A 100 watt landing light in a 13.5 volt system pulls a current of 7.4 amps and could use a 7.5 amp fuse or CB if you don't consider wire length.
Yes Rich you are right I should have ended that example by saying "if you don't consider any other factors". There are other factors besides the size of the wire. I wanted the Net to know that there is a way of conputing some of the information, other then to guess. Orma L. Robbins o...@aviation-mechanics.com
