Hi Joe:
Will you further explain the statement: "... glow when blown."?
I do recall years ago there were fuse holders for AC that would glow when
the fuse blew. It was a simple circuit of a NE2 bulb and a series
resistor. They were wired in series across the fuse. When the fuse blew
the circuit would become active and the NE2 would glow.
Is this the same idea?
Barry

Barry,
Yes, the principle is the same, except that a LED and series resistor are used
instead of a neon bulb. Of course a load must be connected for the LED to glow.
Vans Aircraft sells them at a very reasonable price.

Same idea, built into the atc fuse.

Right You Are Charlie:
Here is another thought?
In the AC world there is a thing know as a Ground Fault Interrupt (GFI).
It detects a short so fast that YOU can put your hand in a sink of water
and touch an outlet and YOU would not feel a thing.
The GFI would Pop and YOU would be alive. Pretty impressive.
So, why can't they design a circuit like that for DC?
For our EXPENSIVE instruments!
As for the CB protecting the wires and not the device... Well, I have
heard that and read that for years.
It does not protect the device ONLY because it does not function quick
enough to prevent damage.
But, as for protecting the wires... I feel that statement is a BUNK!
If it was only to protect the wires WHY doesn't ALL wires of the same size
have the same size CB?
That statement sure sounds like C.Y.A..
The product manufacture did not want to go the extra distance - spelt -
MONEY. To add protection to the product!
When all else fails - Write a Disclaimer.

Thanks Don,
Ya know guys, the circuit is so simple it can be added to a CB. probably
easier than a fuse.
Good for the CB that is out of the standard field of view.
