#11650, "RE: Inline fuse size for a 150watt inverter" In response to In response to 6
thats wierd..i just replied to this but it didnt show up..so possible double post?
anyway, the math goes like this:
it probably draws around 250 watts (considering heat loss), so 250 watts/14 volts= about 18 amps. hook it up w/ 12 to 10guage wire with a 20 amp fuse on the wire and you're set.
