I think we have all been in the position where the van blow as fuse when one of the kids pops a penny in the lighter socket or something happens that blows a fuse, and when you fix the issue you just never have that particular fuse to hand. Putting one in that isn’t the correct rating just to get you by and on your way isn’t ideal, because lets face it.. you are going to forget about that when you get home.
This very handy quality trip switch fuse converts your fuse board so it acts like the RCD trip switch fuse board at home. When the fuse blows and you fix the fault you simply re set the fuse. No rummaging around under the back seat looking for replacement fuses and the correct amp one is always installed.
