43-13B is acceptable methods not absolute requirement. The mfr'r (Cessna) had their reasons and their design is approved.Lee wrote:Thanks for the diagram ... interesting ... useful info ... much appreciated. I will pass the word once I figure out how I am going to do the LED interior lights. By the way, this morning I was reading AC 43-13B this morning and found an interesting comment on page 11-15, para 11-50 (b) ... “Automatic reset circuit breakers, that automatically reset themselves periodically, are not recommended as circuit protection devices for aircraft.” I may be missing something but, this sounds like the 2 amp thermostat/current limiter (Klixon) I found behind my instrument panel ... thoughts?

Well, I am surprised at the recommendations made to you by Whelen. The 18 or 16 ga. wire is protected by Cessna with a 10A fuse. ...and as we've already noted... the circuit limiter used protects the WIRE....not the appliance.Lee wrote:I agree George ... “wires and fires” are to be taken seriously. In my previous life, we could reset a breaker (other than fuel boost pump) if in flight and the item was needed. If in deck, we had to contact maintenance and let them deal with it. Interesting that Cessna had the auto reset current limiter/breaker ... I may be missing something but it sounds to me like the current limiter/breaker/thermostat could trip if too hot, cool down and then re-set automatically ... and we have no control over its functions? This is another reason I wanted push-pull breakers instead of pop-out breaker and/or fuses as was the case with my airplane. If things are going awry electrically, I want to be able to positively remove power.
Here is something that struck me as well: I talked to Whelen yesterday regarding the size of breakers to use for their Orion LED Nav/Strobe lights. They recommended 16 or 18 ga wire and a 15 amp breaker for three Nav lights and a 15 amp breaker for three strobe lights. Oddly, the lNding and taxi lights, also Whelen LEDs, combined, are 5 amps ... recommended. Given how little the LEDs draw, the impression I have is that the higher ratings for the Nav and strobes are due to the length of the wires. Any thoughts?
Also ... what does a heated pitot draw? I can’t find a reference ... also appears the stall warning actuator is heated? Thoughts, comments appreciated! Regards, Lee
