If you are thinking about adding an LED light bar or making other modifications to your vehicle boat or side-by-side ensure you protect it with an Bussmann Series fuse. This 30-amp inline fuse holder is perfect for many marine and automotive applications. It may be used with ATC / ATO blade-type fuses from 3 to 30 amps with 32-volt direct current power supply. The housing is black with rubber construction while the #12 gauge lead wires are coated yellow and measure 4 inches each. This is a heavy-duty conventional fuse holder without cover. Please be responsible around electricity and consult an expert if you are unsure. Fuse sold separately. Ensure that you always replace an open fuse with one of the same amp and voltage rating and style/dimension.
