as the USB gizmo is concerned, you could get by just fine with even a 5 amp fuse. But the REAL question is: Is that the ONLY thing on the circuit, or are there other devices that might be powered on while you are using the Blue Sea? If so, then the fuse needs to be big enough to handle the power ALL the devices are drawing at the same time.
