There's also a separate 6A fuse protecting the rest of the K3. Anything in the power cable is strictly redundant. I don't use one.

I believe that the circuit breaker only protects the KPA3. If you're running off battery, or other unprotected power-source, I think you would really want an external fuse (as close to the power source as possible, in case you get a short in the supply cable somehow). 73, ~iain / N6ML On Thu, Jun 13, 2013 at 6:06 PM, Michael Eberle <[email protected]> wrote: > Yes, that is a circuit breaker on the K3 so a fuse probably is not > necessary.
