I just hard wired two 12v fans in my V-berth. The fans originally came with cigarette lighter plugs which I cut off. I wired the fans to a new switch rated for 30amps. The fans came with a 800ma slow blow fuse. I cannot find a similar fuse to use in my fuse panel. My fuse panel uses the spade type fuses not the glass stick type. Can I use a 3amp fuse to replace the 800ma slow blow fuses or should I use something rated higher. Thanks!

I would think that a 3a fuse would be plenty for two fans.

I agree.
The formula is 1Amp DC X 1000 = 1000MA's. So a 3A fuse = 3000MA

thanks for the replies. I think I discovered my issue. I think it is the fans themselves. Cheap automotive fans. I tore everything apart checked all the connections and they were fine. Put in another fuse and it blew. I guess you do get what you pay for. Going to but a couple of marine grade fans.

You can get 1amp and 2amp ATC fuses.....But they are not easy to find.... I keep them in stock, but I have to order them online.

My brother and I have used this style over the years and had good service from them.

Look at the questions on that link above.... It gives you the amp draw on that fan in the question at the bottom.

Thanks. It will be new fans for me.
