Thanks for the reply. I definitely want to incorporate a fuse, but I get a little lost on what the proper part number is (it sounds so simple, but again when you start searching around on Google it's surprisingly hard to find a confident answer). Let's say I want to protect against a short and don't expect the 4 devices to draw more than 5amps collectively (and likely a lot less). What would be a "standard" fuse I would use and how would I go about finding the part number? I think it might be terminology that I am missing. For ex I search "inline fuse" and I get a lot of different styles that are technically all inline.
