----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- According to AC 43.13-1A (the new edition is at the hangar, but I don't think this section has changed):
Nav lights (less than 1AMP - approximately 15 ft run) #20. Strobe power supply primary wiring (3AMP - approx. 10 ft run) #20 Strobe secondary wiring (high voltage insulation needed - current drain is small) - follow manufacturer's recommendation. Landing light (100watt = 8AMP - approx. 12 ft run) #16 Practically speaking, we don't use anything under #18 for power wiring because it is hard to handle and prone to break strands when an item like the tailcone is repeatedly removed for inspection or service. We reserve smaller sizes for behind the panel avionics and sensors that don't move and are rarely serviced. The sizes shown above are the minimum for inclusion in wire bundles. They should be "real aircraft wire," sold by most avionics distributors. The type is not very important for this use, as long as it is one of the ones spec'd in AC 43.13. Screw lug connections should have the proper kind of washers in the right order. Crimp connections should be tight and tested, with no broken strands. Now, how come you don't have a copy of AC43.13 of your own, if you are working on an aircraft?

What gauge wire should I use? __________________________________________________ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] ___________________________________________________________ T O P I C A The Email You Want. http://www.topica.com/t/16 Newsletters, Tips and Discussions on Your Favorite Topics
