Dear samiam:

I am trying to get the parts for samiam's automatic HVAC fix togeher. I have a question on the fuse rating. How do you determine the correct fuse rating? For example, I found a 12vdc, 0.7W fan at All Electronics. If you do the math: W=VI. I=W/V So 0.7W/12VDC=0.058I (Amps) In your parts list you spec a 6amp fuse. But I have no idea the ratings of the fan samiam has choosen, so I cannot copy his method of choosing a fuse. If anyone can offer advice, I'd be grateful. Thank you.

I imagine a 1 amp fuse will work if your load is 0.05 amps. Perhaps he chose a 6 amp fuse to protect the wire. I think a 18awg wire can handle around 7 amps.
