What Fuse to Use

[Dingo Dog]

Hello Gents

I have installed a BlackVue car cam into the dragons car, that was the easy part. To install the PowerMagic hard wired controller I will be using the "add a fuse" device. As i am not eletronic smart when trying to work out what fuse amperage i need, theses are the ratings on the device.

Rated current 1A, Max 2A/Below 200mA

My qusetion is, what amp fuse do I need..

General rule of thumb is 25% on top of max expected current flow so 2.5A should be fine. However, sometimes they are hard to get so 5A would be O/K

The fuse is there to protect the wire...so base the fuse size on the gauge of the wire used.

Thanks Blokes for the info, will go and buy a couple of 5amp fuses.

And wire size is chosen for current flow and length.
