Fuses failing from old age is a thing of the past, unless you uses fuses from the past. Modern auto blade fuses will likely outlast your airplane if uses within their specifications. On Jan 26, 2024, ...

I havenâ€™t seen a glass fused used in an auto or aviation application in probably 40 years. I am not aware of any fatigue issues with auto style blade fuses which is what most of use use in cars and ...

Why would a metal fuse have a fatigue life and a wire not?Sent from my iPad

This appears to be a decent source (just placed my first order with them so canâ€™t be sure yet) for genuine Deutsch, Weatherpack and Metripack and they sell single connector kits which are nice to en ...

Yes, Deutsch connectors are good stuff, but pricey. I still use Weatherpack as they are available at reasonable prices for the real stuff. Much of the â€œDeutschâ€ product sold on Amazon are Chines ...

I think we are generally in agreement. I never suggested â€œworryingâ€ about electrical noise, I simply suggested designing it out where it is nearly free to do so. Gently twisting wires has a huge ...

Where does Garmin recommend that? I donâ€™t recall seeing that in the G3X installation manual. Iâ€™ve been an EE for nearly 40 years and donâ€™t recall this being a common practice. Most weather re ...

Well, not exactly. Your point seemed to be that there is never a problem running power and signal lines together so just do it. My point is that this is true most of the time, but not all of the tim ...

The answer is: it depends. For most power (>12 V, low current <10A) and most signal (>1 V, slow transition ms to Î¼s) lines, it wonâ€™t matter much. However, add in higher currents >> ...

In general, I agree with Bob that this issue is overblown by some, but I am not quite as cavalier as is Bob in this regard. I donâ€™t have any experience with aircraft wiring, but I do have 30+ years ...

Yes, one wire in room temp air will carry a fair bit of current. However, bundle a few wires at 12,000 feet and the capacity will be a fair bit less.

It is good the fuse blew at 10 A. I have seen ...

What understanding are you seeking?

From my perspective as an airplane builder, the only understanding I really care about is knowing that the fuses I buy will perform according to the current/time ...

I have also been looking for the same, but have yet to find anything. Bussman makes a 20 slot unit (B&C sell it), but it lacks the indicator LEDs. You can buy fuses with built in LEDs, but they ...

Here is another illustrative test of no-name Chinese fuses. I would think twice before using these in an airplane. I wouldnâ€™t use these in lawn equipment.

I can no longer find the video that actually tested the fuses to failure, but this one shows the problem using fuse resistance as the surrogate.

Be VERY careful using Chinese fuses from Amazon and eBay. I saw a video test of such fuses a year or so back and the results were scary. Basically, all of the fuses were essentially 40 A fuses, even ...
